iMotor Shaded PolePSC
The iMotor refrigeration motor uses less wattage to
achieve the same airflow as a shaded pole motor,
so it produces less heat. Fewer BTU’s in the system
means less work and wear for the compressor for
even greater savings.

Less efficient shaded pole motors are often used in
original equipment to cut costs. While they do allow
some small savings in purchase price, the savings
are quickly eaten up in electric bills at todays high
power costs.
