Question

What is the mechanical power developed by a DC series motor is maximum?​

Answer 1

Answer:

What is the mechanical power developed by a DC series motor is maximum? Back emf is equal to half the applied voltage. Back emf is equal to applied voltage. Back emf is equal to zero.

Answer 2

Answer:

Here's the ans

Explanation:

The mechanical power delivered by DC motor is maximum at intersection of speed and torque curve at any load. The torque is generally negative slope and speed is positive slope. You can ask the manufacturer to share speed torque curve data. However, operating the motor at maximum power requires the mechanical load to exert sufficient torque on motor.
