Answer: A
Share your understanding of this question with the correct explanation.
The answer is A. Series motor.
A series motor is a type of electric motor in which the field winding and the armature winding are connected in series. This means that the current flowing through the field winding is the same as the current flowing through the armature winding.
When a series motor is started on no load, the current through the field winding is very high. This produces a very strong magnetic field, which causes the motor to spin at a very high speed. This high speed can cause the motor to overheat and damage the windings.
Shunt motors, compound motors, and brushless DC motors can be started on no load without any problems.
