Integrated motor and resolver gets a slimmer profile

A smaller profile for the Mosolver from QuickSilver Controls means more applications for the device in tighter spaces. QuickSilver Controls extended its patented Mosolver (Motor + Resolver) technology into the compact 17 frame format. The integrated motor and encoder provides 32,000 counts of position information. The sensor is protected by the motor structure, does not need a separate housing, and is unaffected by dust or grease.


The smaller profile of the Moslover with the compact 17 frame format ensures that it can operate in smaller spaces while maintaining efficiency. Courtesy: QuickSilver ControlsQuickSilver Controls, based in Covina, Calif., has extended its patented Mosolver (Motor + Resolver) technology into the compact 17 frame format. The Mosolver sensor provides 32,000 counts of position information using a compact polyamide sensor coil placed within the stator, opposite the rotor. The sensor is protected by the motor structure and does not need a separate housing. Magnetic in nature, it is not affected by dust or grease.

The temperature range is limited by the motor ratings rather than by the sensor, which is inherently aligned to the motor, providing both position and commutation information. When combined with the SilverSterling controller, a compact, hybrid-servo system provides high-torque capability while eliminating low- and mid-speed resonances. The true closed-loop operation handles wide ranges of inertial loads.
