Shaded pole motors are a simple, low-cost type of single-phase AC induction motor. They use a single main winding and a 'shading' coil that creates a small starting torque to enable the motor to begin rotation. The shading coil consists of a simple copper ring that produces an opposing field to that of the main winding, resulting in a rudimentary approximation of a rotating magnetic field. Because the phase angle between the main winding and the shading coil is small, starting torque is limited, and both performance and efficiency are low overall compared to other motors. Shaded pole motors are the most straightforward and economical HVAC motors on the market. Their relatively low torque, noisy operation, and low efficiency mean that they are typically limited to driving small fans in refrigerators and freezers.
