Which motor should not be started on no-load? Correct Answer DC Series motor

No-load speed of the DC motor is very high, it’ll create a dangerous situation and the centrifugal forces will destroy the armature and may harm the personnel. As, flux is inversely proportional to speed, speed will be infinity by calculations.
