Which of the following single phase motors is relatively free from mechanical and magnetic vibration?

Which motor is relatively free from mechanical and magnetic vibrations? Shaded pole motor.

Which of the following is most economical method of starting a single phase motor?

The cost of the capacitor start method is slightly higher than the split-phase method but due to the high starting torque and high power factor, this method is the most economical method to start a single phase motor.

Which of the following single phase motor has highest efficiency?

4. Permanent-split Capacitor (PSC) motor:

  • In this type of motor, no centrifugal switch is required.
  • This motor has higher efficiency.
  • It has higher power-factor because of a permanently-connected capacitor.
  • It has higher pull-out torque.

What kind of universal motor is free from mechanical and magnetic vibration?

Which motor is relatively free from mechanical and magnetic vibrations? Shaded pole motor.

Which of the following single phase motor can be used for electric traction?

For electric traction, DC series motors are best suited. DC series motors and AC series motors are very much recommended, as they provide a high starting torque Nowadays three-phase induction motors are also being used.

Where are repulsion motor used?

A repulsion motor is a type of electric motor which runs on alternating current (AC). It was formerly used as a traction motor for electric trains (e.g. SR Class CP and SR Class SL electric multiple units) but has been superseded by other types of motors. Repulsion motors are classified under single phase motors.

Which of the following motors is used in mixers?

We use universal motors in mixer grinders. Universal motors can run both on a.c. and d.c. The universal motor works on the same principle that DC series motor works.

Which one of the following motor is a 1 phase AC motor?

The shaded-pole motor is the original type of AC single-phase induction motor. A shaded-pole motor is a small squirrel-cage motor in which the auxiliary winding is composed of a copper ring or bar surrounding a portion of each pole.

What are the types of single phase motor?

Types: There are a few different types of single-phase motors; some of these are two-valve capacitor, capacitor-start, split-phase, permanent-split capacitor, wound rotor and shaded-pole motors. Each type of motor has its own unique advantages and disadvantages.

What is a 1 phase motor?

What is a single-phase motor? A single-phase motor is an electrically-powered rotary machine that can turn electric energy into mechanical energy. It works by using a single-phase power supply. They contain two types of wiring: hot and neutral. Their power can reach 3Kw and supply voltages vary in unison.

How many types of single phase motor are there?

There are three types of single phase induction motors which are the shaded pole, split phased, and capacitor motors.
