TECO AC Motor High Voltage

Q: From what I remember about AC motors, one cannot lower the voltage to slow it down- it must be the frequency that is lowered. However, I have an AC wall fan which slows down when the voltage in my house drops. Whenever a microwave or similar high-current load is on the voltage drops slightly and I always notice the fan motor slowing or speeding up when the load turns on and off. Why is it doing this? I am assuming that it is not good for the fan but seeing that it has been running this way for years it must not be that detrimental to it...: AC motors as the name implies is run using AC/alternating current.. this is best represented by a sinusoidal graph with time in the horizontal axis and voltage or current in the vertical axis.. motors uses the current to produce power which drives whatever it is that's attached to the motor.. power is directly proportional to either voltage or current.. because of this, low voltage/current produces low power and vice versa.. this is the reason why your fan slows down when voltage drops..

Q: I'm a web developer, I have this project right now involving a search engine for motors I want to know parameters, so far these are what I have:ac/dcphase (redundant? eg. 3phase = ac ?) voltagerpmtorqueefficiency It's like this, a person designing a building might need motors for aspects such as ventilators, elevators, motors that open the elevator door, etc... So if you were looking for motors what are you interested in? I'm also not sure what the power output units are... for example one page for single phase said 0.08, is that... I don't know what is 1? A horse power? Ahh it is horse power, I found this line of specs here for an example motor .08HP,1725RPM,1PH,60HZ,42,3310L,TEFC,F1and the number 42, what is that for?: PS Note that there are standard no-load RPM ratings, but the full-load ratings on the nameplate are anywhere from 1 to 5% less than the no-load speeds and rarely more than 5% less. For 60 Hz the no-load speeds are 3600, 1800, 1200 and 900 RPM and rarely some values less than that. There are standard horsepower values like 1/4, 1/2, 3/4, 1, 1-1/2, 2, 3, 5, 7-1/2, 10 15, 20, 25, 30, 40, 50, 60, 75, 100, 125, 150, 200 and so on.

Q: easy to understand explanation would be nice: ac motors use alternating current. polarity changes amny times in a second. rotates in one direction specified. dc motors change the direction of roatation with change in polarity

Q: If we will supply 220VAC to a DC Motor of rating 220VDC.: A universal motor is a dc motor modified to operate on AC. There are different types of DC motors. A permanent magnet dc motor will not work with a AC supply. Both series and parallel wound field dc motors have windings for the field. Since in AC both the armature and the field will change polarity at the same time the motor will turn if AC is applied. The problem with a DC motor not made for AC is that the core of the field may not be made of laminations since there would be no eddy current induced in it when supplied with DC. When AC is applied eddy current would be induced in the core causing power losses and extra heating. A universal motor has a field core with laminations.

Q: What kinds of AC motors are divided into?: AC motors are usually divided into AC generators, AC motors and synchronous regulators according to their functions.AC motors are divided into two major categories: synchronous motor and asynchronous motor.

Q: I have a 90v DC electric motor I would like to run with 110v electricity. It was running off 110v when it was inside a wheel balancer. The motor came out of a wheel balancer and I need it for a specialized fan application. What kind of converter do I need to not only run it with 110v, but also make it variable speed? Any suggestions?: 90v Dc Motor

Q: If my old AC motor rpm was 850, what damage will a 1050 rpm motor cause?: Context? It depends on what it's driving. But we don't know that, do we? Tell us more and we can tell you more.

Q: ac motor to ac generator?: No. An ac motor has a solid stator. You would need a coiled stator in order to inject current.

Q: I am working on a variable frequency drive for an ac motor what parts do i need?: Not enough information! If you have a drive and a motor you have all the parts you need. Hook it up and program the thing.

Q: What's the difference between:1) AC motor2) DC motor3) Induction motor4) Permanent magnet motorAnd is there such a thing as a DC induction motor?: The okorder /
