LMCF 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.

LMBR 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.

LMDS Series


The open-loop linear stepper motor provides the most economical linear motor positioning package. 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 m [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 0.24m x 0.34m [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.
