Linear motors are linear 3-phase servo motors in various sizes and any length. They consist of a primary (coil pack) and a secondary part (magnetic rail).
The primary part is conducted by a linear slide, and the secondary part securely mounted in the field of the guide.

For short travel distances, it is useful to mount the primary part securely and to run the magnetic guide as the moving part.
The measuring tape is attached parallel to the guide, at wich the sensing head is securely attached to the primary part. Depending on the dynamics and accuracy, optical or magnetic measurement systems are used.
The integrated Hall sensors provide the position information for the commutation of the motor.

The primary part features a temperature sensor to protect the motor. Permanently electrical connection (Hall, spools and temperature sensor) is made via permanently attached cables.

Vantages

The direct power transmission eliminates all mechanical transmission elements such as spindles and tooth belts, completely eliminating any friction and backlash.

This allows higher speeds and dynamics to be realised. The therefore reduced cycle times lower production costs and increase productivity.

Since the drive itself does not contain any mechanical elements, noise, wear and maintenance costs incurred are minimised.

Drive mechanisms with linear motors compared to other linear drives are more accurate, quicker, free of backlash (no dead signal range) and more robust.
