Hollow shaft 'pancake' servo motors
Hauppauge, N.Y. - Hollow shaft servo motors using PMI's 'ServoDisc' technology have been added to the company's Platinum Series (brush dc) and PlatinumXT Series (brushless dc) pancake type axial air gap motors. A benefit to designers, the hollow-shaft opens means to pass wiring, tubing, laser beams, or other mechanical parts through the motor's center. Maximum through-bore sizes are 0.25, 0,375, and 0.5 in., respectively, for the size 9, 12, 16 hollow-shaft motors available. Encoders, tachometers, and holding brakes are among optional features.
