Q:i would like to get one that can be the same model number and everything: this is the one that came off my AC - A.O.: go to a real supply house with your old motor and fan and start cap and don't leave without the new start cap its needed and cheap.

Q:What are the similarities and differences between brushless DC motor and AC brushless motor?: The so-called brushless, no brush, is not to rely on this kind of motor brush armature current to change the polarity, and generally by the position detection device, such as Holzer, such as photoelectric encoder position detection, and then according to a control method, according to the polarity of the armature current change of position signal.

Q:Even when I put the AC 78 the house will get really hot..when we check the AC..the motor is frozen. We then have to turn it off for it melt and the ac will work again until it freezes. Any suggestions as to what can be wrong, what parts need to be replaced?No we don't need a new ac...: your freon is low,sounds funny, you would think it would be the other way around.get someone to put freon in it.

Q:I have an electric throttle with three wires ( black, red , green) and I want to know how to connect it to my electric motor and battery which both have only a black and red connector. How do I were it up so that I could control how fast the motor goes with the throttle .? Thank you .: A DC motor's speed is controlled by the voltage applied, an AC motor's speed is controlled by the frequency of the power applied and the number of poles in it's windings. The 1977 Urba Electric car featured on Mechanix Illustrated had the accelerator control the gear ratio of an industrial CVT similar to the ones you'll find on a small portable cement mixer thereby automatically both throttle and regenerative braking without complex electronics. The usual approach to a DC motor control is what's called a chopper control which basically connects the power some of the time, the capacitance of the system and perhap of a capacitor, averages the voltage out to the desired levels. As you have to invert the DC to produce AC for an AC motor, the speed control is done in the inverter. The newer brush-less DC motors are really more like AC motors with a built in inverter, designed to function as if it is a DC motor. Unfortunately, regenerative braking takes a lot more cleverness. You should probably just buy a controller kit from one of the many EV conversion companies.

Q:Is it an universal motor which works on ac or dc voltage,how does it work,speed regulation rheostat foot pedal,I mean can someone explain me technically how a sewing machine motor works,and how to connect it back after rewinding,thank you.: Sewing Machine Motor

Q:I made a three axis CNC router with three CD drives. I was going to make a stepper motor controller board for the CNC but I noticed that the motors are NOT servo motors instead they are hobby motors(the motors with two wires) So is there a schematic anyone knows of that controls a hobby motor with a parallel port? I WILL PICK A BEST ANSWER!!! thank you!: If you want this router to work at all you need micro stepping and cheap easy plans don't offer this. The plans that do end up costing a lot in parts so it's better to just buy a kit. If you have money you can get good controllers from rutex and gecko drives.

Q:What is the low power factor of AC motor in no-load operation?: First, if it is a single-phase motor, its power factor is equal to the three-phase, then it is low, in this case, the load is unbalanced

Q:What's the difference between a three-phase AC motor and a DC motor?: AC motor shell usually made from cast iron, only as a function of protecting and supporting the motor; and DC motor shell is made of steel or steel, except for the protection and support of motor, or part of the magnetic circuit;

Q:the motor came from a floof buffer it has a 3 gear planetary for tourq. I want to slow the moter down so I can bend rodiron: There is two ways of changing the speed of an AC motor. The first is a gear box, which you stated you don't want to deal with. The other, and also expensive, is a frequency drive. This actually changes the incoming AC into DC then back to a AC that can be changed in frequency. This set up is used a lot in commercial AC applications.

Q:Main structure of AC motor: Rotor: rotating shaft: Acting output torque. Rotor iron core: the silicon steel sheet which is insulated from each other is pressed on the rotor shaft, and there is a groove on the outer circle of the silicon steel sheet. For embedded rotor winding. Guide slot. Rotor winding: there are two kinds: one is squirrel cage, the other is winding type.
