content: I have a washing machine (universal motor), and I wand to control and maintain it's speed regardless of the load.I bought a ux-52/003, 400W version, that I thought would do the job, but I'm not sure anymore.It is supposed to control motor speed, direction, and many other functions as soft start, etc...The motor has 6 wire, two for the tacho, two for the static windings, two for the brushes (through the rotor winding).I cannot find the proper way to motor to the controller....By the schemes, I can't figure out how it is supposed to be wired. Haven't found much more info on the web neither.I tried some arrangements, some with better behavior than others, but the motor is always making lots of noise, and I'm afraid I'm going to damage something.There are also some parameters in the configuration I'm not sure of like the motor magnification.The xu-52 has two entry for the tacho, and 3 entry left (labeled U1 U2 and Z2) for the 4 motor cables.Anyone knows if this controller is working with universal motors, and how it is supposed to be wired ?I've attached some images of the UX-52 2 boards (second one is with the controls) if that's any help. Here is some scarce documentation about ithttps://www.nvcnc.net/ux-52-multifunctional-motor-speed-controller.htmlThanks for any help !

content: The wiring diagram shows a single phase induction motor, and the buy links confirm its for induction motors. It is very unlikely to be compatible with a brushed (universal) motor as they use a completely different method of speed control.

content: I agree. The washing machine motors I know all have tacho feedback due to a completely different operating mode.Also, 400 W is a joke.Normal size is 1...1.5 kW for domestic washing machines, upwards there's no limit.

content: Thanks a lot for the help !@BentaThe motor is actually 250W. Maybe the 1.5 kW are because of the heating element ? The module has input for the tacho feedback.@lan.MOk, I was afraid of that, the diagram was bugging me. I completely missed it as It was not written on the page from which I bought it.After gathering a bit more information, some sellers are specifying that the controller can only be used with certain induction motor compatible with speed control (for eg 31K15RGN shown on the image).I can't understand technically the difference between induction motors allowing or not speed control. I happen to have an induction motor lying around, how to know if I can control it's speed... ?I'm just trying to figure out a way not to loose my money on this ux 52 !

content: Hello, I was working today with similar piece, and everything are in Chinese. and was trying to install as inverter for a Lathe. So i can give you what i learn bellow. I does not work good for now, but i trying my best to understand the issue, now i cannot change the speed rotation of motor idk why. im in process of adjusting settings, maybe it's fault of bad base frequency or major level of it in inverter settings. The motor name is Ersatzmotor Industriemotor 230V 50Hz 370W 0,370kW, there is no any info about that, and i recognize, that he have five wires, L,N,GND,CONDENSER1,CONDENSER2, so everything should be ok.Quote
