Q: I've seen on facebook page of some technical institute that Tesla was NOT the first to build the AC motor, do you know who was first then?: 3 PHASE synchronous motor was made first by Friedrich August Haselwander in 1887. 3 PHASE cage induction motor was built first by Michael Dolivo-Dobrowolsky in 1889

Q: What's the difference between an AC motor and a direct current motor?: The continuous use of DC motor is short, for example: DC motor in use for 60 minutes, 10 minutes to rest, let the motor off heat, unstable power output, power consumption is based on the weight of the user to decide, but less noise.AC motor used long, can be dozens of hours of continuous use, and the power output is stable, the noise is a little larger.

Q: how do i run a .3 A 120 v ac electric motor with dc. how do i know the rate of revolutions? and how do i overclock it?: As Percival said, speed is a factor of Hertz (frequency). If you plug the motor into a regular AC outlet, it will run the speed it was designed to. If you want to be able to control the speed, you would have to be able to control the frequency of the AC you are supplying it. To do that, you can do like Percival suggested and connect various capacitors across the AC input or buy a VFD. VFDs (Variable Frequency Drives) are a bit more pricey. And to be quite honest, I've never seen a single-phase VFD for 110volts. You can find capacitors of various values at your local Radio Shack.

Q: Technician came into my house and said that the capacitor and FASCO York Exhaust Inducer Motor 7021-9428 702110300 needs to be changed.I bought these two items,changed capacitor only and everything is working.that motor is on the roof inside of the metal box.It looks like this motor just cools all the electrical inside.So I connected old motor back but I could't check if it works or not.If anybody knows how can I check if it rotates or not please let me know.If it works I could save some money.Thanks.: You are either misunderstanding the components or not using the proper wording. It appears to be a bit of each. Please repost your question with specifics. An exhaust inducer is a component of a heating system.

Q: Can a function generator be used with ac/dc motor to increase or decrease its frequency?: With an AC only motor if the function generator is connected to an amplifier yes it can. If it's a AC/DC brush motor like in a vacuum cleaner you can just use a simple control circuit. Look up triacs and light dimmers.

Q: What about the capacitance of the AC motor?: A little bit, that's OK. If it's big enough, it's easy to burn the motor. You can try it yourself and switch on the new capacitor for a while. (nothing is less for a moment) and see if it is not immediately fever, if it is, then you still use the capacitor motor much of it, but I think you'll change a big try the same as before

Q: What's the function of carbon brushes for AC motors?: AC motor brush: brush effect can be used for DC motor or AC motor commutator or slip ring, as sliding contact body import and export current, its thermal conductivity, and good lubrication performance, and has certain mechanical strength and direction of the spark of instinct. Almost all motors use carbon brush, which is an important component of the motor

Q: other?: Some of the largest AC motors are pumped-storage hydroelectricity generators that are operated as synchronous motors to pump water to a reservoir at a higher elevation for later use to generate electricity using the same machinery. Six 350-megawatt generators are installed in the Bath County Pumped Storage Station in Warm Springs, VA USA. When pumping, each unit can produce 563,400 horsepower (420,127 kilowatts).

Q: AC motors have no commutators and are driven by alternating magnetic flux. How can AC motors be controlled to one side, and how to realize positive and negative turns?: A sinusoidal voltage with a lead of 90 degrees or a phase of 90 degrees after a large capacitor is generatedAnd the original voltage can form a set of voltage difference of 90 degrees phase,.2 group voltage together can control its directionIf it's 90 degrees ahead, it's turning right. Then it will be reversed after 90 degrees

Q: it is small powerful motor and light i wanna use it as a motor for my RC plane any help!!!: If your motor is universal,one with armature and commutator segments and carbon brushes,it can run on dc power, but, if it isn't, your motor won't run on dc power.
