Can I rotate an AC motor spindle manually? When the power supply not given.?
most ac motors these days are contained in the compressor and really have no access, but yes in theory if you could get to the shaft, it would turn, if it had a shaft.
NO YOURE PLAYING WITH A ELECT. HY-BRED DONT PLAY w/ these it can start blow up or explode if you get stuck no if this is w/ you are working on stop its not worth it these things after you save a bit will doo the ?? just dont
Yes. In fact, when the motor is driven manually, it becomes an electric generator.
Yes, it should turn freely except for rare types that include a brake. It won't generate electricity - DC motors do that, not AC - but it should have very little drag.
