Why are DC motors used in elevators?
Answer:
DC motors are used in elevators because they usually have higher starting torque than AC motors.
This is especially important for high-speed elevators¹³.
DC motors when series connected (the armature and field coils) have a high torque at
low speed (including 0) which fits well for elevators, trains and traction purposes.
