A 6-pole motor turns at 1080 rpm when connected to a 60 Hz voltage source. Most nearly, what is the angular velocity of the slip? OA. 27/3 rad/s OB. TT rad/s OC. 27 rad/s D. 477 rad/s 4π

Q: The O smaller O larger the number of poles used in a stepper motor, the better the resolution

A: here we have to give relation between the number of poles and resolution.

Q: If the voltage is 400v its 3 phase its frequency is 50hz it has 4 poles per phase its running speed…

A: Step 1:

Q: At start the slip of an induction motor is equal to O 0.75 00 O 0.5

A: At starting the rotor speed of induction motor is zero. Nr=0 Let a induction motor with synchronous…

Speed control of motor

Speed control by DC motor-speed controller is required to realize variable speed drive. Whenever a motor drives a particular load, it is called drive, and variable speed drive refers to a load requiring variable speed. All this is obtained by a DC motor speed controller.
