Hello,
I have a 3 Phase Induction Motor 15kW, 415V, 26.4A
Approx DC Resistance of a single Stator Coil is 1 Ohm with my DMM
As an experiment I want to apply a low DC Voltage & Current to a single Phase of the stator windings to see the braking effect.
The motor is not connected to mains power & will not be connected to mains power only a suitable DC supply for a single stator winding.
My question is, how much DC Current can I apply to a single winding safely without damaging the windings.
Obviously if I apply 12V Dc the winding will see 12A or 24VDC will be 24A but I am not sure how much DC Current the windings will take.
Is there a way I can work this out or get some advice please.
I read on the internet that a DC Current applied to a single Phase can be 2 to 3 times the maximum Amp rating of the motor, but this seems to be worthy of further questioning?
Many Thanks
