What are the torque characteristics of a shaded pole motor?

• A. High start and high running torque
• B. Low start and low running torque
• C. High start and low running torque
• D. Low start and high running torque

Answer: (B)

The torque characteristics of a shaded pole motor are characterized by both low starting and low running torque. This type of motor is designed primarily for applications requiring a low level of power, such as small fans or other small appliances. Shaded pole motors achieve rotation through a magnetic field that rotates in a distributed manner along the stator. This design results in a comparatively weak torque when starting, meaning that the motor struggles to begin turning from a standstill. Once in motion, the running torque remains low, making these motors less suitable for heavy-duty applications. The simplicity of their design, along with their cost-effectiveness, makes shaded pole motors common in less demanding environments, but their limitations in torque output define their operational capabilities in commercial and residential applications.
