Speed controller for BLDC washing machine motor

This video shows how to control an LG 3 phase BLDC direct drive motor with a variable frequency drive inverter. The inverter I used has a 120 volt input and a 220 volt output with a maximum frequency output of 599 HZ. The maximum output of the inverter is 0.4 KW which will drive the motor at 1192 RPM @ 475 HZ . I don't recommend that anyone try this at home and if you do it is at your own risk. High voltage can kill . Read all the safety instructions in the VFD inverter manual. The inverter shown in the video is a TECO- Westinghouse model L510-1P5-H1-U .

Tried several different BLDC controllers for these washer motors and this is the only one that practically works.

i love the sound of the direct drive system in LG machines

Great to see a lot of people trying to run these bldc motors. Just to let you no a vfd will work but to acquire more rpm they need 310vdc and the frequency is over 400khz. I have achieved that to prove it and I got one to spin at 4k rpm now that's scary. I am working on another one to go faster.

I always wanted to see someone control this motor while it was inside the washing machine, that would be super cool!

Thanks gotgas63. This is exactly what i wanted to know. I'm looking at controling a Evap BLDC motor.

@gotgas63 hey u have to try running with this VFD a 6 or 7 inch drum instead. cuz the bigger the drum the bigger the volume it needs.
Volume = Voltz and also frequency.
That VFD will work on smaller width drums. but for that 12 inch u need a much more beefy powerful VFD.

Would LOVE to see a follow-up to this great video, especially the "other control" method mentioned. How does the added wire modify the circuit to create such a watts savings?

[RachidHidada-rcwz]

So, this electric motor can be run on VFD. Sir, I have some questions, please. Does the motor operate efficiently without connecting the hall sensors? The other question is: Is it possible to reach high speeds (6000 rpm) and how much electricity does it consume, the electrical power of the electic motor? Sorry, Sir, for my many questions, and I hope for a response from Please and thanks in advance.

Hi. I'd email you directly, but you didn't provide an email address in your "About". I have a question, assuming you know how these DC flat motors mount In the LG Front Load Washing Machine, do you think it would be possible to connect the VFD (such as the one you depict in your video) While the Machine is Still Hooked UP to the wiring harness as it came from the factory? There doesn't appear to be enough Space to do this. Do you think it would be possible somehow with a dual female wiring harness, thus allowing for the washing machine's male plug to plug into the female receptacle, as well as a manual control VFD control, too? The Reason I would like to do this, is because these front load washing machines--although the latest models have gotten perhaps a Little Better (I have a newer LG Front load, that was purchased in later 2021) with the pre-balancing the spin load before the onboard microprocessor of the machine allows the motor to start ramping up to spin speed--they microprocessor programming is Still Too Super Sensitive / Not programmed quite right. I can do a Better Job of getting the load balanced enough and gradually ramp the motor up to spin-extracts speeds! What do you think? Thanks.

Great! Wich is the correct version for Europe 220V input and output if possible around 400V? Thanks again, hope you put more new video in this channel.

bro. is possible to run .38HP bldc motor the drive is damage and i want to eliminate hall sensor with that kind of vfd

[BougainStranot]

I tried to control one with a Siemens Sinamics V20 VFD and it did rotate at 20 RMPs but got hot really quickly.

I did not have the original shaft from the washing machine. I made a shaft out of a thick 3/4 inch washer and welded a 3/4 inch shaft to it. The motor is mounted to a 1 inch thick piece of plastic sheet. Two 3/4 inch pillow blocks are mounted on each side of the plastic sheet. I used 3 x5 paper cards on each magnet and dropped the stator in . You my need to use multiple 3x5 cards on each magnet, depending on the motor you have. Then insert the shaft into the pillow blocks to determine the location for the stator hold down bolts . Spacers are required to keep the stator at the proper height.

Hi bro
I want to ask that can we increase its speed up to 5 or 6000 rpm

Hello. I have an idea to run the inverter air conditioner compressor with the help of a vfd, similar to the one in your video. Inverter air conditioner compressors are called dc inverter or simply inverter. In addition to the U-W-V cables in the compressor in my air conditioner, there is a fourth cable named N. As seen in the video, this 4th cable is connected to the intersection of the phases in the middle. As far as I have learned, the air conditioner works in open cycle until it reaches a certain engine speed during the first operation, then it continues to operate by switching to closed cycle. The difference between open and closed loop is to ensure that it does not fail by sending the correct energy to the correct phase of the running motor under load.

My question to you is this. Can I start this engine with the help of a vfd? Also do I need to look for the SLV feature you mentioned in the video?

Thanks.

[sachinsherry]

is the motor automatically speeding up when you try to stop it or is it the controller doing that

[iseeyou]

Hi there, are you able to take the rpm up to 1500rpm with that controller?

[AlinNZ]

Hi can you tell me if this is the same motor model you are using lg wdc266c03r ?

[vineshteeluckdhari]

Hi I want to use this Motor to drive a LOW 300RPM Wind Turbine Motor to generate electricity, do you think its a good idea.What issue would I come up against this setup.Thanks

[fredhebert]

You said in the video you don't recommend it for generator can you explain that in details I appreciate it thank you
