  • What is the stator of a single-phase induction motor?

    The stator is the fixed part of the motor to which A.C. is supplied. The stator contains two types of windings. One is the main winding and the other is the Auxiliary winding. These windings are placed perpendicular to each other.

  • What is the difference between single-phase and three-phase induction motor?

    A 1-phase induction motor requires single-phase AC supply, whereas a 3-phase induction motor need a source of 3-phase AC supply for its operation. 1-phase induction motors produce low starting torque, whereas 3phase induction motors produce high starting torque.

  • What are the applications of single-phase and three-phase induction motors?

    The power factor of a single-phase induction motor is low as compared to that of a three-phase induction motor. Single-phase motors are mostly used in domestic appliances such as mixer grinders, fans, compressors, etc. Three-phase induction motors are mostly used in industries.

  • Why 3 phase induction motors are more suitable than single-phase?

    Three-phase squirrel-cage induction motors are widely used as industrial drives because they are self-starting, reliable, and economical. Single-phase induction motors are used extensively for smaller loads, such as garbage disposals and stationary power tools.

  • Why are 3-phase motors cheaper than single-phase?

    Because of this design, 3-phase motors have significantly higher efficiency at converting electrical to mechanical energy, and therefore lower operating costs. They are inherently self-starting, and because of their higher torque, especially during starting, they are ideal for heavy industrial applications.
