Which type of motor does not require a starting switch or mechanism?

The shaded pole motor is designed with a specific construction that allows it to start without the need for an external starting switch or mechanism. This type of motor has a simple design, featuring a shaded pole that creates a rotating magnetic field sufficient to start the motor.

As a result, shaded pole motors are commonly used in applications where low starting torque is acceptable, such as in small fans and low-power household appliances. The absence of a starting mechanism simplifies the design and reduces the overall cost of the motor, making it a suitable choice for specific applications.

In contrast, other types of motors, such as split phase, capacitor start, and universal motors, require a starting mechanism to provide the initial torque needed to start the motor. Each of these alternatives relies on more complex internal components to achieve proper functioning during startup.
