    No voltage from generator when neutral and ground connected together

    Motor lost one feeding phase

    What would be the current of the 3-ph AC motor, if it lost one feeding phase? The load, efficienty and power factor (theoreticly would say stay) constant.

    Hi! Have any ideas how to make reverse of rotation of one phase motor, which have two windings - one for acceleration (only for start), and second one - for work? I think it is connected with windings. Thanks in advance!

    Heating of motor by using frequency converter

    For checking of operation of frequency converter (4kW 3 phases 400V)we use 0.75kW motor. Unfurtonately motor heats more than it could be. The frequency converter on my opinion was programmed correct. The rated current of the motor is 2.3A, but measurings shows that it is 3.2A. Is this...
