Factor affecting the efficiency of Motor


Factor affecting the efficiency of the Motor

Main factor which are affect the motors efficiency is as below.
·         Speed of Motor
·         Type of motor
·         Load
·         Temperature
·         Age of motor
·         Capacity of Motor
·         Rewinding of motor.

Speed of motor

·         Generally high speed motors are more efficient then lower speed motors.

Type of Motor

·         What is type of motor is affect to efficiency.
For example- Slip ring motor is less efficient then Squirrel cage motor.

 Load

·         If loading is very less or high then rated load then is may reduce efficiency of motor.

Temperature

·         Temperature is inversely prepositional to resistance so at higher temperature there will more losses across And temperature also effect other parameters like on magnetic circuit , expansion of marital etc.

Age of Motor

·         After some age of motor efficiency can decrease.

Capacity of Motor

·         At rated capacity motor give good efficiency

Rewinding of Motor

·         If motor is rewound than its efficiency is decreased.
