     ServoRing Rotary Tables

ServoRing™ direct drive rotary brushless motors are used in applications where superior angular positioning and velocity control are important. Applications range from tool indexing to high speed laser machining to precision semiconductor manufacturing. ServoRing™ motors can be supplied as a stator/rotor assembly for integration into customer machine. The rotor consists of steel ring with bonded high strength magnets.  The stator ring frame includes laminations and coil windings. The motor is extremely compact. Water cooling jacket is also available. ServoRings™  are compatible with a wide range of servo amplifiers.

 

ServoRing rotary tables can be supplied as an integrated turn-key assembly.
