    Which Electric Vehicle would make the best 3 phase grid power emulator?

    Excellent point, Chalo! The sawmill in question runs off a large smelly ICE diesel in other versions of mine.. so it is designed to lug around a heavy motor on the saw head. This video shows the diesel motor about 3 minutes in if you don't know what this kind of sawmill looks like. As you can...

    Which Electric Vehicle would make the best 3 phase grid power emulator?

    Thank you again, Jack! Interesting point about the Tesla S. So that would likely be the best choice to drive a non Tesla induction? Do you have any idea what commands the computer sends to the inverter to have it drive an induction motor? I was hoping to use a Nissan Leaf as they seem to be...

    Which Electric Vehicle would make the best 3 phase grid power emulator?

    Thanks for bearing with me. I really don't know what I don't know at this point and appreciate your patience! The motor I am dealing with is almost certainly a standard industrial 3phase induction motor. There is no electronic motor controller or Hall sensors or any of the fancy BLDC motor...

    Which Electric Vehicle would make the best 3 phase grid power emulator?

    One of the advantages of electric motors is their almost instant and steady torque curve in most circumstances. In this particular application the load or "steep hill" is modifiable by the user. If the load gets too big, the user simply slows down and or uses a sharper blade. With a sharp blade...

    Which Electric Vehicle would make the best 3 phase grid power emulator?

    This is exactly what I am looking for. As the load on the electric motor increases, the inverter compensates by throwing it more current to keep it moving at the same rate. Eventually I suppose it could bog down if I push too hard by trying to saw something ridiculously hard with a blunt blade...

    Which Electric Vehicle would make the best 3 phase grid power emulator?

    I am trying to keep this as simple as possible with as few modifications as possible. Not sure boosting is needed plus I have no idea how to do it ;-) If a 360VDC pack can give me 257VAC RMS, then that is about perfect. The motor would start to slow as the voltage depletes, but definitely not...

    Which Electric Vehicle would make the best 3 phase grid power emulator?

    Lol.. that was my original intention... to convert an existing mill and use the EV motor and entire drivetrain from battery to wheel hubs. However isn't a 3 phase industrial motor pretty much the same animal? The EV motor gets 3 phases of power also, right? Plus wouldn't the EV motor be a lot...

    Which Electric Vehicle would make the best 3 phase grid power emulator?

    Could you clarify with what it peaks at exactly? Why did you mention 208V versus 240 for example?

    Which Electric Vehicle would make the best 3 phase grid power emulator?

    Thanks for the response. Not entirely sure I understand that. Don't most EVs support "cruise control" which would give a constant rotational speed despite the load? Wouldn't the inverter not supply the motor more current on demand as the motor is loaded? I have tried to find a good write up of...

    Which Electric Vehicle would make the best 3 phase grid power emulator?

    BTW this is not a constant load. For a sawmill so it runs for about 60 seconds at a time with at least a minute or two break, so about 50% duty cycle tops.

    Which Electric Vehicle would make the best 3 phase grid power emulator?

    I am looking to take the battery, charger, inverter etc off a crashed electric car/truck and have it power a 240/480 VAC 3 phase motor. Nominal power consumption is 7.5kW. The voltage seems to be able to be anything from 208VAC to 480VAC, so pretty flexible. It runs currently off utility grid 3...

    Cheapo Voilamart E-bike kit... add reverse switch?

    Yup... none of those things are practical for sure! I will order the kit and mess around with the circuit board to see if I can get it to reverse. As I want six drive wheels on my build, it needs to be relatively simple.

    Cheapo Voilamart E-bike kit... add reverse switch?

    Great tip! I will order one and see if I can make it play nice. It seems like it should be something that is easy to add to a control board and I was hoping it was there but they didn't solder a wire to it to save cost (also typically reverse is not needed on a bike!)

    Cheapo Voilamart E-bike kit... add reverse switch?

    But there are other posts people have made modifying these boards to allow regen braking and such. Just wondered if anyone had seen a reverse on there. I want to put 6 drive wheels on this project, so need to do it inexpensively as possible... so prefer not to drop extra on new controllers.

    Cheapo Voilamart E-bike kit... add reverse switch?

    It is the standard kit that sells on Amazon or Ebay. There is no reverse wire pair specifically

    Cheapo Voilamart E-bike kit... add reverse switch?

    Hey all, I have googled around for this and can't find anything, but can the Voilamart 1000W or 1500W front wheel hub kit be modded to add a reverse switch? If anyone has made them reverse on demand, could you please share how?

    Thanks for the tip! Did you get the OEM Genze motor controller working, or did you replace it?

    Anyone done business with UUMotor?

    Hey.... so I also have been chatting to "Tony" at UUmotors. I was wondering how you went on after testing and what not. There are no trustable reviews of his stuff. He has posted a few vids on YouTube this year but again hard to say whether his stuff is decent or not. Anyone else have any...

    Radio Remote Control BLDC controller

    actually I guess I would need a controller with reverse capability! Perhaps the attached?

    Radio Remote Control BLDC controller

    I have tried looking for a thread for someone doing this but can't find one. If you can point me in the right direction, please help! :-) Looking to use two eBike /Scooter hub motors to drive a small 4wheel vehicle by remote control (radio operated). I am looking to use something like this...

    Low Cost Noob Programmable 1000W motor controller

    Can I assume there is not a dedicated watercraft controller also. Please help if you know of one

    Low Cost Noob Programmable 1000W motor controller

    It is definitely brushless. It has a cheapo 1000W brushless controller on there right now, plus it has Hall sensor wires. Do the KT motors have the ability to be put into reverse with the flick of a switch? I looked at them on Aliexpress and they don't seem to have a reverse option. Also...

    Low Cost Noob Programmable 1000W motor controller

    Hey all, I have spent hours and hours now on the forum looking at different controllers, and can only say I am more confused than ever. So many choices and prices going up into the thousands of dollars! I have a 1000W BLDC trolling motor for a canoe with a dead cheapo Chinese controller on it...
