eMotors Direct’s stock of permanent magnet AC motors are for use in compressor, pumping, and air moving applications. Unlike the standard AC induction motor, PMAC motors have permanent magnets attached to or embedded in the rotor, which spins at the same speed as the magnetic field. Since the rotor matches the speed of the natural magnetic field, these motors have 15-20% less energy loss than the NEMA Premium Efficient induction motors.

Our permanent magnet AC motor category covers both Baldor designs and the three-phase SyMAX Permanent Magnet AC Motor by Marathon Motors. Available in fractional horsepower ratings up to 25 HP and RPM outputs of 1800 RPM @ 90Hz, 1800 RPM @ 120Hz, 1800 RPM @ 150Hz, or 1200 RPM @ 60Hz. Choose from a large selection of frame sizes and mounting options, and Totally Enclosed Fan Cooled (TEFC) or Totally Enclosed Non-Ventilated (TENV) enclosures.
