Which of the following is a common application for capacitor start motors?

Capacitor start motors are commonly used in applications that require a high starting torque to overcome inertia and get the motor moving. This makes them particularly well-suited for larger machinery, such as large blowers, which often need to start under load conditions. The capacitor provides an additional phase shift for the motor windings, allowing for a more robust start-up performance, ensuring that the motor can handle the initial resistance encountered.

In contrast, washing machines and small fans typically do not require as much starting torque, and they often utilize different types of motors, such as permanent split capacitor motors or shaded pole motors, which operate more efficiently for their specific applications. Computer hard drives require precision and minimal vibration, so they typically use brushless DC motors or stepper motors instead of capacitor start motors.
