Hello,
In Vector control of induction motor, stator currents iqs (torque component of stator current) and ids (field component of stator current) are controlled separately just as in the case of a separately excited DC motor by keeping either of the current components constant.
My question...
Hi Guys,
As is aware, an induction motor acts as a generalized transformer. So whenever rotor MMF is created on load condition, immediately a balancing current flows in the stator windings to neutralize the rotor MMF by transformer action. However, if we assume the rotor conductors to be purely...
Hi guys,
The purpose of this post is to understand the actual phenomenon behind torque production in eddy current motors. This query is based on theoretical principles of torque production in AC motors.
Consider a simple eddy current AC motor with a disc type or cylindrical rotor (Watthour...
Hi guys,
Can someone please provide graphical representation (waveform) of emf induced in coil due to a bar magnet spinning perpendicular to axis of coil as illustrated in attachment.
Thanks...
Hi Guys,
It's common knowledge that Single phase capacitor start induction run motor keeps running on single winding even after start capacitor is disconnected by centrifugal switch. But in practice, table fan motor stalls and hums when I disconnect starting capacitor when fan motor reaches...
