Shaded pole cast iron unit bearing motors

Shaded pole cast iron unit bearing motors

Our shaded pole cast iron unit bearing motors are primarily used in commercial refrigeration applications, both evaporator and condenser, but can be used in any application demanding dependability with output ratings between 2 – 25 watts.

With over 60 years of experience our patented unit bearing motors provide our customers with years of durable, problem-free operation.

  • Voltage: 100, 115, 200, 230, 277, or 460 V
  • Output: 2 – 25 watts
