SOURCE: is posible run a single phase electric motor from

It is indeed possible to use ONE Phase to run a motor, You simply use One Phase and Neutral. BUT ONLY if the 3 phase is Double, more or less, the required usage Voltage, EG: 440 3 phase, will be OK, for 220 single phase, . But 220 3 Phase,will not run a 240. single Phase. So in your case is suspect not, it really will do no harm to try though. it just wouldn't work, if not enough "juice", be careful.

SOURCE: wiring diagram for electricmotor with capacitor

I do not have a diagram for you, but depending on the motor, I can tell you a couple of things. 1. All capacitors are wired in series with the start winding. Most multi-speed motors, that require capacitors, have two brown leads, along with the motor winding leads. If this is the scenario, then just connect line power to neutral and the speed you wish to use, and connect the two brown leads, one to each side of the capacitor. Hope this helps.

SOURCE: wiring diagram for electricmotor with capacitor

On most motors the wires with the tabs are connected to the capacitor (usually brown). White wire is neutral and color wires are speeds.

SOURCE: I am working with a Dayton 2YU39. The name plates

Hi,
Here's what I think but you will have to check it out...
The fan motor in the 39 heater is a 120V fan there fore it cannot be hooked to the 240 which potentially could have the high (wild) leg as one of the fan legs...
The 240V 36 unit probably has a 240v fan motor....
Now if you were to make sure that the leg that fed the motor was a 120V to ground leg then you will be okay...
Hope you understand where I was going with this...

How many amps in the Vision Fitness T9500 HRT Treadmill


it is a 3 horsepower motor, but no amperage specified. The review does say this model has drawbacks.
Vision T9600 HRT Comfort Treadmill review

However, I found this, so 23 to 28 amps based on a 3HP motor.

Note: the following table contains approximate full-load currents for motors of various types, speeds, and frequencies. Variations of ±10% may be expected.

I NEED TO REWIRE A DOERR LR24684 ELECTRIC MOTOR,ITS 1/2 HP, RPM 1725 115 volts to a metal lathe AND ON SWITCH IT'S WRITE- FOR IN DOWN IN CENTER STOP AND UP REV -I SEARCH TO CONNECT THIS...


Motor terminal box sometimes has a connection diagram inside the lid.

Basically a single phase induction motor has a run winding and a start winding and to reverse the direction the connections to one winding, usually the start winding, must be reversed and that is the function of the lathe switch.

Single phase motors are easily damaged and so if any doubt exists I strongly suggest you ask a motor specialist for assisstance.

I'm installing a 8NE-L , 1HP pump . How far can I run my 12/2 wire for 110 volt application?


The FLA (Full Load Amps) for a 1 HP single phase motor is 16 amps at 115 volts. 5% is the maximum allowable volt drop from the main electric panel to the pump per NEC (National Electric Code). When these values are plugged into the volt drop formula, such as this one:
http://www.nooutage.com/vdrop.htm
90 feet is the maximum allowable distance for a #12 copper rated at 75 degrees C.

I have a 3 phase electrical motor for my air compressor, How would i connect this from the air compressor pressure switch and towards the electrical source 120V? (for low volt)


If the electrical 120 volt source is single phase, the only way to run this motor is with a single phase to three phase converter. Best to sell the three phase motor and obtain a similar horsepower 120 volt single-phase capacitor-start motor (1750 RPM) for the compressor. You would also require a 3-phase pressure switch for use with the 3-phase motor. Hope this helps!

The TWO Black Wires are Phase and neutral and it's irrelevant which way they go on the motor, the Other is the earth and that MUST connect to the case.
Black, L1 & L2 the other green EARTH.
115 or 120 doesn't matter

The motor itself should have a sticker which describes the wiring for 115. It is a small change involving a single wire moving from one pole to another inside the motor starter cap (the bump on the motor itself).
