FAQ

How is the rated current of three-phase AC motor calculated?

I=S/1.73UX0.8 is: apparent power divided by the square root of 3, 1.73, and then divided by the voltage X power factor 0.8

I am looking to use a dc motor to power a very small, high speed fan. I need it to equate as closely as possible to a 110v 1600 rpm 1/70hp ac motor. Any suggestions would be appreciated.

Go by the equivalent of torque in specific speed (example foot pounds)

I am looking for a device that would allow me to control how fast a AC motor spins. I am using a 110v AC motor that came off a air compressor. Can anyone help?

You need an electronic motor speed control. It varies the voltage and the frequency to change the speed. The ratio of voltage to frequency is maintained constant. Do a web search.

can u provide me the general equation for servo motor? thanks

Where is the specific purpose ? If it is used for measurement Generally Servo motors are magneto motors.In traction series , some place compound also used .

I'm trying to make a a Go-Kart running with solar panels and a wind generator. But i'm having problems trying to find a motor for it and i need one that would be fast. This would be used for a science project for my senior year in highschool and i'm trying to make something really good. Also i need some more i deas on how to make this.

Use an AC motor and a really, really long extension cord. Seriously, with AC you're going to need an inverter that will add weight and complexity. Go DC, use dry cell batteries (I use the backup for my phone/cable/isp router for bike accessories. light weight and decent capacity) The motor and controller are your big investments. Any rechargeable lawnmower motors that will work; you'd need a few? Good luck. I've been planning an electric trike for a while now.

and act as a brake or actuator? I realize an electric motor can act as a brake but can its position be locked solid?

Yes. An AC induction motor can be locked by introducing a sufficient dc current of proper polarity across two phases . This is a common way of preventing e.g.fan motors from windmilling backwards during idle periods on ,say. cooling towers. This application of DC current is also used as a braking technique for induction motors.

How can I slow down an 120 volt ac motor it's a drift drive buffer. It is about 3500 Rpms I want it to be around 2500. Would a variable speed drive work? I'm in an electrical class but did not get that far.

note it says DC motor, it means AC motor.. the circuit can be adapted for 120V ac and is a good starting point.

The motor is out of a dryer (240 VAC) so there is lint build-up in the motor's grease. The casing seems to be a cast iron that has been... connected... not welded, not screwed together. I see no way to get the case open to pull it apart. I can get it working properly for about 24 hours using generous amounts of WD-40, but the motor builds up some physical resistance after this time. I feel I need to clean the contacts, and relubricate the motor. I can see the contacts as the case only holds everything together, and does not fully enshroud the windings. What can I use to clean the motor without dissasembling it further, or how can I dissasemble the case (if you have come across this before you know what I mean). I am an apprentice electrician so I already understand the safty concerns of fixing an appliance.

the best way is to use an air hose of some kind and blow it out... dryer motors don't have any kind of lubricating procedures... when you spray wd40 to lubricate this motor you are creating a fire hazard by the flamable vapors from the spray... thats why there is no lubricating ports of any kind.. one thing i would concider is that you might have a bearing going bad on this motor, thats why it will run for awhile and then shut down...
