A. the direction of the rotating field is opposite to the rotating direction of the rotor B. rotor current is bigger than nominal current C. the direction of the induced torque is opposite to the direction of the rotating filed D. the direction of the induced torque is opposite to the rot...
awhen a full line voltage is supplied to start a three-phase induction motor used for driving a hoist,the motor starts suddenly, and due to the force of shocks developed caused by starting of the motor, a load suspended by the hoist is caused to swing resulting in a very dangerous ...
A 3 phase, 5 kW induction motor has a p.f. of 0.75 lagging. A bank of capacitors is connected in delta across the supply terminals and p.f is raised to 0.9 lagging. The kVAR rating of capacitor connected in each phase is kVAR.

A 3-phase induction motor that is delta connected and has a supply voltage E_(o) of 400 V at 50 Hz . An equivalent circuit of one phase of the generator is shown in Figure 1. Assume that the input voltage (E_(...
I'm trying to use the vesc for a three phase induction motor, but when a set it up, one of the three phase doesn't seems to work at all. So I get too output from the other phases phaseshift by pi. I don't really know if this is because of a shortcircuit or if it's a co...
The original control board would include a rectifier, smoothing and a three phase H bridge style driver, to create a three phase power output with variable frequency and duty cycle. The motor also has a tachometer on the back that the control board would use to monitor the sp...
In order to avoid lower efficiency, poor power factor and lower torque density, the airgap length of a three-phase squirrel cage induction motor (SCIM)should not be designed very large. On other hand, the distortion of airgap flux density distribution can be minimized by enlarging the airgap...
