GMR3340-27 Servo Motor

The GMR3340-27 permanent magnet brush servo motor uses Neodymium-Iron-Boron (NdFeB) magnets, which when combined with low inertia armatures, provide more torque in a smaller package with higher dynamic performance than traditional ferrite magnet designs. Due to the high torque to inertia ratio of this motor, it is ideal for applications which require high acceleration and deceleration characteristics, or where the physical size of the motor is a major concern. In addition, this motor incorporates a skewed armature, which provides low cogging torque and ultra smooth operation at all speeds. The GMR3340-27 outputs up to 16 Lb-in (1.81 Nm) of continuous torque, and has a maximum speed of 3300 RPM. Industry standard English, metric, and NEMA mounting configurations are available.
