The CLD Linear Motor is essentially a conventional brushless motor with an unconventional twist.

The design of CLD’s core patent began with the magnetic design of a rotary brushless motor. Engineers cut the rotor lengthwise, laid it out flat, and then curled the assembly into a tube from the other direction. The permanent magnets now formed a stack of rings in alternating magnetic polarity. Engineers suspended the magnetic shaft in a column of current-carrying coils held in slots along a metallic core – the stator.

The company’s engineers then rebuilt the shaft using more powerful magnets to increase the force produced, and lengthened the motor to create a longer stroke.
The result of these design improvements is the CLD linear motor : a motor about the size of a blender with all the advantages of existing technology and none of the disadvantages.

In short: a motor poised to replace a portion of today’s pneumatic and ball screw, as well as some hydraulic motion control technology.
