| Q. |
What is the condition for the steady-state operation of the motor? |
| A. | load torque > motor torque |
| B. | load torque <<<< motor torque |
| C. | load torque = motor torque |
| D. | load torque < motor torque |
| Answer» C. load torque = motor torque | |
| Explanation: according to the dynamic equation of motor, load torque must be equal to motor torque so that motor should run at a uniform speed. if load torque is greater than motor torque, the motor will fail to start and if load torque is less than motor torque, the motor will run at a higher speed which can damage the shaft of the motor. | |
