Brother Gearmotors -

IPMax gearmotors are designed to be lightweight and compact. The series incorporates magnets embedded within the rotor as opposed to on the surface. No copper losses are experienced in the rotor, and considerably less copper losses occur in stator winding. The gearmotors can operate fanless up to 1 hp and do not require encoders for sensor control. When stopped, a servo lock feature holds the motor in position.
