The correct answer is: B. low starting torque
A shaded pole motor is a type of single-phase induction motor that has two windings: a main winding and a shading coil. The main winding is connected to the power supply, and the shading coil is placed around part of the main winding. When the motor is turned on, the current in the main winding creates a magnetic field. This magnetic field induces a current in the shading coil, which creates its own magnetic field. The two magnetic fields interact to create a rotating magnetic field that causes the motor to turn.
Shaded pole motors are used in applications where low starting torque is required. They are often used in small appliances, such as fans and blowers.
Here is a brief explanation of each option:
- A. high starting torque. This is not the correct answer because shaded pole motors have low starting torque.
- B. low starting torque. This is the correct answer because shaded pole motors have low starting torque.
- C. medium starting torque. This is not the correct answer because shaded pole motors have low starting torque.
- D. very high starting torque. This is not the correct answer because shaded pole motors have low starting torque.
