What are the characteristics and function of electric motor?

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 is the characteristics of motor?

Starting torque – the torque produced at zero speed. Pull-up torque – the minimum torque produced during acceleration from standstill to operating speed. Breakdown torque – the maximum torque that the motor can produce before stalling.

What is the function of electric motor?

An electric motor is a device used to convert electricity into mechanical energy—opposite to an electric generator. They operate using principles of electromagnetism, which shows that a force is applied when an electric current is present in a magnetic field.

What is electric motor and its principle?

The electric motor works on the principle of magnetic effects of current. Its principle is when a rectangular coil is placed in a magnetic field and current is passed through it, the coil rotates as a result of the forces acting on the coil.
