what will be happened when a single phase motor is supplied
by the dc supply
Answer Posted / alan jenkins
In a nutshell it depends what type of motor it is, some motors with a wound rotor and brushgear will run on AC and DC, however AC induction motors will not rotate, the DC current will have a locking effect on the rotor, hence DC injection braking (anyone heard of that ?)leaving a DC current on these motors for any length of time will heat up the windings.
