True.
When a motor is turned on, electrical energy from the power source is supplied to the motor. Inside the motor, this electrical energy is converted into mechanical energy through the interaction of magnetic fields and current-carrying coils. This mechanical energy is then used to perform tasks such as rotating a shaft, driving a fan, or powering a vehicle.
However, not all of the electrical energy is converted into useful mechanical energy. Some of it is lost in the form of heat energy. This is due to internal resistances and inefficiencies in the motor. These losses can occur in the windings, bearings, and other components of the motor. As a result, a portion of the electrical energy is dissipated as heat, which contributes to the overall energy efficiency of the motor.
Therefore, when a motor is turned on, electrical energy is indeed transformed into mechanical energy, but it is also accompanied by the conversion of some electrical energy into heat energy.
