 | HyCore™
Baldor has redefined linear motors with a technological breakthrough. Baldor’s new HyCore™ motor combines the best features and performance of traditional high speed, high force, closed loop brushless linear servo motors, with the cost advantages of open loop linear stepper motor technology. HyCore™ includes benefits, which linear motors bring to an application: zero backlash; high efficiency; unlimited travel; fast velocities and high accelerations.
Linear motors consist of two parts - a stationary ′′platen′′ and a moving ′′forcer′′. Baldor’s unique HyCore™ contains no magnets on the stationary platen, thus it can easily be cut to length to suit the application. This also includes the benefit of not attracting metal particles.
The HyCore™ ′′forcer′′ consists of a three phase servo motor winding. It is controlled via closed loop using feedback from an external encoder. This provides benefits of higher performance, higher forces, and improved accuracy.
Baldor’s new HyCore™ provides the highest forces per cost of any linear design available in the marketplace. Additionally, the continuous force capability can be extended by 20% with air cooling, increasing value further.
HyCore™ is extremely cost effective in applications requiring long stroke or high continuous duty. It has been designed to replace ball screw and belt/pulley actuators in many applications.

 | Brushless Cog-FreeLMCF series
The Cog-free brushless linear motor is designed for unlimited stroke (travel) servo applications that require smooth operation without cogging. These motors are supplied in kit form to be integrated into a customer’s machine. They are used in closed-loop servo systems and provide optimum performance.
The linear brushless AC Cog-free servo motor consists of a stationary magnet track and a moving coil assembly. The U-shaped, multi-pole magnet track is comprised of alternating polarity rare-earth magnets bonded to a hardchrome plated, cold-rolled steel plate. Modular track assemblies stack end to end to provide the length of stroke required. The coil assembly must be centered within the U-shaped magnet track and guided by customer supplied bearings. Individual coil assemblies can be mounted in series (as a single unit) to increase force. Multiple coil assemblies having independent operation and overlapping trajectories can also be mounted on a single
magnet track.
The moving primary is a three-phase ironless core coil. The winding is encapsulated in thermally conductive epoxy. The ironless core eliminates the magnetic-attractive force between the coil assembly and the magnet track. A twisted shielded four conductor high flex cable supplies power to the coil assembly. The standard coil assembly is provided with Hall sensors for sinewave commutation alignment, trapezoidal commutation, and crash recovery. Custom designs without Hall sensors are available. An aluminum mounting bracket is integrated with the coil assembly. For improved heat dissipation and increased force, a water cooling option is available on some models.
All specifications are for reference only.

 | DC Brushed Linear Servo MotorLMBR series
The brushed linear servo motor is designed for long stroke servo applications. It is ideal for direct linear motion without mechanical linkages in closed-loop position packages.
The moving permanent magnet brush commutated DC linear motor consists of a stationary primary and a moving secondary. The stationary primary is a steel laminated core, with multiple coils inserted into insulated slots. The ends of each coil are connected to a commutator bar that is mounted on an aluminum angle.
The moving secondary features multiple permanent magnets and brushes for commutation. A cable supplies power to the moving secondary. Mounting holes are located on both the primary and secondary.
The magnetic-attractive force between the primary and secondary can be used as a magnetic preload for the bearing system. The customer-supplied bearing system must maintain an air gap of 0.064 cm [0.025 inch] between the primary and secondary. The brush linear motor is available in different cross sections to meet different force requirements. |
 | AC Linear Induction MotorsLMAC series
The Linear Induction Motor (LIM) is designed for highforce, long-stroke applications, such as material handling and people movers.
The single sided Linear Induction Motor consists of a primary coil assembly and a secondary called a reaction plate. The coil assembly is comprised of steel laminations and phase windings with a thermal sensor encapsulated in thermal epoxy. The customer supplied reaction plate is made of 3.2 mm (1/8 inch) thick aluminum or copper plate bonded to a 6.4 mm (1/4 inch) thick cold rolled steel. The aluminum faces the coil assembly. The width of a reaction plate must be equal to the width of the coil assembly. A customer supplied bearing system is used to maintain the 3.2 mm (1/8 inch) airgap between the coil and reaction plate over the length of the stroke.
When AC voltage is applied to the coil windings, a traveling magnetic field is created. This induces current in the reaction plate which in turn creates its own magnetic field. The interaction of the two magnetic fields generates the force and direct linear motion.
Either assembly or the reaction plate can be the moving member of the motor. Typically the reaction plate becomes part of the customer load moving over stationary coil assemblies placed end-to-end for the travel distance. In this configuration the length of the reaction plate must be equal to the center to center distance of two adjacent coil assemblies plus the length of one coil assembly. This will ensure the reaction plate covers adjacent coil assemblies at the point of transition from one coil to the next. Should the coil assembly be the moving element of the motor then the reaction plate length must be equal to the length of stroke plus the length of one coil assembly.
Using two LIMs facing each other can provide increased force. This is known as a double sided linear induction motor. Here the reaction plate will consist only of a 6.4mm (1/4 inch) thick aluminum plate without steel backing. The aluminum will require additional support over the length of the stroke.
A variable frequency inverter will provide velocity control of a linear induction motor. A Linear Induction Motor (LIM) equipped with a linear encoder can do point to point programmable positioning when driven with a vector control and motion controller. These motors are supplied in kit form with customer providing reaction plate (secondary) and bearing system to be integrated into the application. |

The forcer is made of two laminated steel cores precisely slotted with teeth and a single permanent magnet. The coil is inserted into the laminated assembly. Leads are provided at the beginnings and ends of the coils. Two interconnected assemblies result in a 2-phase motor. Four interconnected assemblies result in a 4-phase motor. The laminated assembly is encapsulated in an aluminum housing. The forcer is available in different sizes, depending on the application’s force requirements.
The platen is a photo-chemically etched teeth on a steel bar filled with epoxy, ground and hard-chrome plated. Standard mounting holes are provided on forcer and platen. The platen is available in lengths over 2.54 m [100 in]. The magnetic-attractive force between the forcer and platen is used as a preload for the bearing system. The platen to forcer air gap is maintained by the integral bearing system. The customer must bring power to the forcer with an umbilical cable. |

The compact dual-axis stepper motor provides travel along two axes in a single plane.The dual axis package is comprised of two components: a moving forcer (with bearings) and a stationary platen. A position verification system is available to close the loop.
The dual-axis linear stepper motor is designed for two-axis open loop positioning. It is a two axis stage with integrated air bearings and positioning system.
The moving primary 2 or 4-phase dual-axis linear stepper motor consists of a moving forcer and a stationary platen. The forcer is made of four single-axis coil assemblies. Two of the forcer assemblies are mounted in series to provide a thrust in the X direction and the other two are mounted orthogonal (at 90 deg.) to the first two assemblies to provide thrust in the Y direction. The forcer assemblies are encapsulated in a hard anodized aluminum housing. The motor’s surface is lapped to provide a flat surface for the air bearing. The floating height of the air bearing is less than 25 μm [0.001 in]. The forcer is available in eight sizes, depending on the application’s
force requirements.
The platen is a photo-chemically etched steel plate that is filled with epoxy and ground. Standard mounting holes are provided on forcer and platen. The platen is available in sizes up to 0.24 m x 0.34 m [36 in x 59 in]. Preload for the bearing system is provided by the magnetic-attractive force between the forcer and the platen. The customer must bring power to the forcer with a cable, and provide the bearing air supply. |
 | Polynoid Linear Motor
The AC polynoid derives its name from the solenoid but the similarity stops there. Unlike a solenoid, the polynoid is a linear electric motor.
The AC Polynoid provides a constant force for the entire length of its stroke. Its direction of travel is reversible by switching with equal force in both directions. Switching requires the swapping of any two of three motor leads in three-phase units while single-phase reversing is done by the swapping of one line lead to the opposite side of the capacitor lead. Electrical force reversal can be used for dynamic braking.
A polynoid is comprised of two basic parts, a rod and a stator. The rod is copper clad steel, the end of which can feature a tapped mounting hole. An optional holding coil is available for end holding at one or both ends. The stator is a series of coils wound on bobbins. Coils are interconnected. The stator is housed in a smooth cold rolled steel assembly. It is also available finned for greater heat dissipation.
The polynoid is an electrical induction motor. A sweeping magnetic field along the length of the stator coils induces linear motion of the rod through the stator or stator along the rod. The rod reacts to energization in less than 10 msecs accelerating to a limited speed. The time to reach this speed depends upon the net force available and the mass being moved. Normal operating speeds to 1.3 m/s (50 in/sec) for single phase units with three-phase units going to 2.3 m/s (90 in/sec).
The rod can be of infinite length when provided with proper support. Output force can be as high as 445 N (100 pounds) per stator with design capability for greater. The force can be controlled by varying the applied voltage (force varies by the square of the voltage) resulting in a degree of speed control.
FINNED SERIES provides maximum heat dissipation and higher duty cycle. SMOOTH SERIES is designed for applications where space is restricted. The smooth finned series provides force equal to the finned series, but at a lower duty cycle. |
 | Non-Commutated DC Linear Motor
Moving Coil and Moving Magnet non-commutated linear motors provide short strokes with constant force over the full stroke in both directions. The motors provide a very fast response because of a low (<1msec) electric time constant.
Non-commutated DC linear motors operate at very high speeds without cogging or force ripple and with infinite resolution. For closed loop operation, the motor is coupled with an appropriate feedback device, motor control and motion controller.
The Moving Coil model consists of a cylindrical coil that moves within an annular air gap of the magnet assembly. The poles are magnetized by rare earth magnets. When DC voltage is applied, the coil is caused to move with constant force. When polarity is reversed, the direction of travel is reversed. Magnetic-attractive forces and hysteresis loss are eliminated. Also, eddy currents can be eliminated by utilizing a plastic bobbin.
The Moving Magnet model is like a piston moving within a cylinder. The piston consists of permanent magnets with steel pole pieces and a shaft that passes axially through its center. Endcaps with bearings on both ends of the cylinder support the shaft. The cylinder contains a bobbin to support the coil and an outside steel tube for containing the magnetic flux. DC voltage applied to the coil causes the assembly to move and when the polarity is reversed the direction of travel is reversed.
