Significance of back emf in dc motor hindi
WebA motor is a device which converts electrical energy into mechanical (kinetic) energy. A DC motor runs on direct current (DC), that is, current that only flows in one direction. When the DC battery is switched on, current flows through a coil, making it a current-carrying conductor. The coil then experiences a motor force due to an external ...

Significance of back emf in dc motor hindi
Did you know?
WebThis emf, known as the back emf, acts against the applied voltage that's causing the motor to spin in the first place, and reduces the current flowing through the coils of the motor. At the motor's operating speed, enough current flows to overcome any losses due to friction and other sources and to provide the necessary energy required for the motor to do work.
