Can a garage door motor be connected directly to AC

Run it as it was originally powered in the garage or use something else ball-mills don t necessarily need a big motor L 0 Hard to answer you question without hands on the motor BUT I would expect the motor to be DC as it will have been reversed to open/shut the door and run from a relatively low voltage DC supply perhaps 30 volts or so...

What s causing your high motor current

Feb 23 2018 0183 32 Before drawing any conclusion check the line-to-line voltage If it is more than 10 above the motor rated voltage it could be the cause of the high full-load speed and possibly the high current An open rotor can cause a pulsation in the output torque of a motor as the open rotor bar passes under each phase of the motor winding...
