IPM gearmotors that are small and run cool
IPMax (photo) is a line of lightweight, compact interior permanent magnet (IPM) gearmotors that are highly efficient with a wide synchronous speed range. IPM motors are suited for conveyors, fans and pumps, and are frequently used for factory automation, material handling, packaging and food processing. 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. IPMax gearmotors are 23% smaller than comparable IE3 motors, and run 24% cooler for longer lifespan, says the manufacturer. — Brother Gearmotors, Bridgewater, N.J.
