Electric Motor
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 whose direction is given by Fleming’s Left-hand Rule and whose magnitude is given by F = BIl Newton.
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 Motor
Most common DC motor types are-
1. Permanent-magnet motors2. 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
