What are the different classifications of load and how they affect the motor selection?

The three main electric motor load types are: Variable-torque loads – eg fans and pumps where the speed varies. With this type of load, reducing the speed of the motor by even a small amount can save a lot of energy. Constant-torque loads – eg conveyors, screw and reciprocating compressors, and crushers.

What are the important factors to be present in order for a DC motor work?

When selecting a DC motor for a given application, two factors must be taken into consideration: 1) The allowed variation in speed for a given change in load. 2) The allowed variation in torque for a given change in load.

How does an induction motor start?

A three-phase Induction Motor is Self Starting. When the supply is connected to the stator of a three-phase induction motor, a rotating magnetic field is produced, and the rotor begins rotating and the induction motor starts.

What is synchronous speed?

: a definite speed for an alternating-current machine that is dependent on the frequency of the supply circuit because the rotating member passes one pair of poles for each alternation of the alternating current.

What are the parts of induction motor?

The stator of the three-phase induction motor consists of three main parts :

  • Stator frame,
  • Stator core,
  • Stator winding or field winding.


What are the components of load torque?

Components of load torques:

  • Friction Torque (TF) The friction torque (TF) is the equivalent value of various friction torques referred to the motor shaft.
  • Windage Torque (Tw) When a motor runs, the wind generates a torque opposing the motion . …
  • Torque required to do useful mechanical work ( Tm)

What determines the method of controlling motor speed?

Thus, the speed of a DC motor can be controlled in three ways: By varying the supply voltage. By varying the flux, and by varying the current through the field winding. By varying the armature voltage, and by varying the armature resistance.
