Renishaw’s optical encoders selected for 'unique' linear motor

Constant velocity control is essential for many advanced industrial processes, but traditional motor designs give rise to cogging forces which generate ripples in the motor velocity. KOVERY has designed a series of advanced linear motors, with integrated Renishaw encoders, that solve this problem.

Background
Linear motors are widely used in major industrial fields, including flat panel display (FPD), semiconductors, automation, medical diagnostics, 3D printing, and machine tools. A linear motor is equivalent to a rotary synchronous motor with a ‘rolled-out' stator and rotor. Instead of producing a torque for rotation, it produces a thrust force along its length.

KOVERY is an ultra-precision motor manufacturer based South Korea. Renishaw's QUANTiC series of incremental encoders are employed in KOVERY linear motors for the commutation and position control. The encoders are critical components that give reliable position feedback in challenging environments.
