Answer 3

An Electric motor is a machine which converts electric energy into mechanical energy. Its action is based on the principle that when a current-carrying conductor is placed in a magnetic field, it experiences a mechanical force.

Electric motors are broadly classified into two categories as follows:

1. AC Motors.
2. DC Motors.

Types of AC Motors: Classification Based On Principle of Operation:

(a) Synchronous Motors.

1. Plain

2. Super

(b) Asynchronous Motors.

1. Induction Motors:

(a) Squirrel Cage

(b) Slip-Ring (external resistance).

2. Commutator Motors:

(a) Series

(b) Compensated

(c) Shunt

(d) Repulsion

(e) Repulsion-start induction

(f) Repulsion induction

Classification Based On Type of Current:

1. Single Phase

2. Three Phase

Classification Based On Speed of Operation:

1. Constant Speed.

2. Variable Speed.

3. Adjustable Speed.

Classification Based On Structural Features:

1. Open

2. Enclosed

3. Semi-enclosed

4. Ventilated

5. Pipe-ventilated

6. Riveted frame-eye etc.

Types of DC Motors: Most common DC motor types are-

1. Permanent-magnet motors

2. Brushed DC Motor

a. DC shunt-wound motor

b. DC series-wound motor

c. DC compound motor

i. Cumulative compound

ii. Differentially compounded

d. Permanent magnet DC motor

e. Separately excited

3. Brushless DC Motor

4. Coreless or ironless DC motors

5. Printed armature or pancake DC motors

6. Universal motors
