What are the characteristics of electric motor?

Electric motor speed-torque characteristics may be classified into three main groups:

  • Absolutely Hard (flat) Speed-Torque Characteristic: A characteristic exhibiting no change in speed with change in load torque. …
  • Hard Speed-Torque Characteristic: …
  • Soft Speed Characteristic:

What are the characteristics of 3 phase induction motor?

When three-phase balanced voltages are applied to the stator of an induction motor, a forward-rotating field is produced in the airgap. … With a symmetrical rotor, the resultant of the backward-rotating components is zero, whereas for an asymmetrical rotor the resultant is non-zero.

What are the characteristics of a dc series motor?

Characteristics of a DC Series Motors:

  • Speed-Current Characteristic:
  • Since on no load the series motor attains dangerously high speed, which causes heavy centrifugal force resulting in the damage of machine, series motors are not suitable for the services:
  • Torque-Current Characteristic:
  • Speed-Torque Characteristic:

Which characteristics of motor is called mechanical characteristics?

torque (N-Ta) This characteristic is also called as mechanical characteristic. From the above two characteristics of DC series motor, it can be found that when speed is high, torque is low and vice versa.

What does a motor do?

A motor converts electrical energy into mechanical energy. It is estimated that nearly half of the world’s energy consumption is consumed by motors.
