ESP-OL Open Shaded Pole Motors 50-75 Watts Output

The ESP-OL style fan motors represent the highest power outputs available in the efficient eccentric wound shaded pole design.  The ESP design exhibits a higher electrical efficiency than the typical shaded pole motor.

The 4-pole unit bearing motors are available in three outputs – The ESP-OL50 rated at 50 watts (1/15 HP), the ESP-OL60 rated at 50 or 60 watts (1/12 HP), and the ESP-OL75 rated at 75 watts (1/10 HP).  Standard performance tests reveal all models attain an electrical efficiency of 39% when tested at 1600 rpm.
