30070 Permanent Capacirot and Two Capacitor Motors

A capacitor start, capacitor run motor is basically a combination of a capacitor start and ___.

Permanent capacitor motor

It combines the high starting torque of a capacitor start motor and the efficient running of a permanent capacitor motor.

Which of the following is not a method used to adjust the speed of a permanent capacitor motor on a multi-speed fan?

Adding capacitors in parallel with the motor windings

Changing speed by adding parallel capacitors is not used; speed is usually varied by voltage or resistance.

Which of the following is an application of a permanent capacitor motor?

Fan and Blower

Permanent capacitor motors are ideal for fans and blowers because they run smoothly and efficiently.

Which of the following is a disadvantage of a permanent capacitor motor?

Low starting torque

These motors have low starting torque since they use only one capacitor continuously.

Which of the following is not a component of a permanent capacitor motor?

Centrifugal switch

Permanent capacitor motors don’t use a centrifugal switch because the capacitor stays in the circuit during start and run.
