Powertec Industrial motors offers a wide selection of versatile brushless DC motors including variable speed motors. These DC brushless motors use permanent magnets made ofceramic ferrite bonded to the rotor to produce the magnetic field. TENV motors have high horsepower in relation to a small frame size with a range from 0.25 HP in a NEMA 42 frame to 100 HP in a NEMA 320 frame. DPFG motors also have high horsepower in relation to small frame size with a range of 5 HP in a NEMA 180 frame to 300 HP in a NEMA 320 frame.
