Q: What is RC Motor ? Is it AC or DC or Both ? What are its advantages Disadvantages ?What are its industrial applications ?thanks: An RC motor is a d.c. motor used in radio controlled models.

Q: Or is it just me?: There is no AC motor on any car, What the heck are you talking about? that's why you received no answer! You don't even say what year it is, Are you talking about A/C System? The compressor? I advise that you rephrase your question

Q: what is deference between PMSM and AC Servo motor?: PMSM means permanet magnet synchronous machine. An AC servo motor could also use permanent magnets, but it doesn't have to.

Q: I noticed that most elevators are powered not by an electric motor, but by an electric motor-generator set. Does the generator really put out enough current to make up for the friction losses?Or is the generator used for powering lights and stuff? If so, why not use inverters or some smaller, cheaper means of creating a smaller current for the lights?: That was the old way of powering the elevator. They needed to smoothly start and stop the elevator, and at the time, there was no way to control an ac motor with a variable speed. Only dc motors could start and stop smoothly based on the amount of current available. So the solution was to couple the ac motor, running all the time, to a dc generator whose field could be varied thus controlling the output current. This current was sent to the dc hoist motor, lifting the elevator smoothly, the operator controlling the field current of the generator to control elevator speed. Lights were never controlled by the generator, they just ran off the available ac supply directly. The generator does put out enough to overcome any friction losses in the system, but notice that there are counterweights on wire ropes to counterbalance the elevator car. Therefore, not as much power is used to raise and lower the elevator.

Q: I was curious if I rewired the AC motors on both the squirrel cage fan and outdoor unit to DC, and hooked solar panels directly to with battery backup, would that be anymore efficient than converting to AC?: Don't AC and DC motors differ quite a bit in design? Is this even possible short of building a new motor?

Q: Can I rotate an AC motor spindle manually? When the power supply not given.?: 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

Q: What different types of AC and DC motor is there?I am also interested in the different features and characteristics of each, such as starting torque, as well as speed and loaddo you have any information or links to websites showing construction? or typical applicationThankyou for your help, I will happily give 10 points to the best answer!: (a) Synchronous Motors. 1. Plain 2. Super (b) Asynchronous Motors. 1. Induction Motors: (a) Squirrel Cage (b) Slip-Ring (external resistance). 2. Commutator Motors: (a) Series (b) Compensated (c) Shunt (d) Repulsion (e) Repulsion-start induction (f) Repulsion induction

Q: how do i change the rotation on a g.e. 5kc49tg1255x ac motor?: if it is a single phase motor,you cant. a 3 phase motor can be reversed by swaping any 2 of the 'hot' wires

Q: why choke or du/dt filter is used with vvvf drive of ac. motors?: i assume you mean a variable frequency drive. there are many applications that use a choke or the other filter you were talking about, either for a conveyor system that moves heavy pallets without having the pallets tilt over or to a roller coaster that monitors tension so peoples heads don't start falling off.
