Shaded-pole motors are used to drive devices that require low starting torque; hence are ideal for low-power, continuous-duty applications.
These motors are very suitable for small devices like relays, fans of all kinds, etc., because of their low initial cost and easy starting.
The power factor of a shaded pole induction motor is generally quite low. They often have a power factor of around 0.5 to 0.6, which is considered low. The low power factor is due to their design, which includes a small and non-optimized core and winding arrangement, leading to poor efficiency and a lagging power factor.
