How a 3-Phase AC Induction Motor Works

In previous videos, we’ve mainly focused on how VFDs work and how they control a motor. This video will focus on the motor itself.

We begin with the basics of a 3-phase AC induction motor, one of the most common industrial motors.

Mike will give an overview of 3-phase power, how Faraday's law works, the main components of an induction motor, and the effect the number of stator poles has on the rated speed and torque of a motor. #Inductionmotor #3phasePower #AutomationWithDrive

This is a great 1000ft view of a 3-phase motor concept. Well done!

at 2:35 you say "apply the current across the stator" - this is incorrect terminology. voltage is "applied" while current "flows" as a result. but, otherwise it is a good explanation :)

Hello I would really appreciate it if you could help me resolve this issue. I have a 1000 rpm 160 kw rated 3 phase Delta connected ac motor hooked to an air compressor feeding an oxygen production plant. our phase to phase supply voltage is 380 volts. our maximum running load current at working pressure is 250 Amps. This motor failed as it was running for more than 10 years. Lately we demanded more continuous load due to high demand for medical oxygen effected by covid19 pandemic. I could not find a similar replacement available. However i found another German made motor with same mounting frame and shaft size and also 1000rpm at 50 Hz the name plate says: Delta connection 660 Volts - 260 Amps - 240 KW. my question is : if i supplied this motor 380V with same delta connection will it be able to give me 160 kw power? because its limiting design current is 260 Amps as it says . Thus if am assuming its rated power will be reduced proportionally to the reduction of supply voltage. i it is rated 240 Kw at 660 Volts is it true that it will become a 160 Kw motor under 380 Volts? I am also assuming it will not overheat as the current will not exceed its rated 260 A at my demanded compressor load. Please help me if you have a definitive answer without any speculations. Best regards
