AC motors are typically phase driven by the cycle of the mains, and a 50Hz motor running on 60Hz power wouldn't draw enough power to make a full partial rotation on a single power cycle - it'd run faster than it's made to, in a similar stress state as a "starting" electric motor, wearing out the components much faster and perhaps outside of their tolerances. Open the connection box and see if it has 3, 6, 9, or 12 wires. A 208V rated motor should not be run on 240V, nor should a 230V rated motor be run on 208V, motors rated 115/200-230V or 115/208-230V are fine either way, older 3Ø motors rated 220/440V will be fine on either a 208 or 240volt supply when connected for lower voltage. The pump is 2 wire, using the 2 120v legs. A 208V rated motor should not be run on 240V, nor should a 230V rated motor be run on 208V, motors rated 115/200-230V or 115/208-230V are fine either way, older 3Ø motors rated 220/440V will be fine on either a 208 or 240volt supply when connected for lower voltage. A 208V rated motor should not be run on 240V, nor should a 230V rated motor be run on 208V, motors rated 115/200-230V or 115/208-230V are fine either way, older 3Ø motors rated 220/440V will be fine on either a 208 or 240volt supply when connected for lower voltage. Please help. The motor has rocked up with 230 V winding but 3phase connections. 230V (the actual nominal supply voltage is 240V) is probably too high for How about reordering a single phase version? These motors are not usually at risk. Since a standard three phase motor can be 200 or 230V, most know that 230V is no good for 208V nominal systems, and Tom quoted 110.4 which doesn't permit a 200V on a 208V system, what's a person to do? I have ordered a electric motor from Germany with 240 V assuming it will be single phase. A 5 hp motor on a 110v would be pulling over 30 amps. A local motor supply shop had some interesting information on this. 230V 3 Phase Motor on 240V Single Phase Supply Answered. 6 and up wires is reversible and may be able to convert from a 3 phase line to a 2 phase line depending on where you live. I would be using a VFD with the usual 240 or 250 output, whatever it is. Typically it ranges from 110 to 125. It was running on 255 (approx) volts and the vibration damaged the motor. Your 110v circuit that you would plug the motor into would always trip, because 110v circuits are 20 amp or 15 amp breakers only. I assume it will not be a problem, but I thought I would come here and see if anyone can confirm it. I don't have a use for the motor … At 60Hz, the motor will run at 20% higher speed than it would at 50Hz, so it may require a further 20% increase in voltage. SOME 230V motors might run weakly when only half-voltage is supplied; more likely the motor hums, doesn't run, and might be damaged. Otherwise, the motor speed will still be reasonably close to the original synchronous speed, the blower will still absorb nearly the same amount of mechanical power, and the motor will draw excess current and overheat. There is no rigid spec that it's stuck at, and basically anything that's rated for 220 or 230 or 240 is going to work fine within the range. The power input for the motor is however 1/4 of the rating. The latest industry news—straight to your inbox. Hi, I am a ME with very limited knowledge on electrical side of the world. 3-phase AC motor uses 3 phase power supply (3 ph 220v, 380v, 400v, 415v, 480v etc. A 208V rated motor should not be run on 240V, nor should a 230V rated motor be run on 208V, motors rated 115/200-230V or 115/208-230V are fine either way, older 3Ø motors rated 220/440V will be fine on either a 208 or 240volt supply when connected for lower voltage. A friend wound a single phase machine that can best be defined as a phase adder. I want to use it on Aus Mains power, and am wondering what modifications i must undertake. Picked up an HVAC blower/motor from someone on CL with the intention of building a downdraft table. An quick internet search reveals several sources that all say no, but I am concerned that the people answering the question don't know what they are talking about - as is often the case on the internet. Just to see what all those connections mean. The motor has rocked up with 230 V winding but 3phase connections. The current draw from this motor at 120v is ~2.3A and at 240v it is ~ 4.5A. During inrush, the voltage may drop to 230V, or even 220V, but these are within the specifications of the motor. Normally the military uses MG (motor=generator) sets. If you attempt to run a 240v drill on 110v then the motor will draw far too much current and damage almost all the switches and control systems. So, of course, when I finally get around to testing it, it's a 208-240V motor (sigh). Will a 240v motor run on 220v? By closing this banner, scrolling this page, clicking a link or continuing to browse otherwise, you agree to the use of cookies. I had planned to hook it up on a double pole switch feeding a three pole to rig it for either 240 or 120, but after hearing it run furiously at 240v, I decided to dial it back to just 120v. If you want to know more or withdraw your consent to all or some of the cookies, please refer to the cookie policy. I have a motor thats rated for 220V single phase.

You'll often hear voltages in your home referred to as 110V, 115V, or 120V. The phase adder has extra internal winding's which add the two more time displaced phases that let you power your 3-phase motor at the exact frequency. The motor nameplate voltage would be shown as the "utilization voltage" and will say 230V, or better yet, "208-230V". Mains Plug (US) --> Two Speed Switch--> Motor. I think with expected voltage drop, you could use judgement, since of course we do place 200V motors on 208V systems. One reason small motors sometimes run without trouble at 230V on 460V supplied drives is that, even tho they are wired for 230V, they are would dual voltage 460/230. Hi, I am a ME with very limited knowledge on electrical side of the world. Im trying to run this motor but it doesn't budge and I don't even hear a hum. No, you can't do this. While most of the world uses 220-volt electricity, the United States uses a combination of 220v and 110v appliances. Question: Should I replace my 230v pump with a 120v pump? I need to know if a 240 volt ac squirrel cage fan motor can be safely run on 120 volts ac. ), especially in household appliances. It came with a squirrel cage fan and housing. So, if it was a 240V/50Hz motor, then the 120V supply needs to be at 25Hz (which is probably not practical). 10 volts is nothing service can vary by 20 volts. The motor is rated for 230/460, and the AC in my garage measures 250. The 220v wiring is used for some refrigerators, washers and dryers. The forums are retiring in 2021 and are now closed for new topics and comments. Is there any chance I can connect this motor to our single phase supply??? Voltage Differences: 110V, 115V, 120V, 220V, 230V, 240V . Sign up for our eNewsletter now to stay in-the-know. Normally it's between 220 and 250 vac. This can be confusing but the bottom line is they are referring to the exact same thing. Do note, that because of the inaccessible internal connection you cannot use a Delta motor winding. A 240v engine will offer more torque of 220v. Reply: Donny, ), but in some actual applications, we have single phase power supplies only (1 ph 110v, 220v, 230v, 240v etc. This website or its third-party tools use cookies, which are necessary to its functioning and required to achieve the purposes illustrated in the cookie policy. 2016/07/12 donny47% said: 230v spa pump vs. 120v. At the time they stated it ran on 120V but I was in a hurry so didn't check. My house has 240V single phase. Still not low enough for what you are asking though. 120V is the AC voltage on a single hot … Motors that are wound for a single supply … 0 0. I belive i cannot run it as is as the motor is designed for 110v (written on the side). GENERALLY, responsible motor manufactures do not list the motor voltage as "240V", that is what is referred to as the "distribution voltage". The wiring between the switch and the motor is via four 1N4007 diodes (to rectify the alternating current). Even if you don't blow fuses and burn out switches you would damage the motor windings. Three phase asynchronous AC motor is widely used in industrial and agricultural production due to its simple structure, low cost, easy maintenance and easy operation. Your motor is rated at 200V at its terminals to allow for some drop between your service entrance, through feeders, branch circuits, etc. Give the motor a full 240V before it starts. (P= 1.73*(V^2)/R) (240/480)^4 (the actual output will be less and 1/4 due to the mechanical losses of the motor being a greater fraction of the output total). We'll bring you the most relevant peer-to-peer conversations happening in the trade and tips and tricks to help you get the job done. The wires in the 110v circuit won't be able to handle the heat. The 220v has only 2 cables, the 240v has 3 cables, ignore the terrain. There … Some 3 phase motors have 2 wire and 3 wire connection diagrams ether on the maker plate or under the connection box plate. Any device which will help to use this motor. The refrigerator will not begins to 'run' or will just hum away.....SIMILARLY, your 230V will be mightily under power when a 115V is provided ... many single phase, 230V motor has a bell-end , where the internal coil-ends are joined to make the motor either a 115V or a 230V,,,see if yours is re-wire-able....review the nameplate. They tested a Baldor 3 phase, 208 volt motor at 208 and 240 volts, under no load. Double all that for 240, which is nominally 234, but can be as high as 260 or as low as 210. Keep in mind however, that the output voltage is never higher than the input voltage, so if you only give it 240V, it will only run a 240V motor, not a 480V motor. Convert 220v, 230v, 240v 50Hz to 110v, 120v 60Hz When you buy an 110v (120v) 60Hz appliance from USA, and run it on 220v (230v, 240v) 50Hz country (i.e. Then you will have another problem. It can't create voltage from thin air. Should I replace my 230v pump with a 120v pump? The lower 110v wiring is used for most standard appliances and devices, such as computers, TVs and table lamps. Another concern is the motor appears to be for a 50Hz three phase power supply, but the power supply on site could be at 60Hz 208v, so we must take that into consideration, too. I need to convert 120v to 240v to run a pump. I have ordered a electric motor from Germany with 240 V assuming it will be single phase. If you design it to have 230V before it starts, it may drop to 215 or 205V, below the motor rating. The Reverse will quickly burn up a motor (set for 240v run on … So the engine has to be designed to match the power source in which it has to be hung, so the sockets 110, 220 and 240 are configured differently to avoid connection to the wrong power. 208 volts = 2.9 amps 240 volts = 3.6 amps On their shelf, they had another 208 volt motor that was brought back for warranty.
