FAQ

When I put freon in ac motor runs for 1 to 2 seconds

Wrong freon. Old system is probably full of air and cannot accept any freon, compressor bad and leaking etc. If you take it to an a/c mechanic he can change it to the new system. Big bucks though.

Everything is wired correctly, can hear the relay kick on when power is on but motor will not start

I have to make a few assumptions here since additional information is necessary to try and help you. I assume this is a single phase induction motor. Second, based on the first assumption, the motor may be wound with just a simple auxiliary winding to start the motor spinning or it may have one or two capacitors attached to it for improved starting torque and running performance. Third, I assume the motor windings are good. If you the motor humming when you energize it, but it does not spin, you may have an open circuit to the auxiliary winding. Try turning the motor shaft in the direction you want it to spin. Does it spin for you? If yes, the centrifugal switch supplying the auxiliary winding may be bad. Check and replace it if necessary. If your motor has one of more capacitors mounted outside of the motor case, check and replace them as necessary. If your windings are good the motor should work. Hope this helps, Newton1Law

one word answer?

You can spin that motor either direction until you are blue in the face, but you won't get enough to light a flashlight bulb. Electricity depends on a magnetic field and there ain't one.

I have a 1.5hp 220v 3 phase motor driven band saw. I need to run it on a 220v single phase system. The original single phase converter consisted of a 550uF capacitor supplying the third phase winding with the contacts of an NC relay in series with the capacitor. The coil of the relay is from the supply through a resistor to the third phase winding and dropped out when the motor came up to speed. A second 40uF capacitor is from the supply to the third phase winding and is the only capacitor that remains active when the relay opens up (motor is up to speed). I'm looking for a simpler and more reliable solution, as the present circuit is temper mental and old. Replacing the motor is a last resort. Is there a simpler capacitor type converter that can be designed? The saw is only operated intermittently for 10-15 minutes on time, 30-60 minutes off for an 8 +hour period, for a few days a month. It is used for a meat cutting band saw. Any sources, help or information would be greatly appreciated. Thank you.

Capacitor type converters do tend to be temperamental, but the circuit you have seems to be about as simple as they come. Rotary phase converters are generally considered much better, but are also much more expensive. Another option that may be practical due to the lowering cost of semiconductors, is a is a VFD inverter drive, while the name includes variable frequency you can just as well use it at a fixed speed. Just a couple weeks ago I installed 3 conveyors with singe phase to three phase VDF inverters (albeit wit smaller motor than yours) and they work flawlessly.

Here is the 3-phase AC motor Motor Description:Phase: 3H.P.: 1.0Amps: 2.8/1.4Volts: 200-230/460RPM: 1725Service Factor: 1.15I want to operate the above mentioned 3-phase 230volt AC motor with 12volt DC to 230volt AC inverter BUT I do not know if any such inverter exists in the market that can operate 3-phase AC motor? 1. If you know any such inverters, Please list them in your answers.2. If no such inverter exists in the market, then what is the solution to operate the above mentioned 3-phase 230volt AC motor with 12volt DC to 230volt AC inverter?3. Answers with details will be appreciated.

1 HP is 746 watts, so the motor will consume more than this. I'm sure there are inverters available to do this, but it would be better to use a higher input voltage (to reduce the current). Also you need to make sure the inverter can safely handle the motor stating current. This can be 5 or more times the full load current.

How to distinguish between DC motor and AC motor?

The difference between DC motor and AC motor is, of course, the different types of drive power, one is DC, one is communication.

Sometimes the fan will start. Other times it will just hum when I power it on. If I turn the power off and then manually rotate the fan a quarter turn or so, it will then start when I apply power. Does this point to bad brushes, a bad starting capacitor, or something more serious?

Hi, If the fan comes with a capacitor, try and replace it first. It's only about $10 or $20 dollars. If that doesn't work, then replace the fan motor. The capacitor works by changing the phase angle of the current going into the motor where there is an additional winding that helps the motor start by giving it more torque, then the capacitor cuts out mechanically. Hopes this helps.

It's a 1kW single phase AC pump motor with a 100v supply. This is for a theory question btw. :)

Depending on what type of motor you have, you can either adjust the amplitude of the AC sine wave or adjust the frequency of the AC sine wave.
