SDS Series Spindle Motors The new SDS Series spindle motors have been specifically designed for digital drives. They offer a sensible increase of power together with wider rated power speed range. The compact and rugged design makes these new motors ideal to equip machine tools where the high dynamic performances match the need of limited weights and dimensions with high reliability and the absence of vibrations. Main characteristics * Outstandingly smooth rotation * Rigid and compact build * Windings protected against overheating * High overloadability * Lower acceleration and deceleration times * Possibility of working as axis C through the integrated digital transducer for detecting speed and position * Assisted ventilation * Degree of protection IP54 * Degree of vibration: S * Shaft/flange coaxiality: R * Execution with star and delta/star windings * Hollow shaft option for circulation of coolant fluid for the tools * Constant power feed from 1500 rpm * SR balancing degree, that is certified with a test on each motor.
