Single Phase electric motors have a capacitor connected in series with the run winding, therefore the motor is always drawing a constant current irrespective of mechanical load. When the motor is not under load this residual current is dissipated in the form of heat. Therefore Single phase electric motors should always be used at or near ‘full load’ so that the energy is converted into mechanical ‘work’ and not into heat.
