These linear motors are supplied with an internal shaft supported by two linear bearings.
Applying a voltage across the terminals of the motor causes the motor to move to one direction. Reversing the polarity of the applied voltage will move the motor to the opposite direction. The generated force is proportional to the current that flows through the motor coil. This force is almost constant in the specified stroke range of the motor.

These types of motors do not need commutation and using a position sensor, positioning accuracies as small as one micron or 0.00004 inches may be achievable.

The non-commuted motor construction increases reliability. The direct coupling of the motor to the load allows for fast acceleration / deceleration and high speed operation.

This motor may be used in conjunction with a position sensor and a motion controller for accurate positioning.

For proper heat dissipation the motor should be mounted on a metallic body with adequate surface area in an unrestricted flow of air.
