The series 121-1 (2.1" diameter) permanent magnet DC motor is available to serve the industrial, instrumentation and automotive markets in either open-loop or close-loop applications. Rotor laminations are skewed to provide low cogging torque and no preferred rotor position. Standard catalog stall torque ratings are in the range of 60 to 180 oz-in, while no-load speed ranges from 2,100 to 8,000 rpm max. Encoders with line counts up to 2048 are available. Reliability is enhanced by long life, pre-loaded ball bearings. Special windings, shaft and mounting configurations are available to meet the requirements of OEM custom applications.
