e-bay motor Model MY1020???

Anyone know about the MY1020 motor? I see them all the time on e-bay, different people use the same part number but say they are different power ratings. right now i see them listed from different sellers as 350, 500, 750, 800 and even 1200 Watts. Which if any of these claims are correct? do they use the same part number but wind them different?

I believe they are made by Unite, there products are in a lot of the LEV's from China. I just remove a 24V 250 watt I had in the first E Scooter I owned. Several years ago the shipping would kill you when they started making the higher wattage motors, but that's no longer true. For the price they are probably decent.
Are you thinking about using one on the EV Warrior?

No, not on my ev-warrior, but i was thinking maybe on my scooter. I didn't understand why the same motor can be rated at 350 watts and 1200 watts. After looking at the site you said, i think i understand better. I " think" they are rating the motor all differently. If i am reading the specs right, it seems like the motor will run at 24v to 48v at 350 watts continuous to 1200 watts peak. I guess the sellers on e-bay can read them the way they want and spec it the way they want to.
thanks for the link.

I just recieved 2 (two) of the 750W Gear reduced MY1020's and 1 (one) of the 1200watt MY1020 motors from TNCSCOOTERS.COM

I hope to post a full review of them over the balance of the summer as they get put through thier paces with a variety of controllers in different applications.

#1 priority is the recumbent tadpole trike that I started earlier in the spring, as well as electrifying a Cub Cadet rolling chassis.

Unfortunately I'll be away from the farm over the next 2 weeks, but hope to start into those projects in early August.

Frank,
Since they both have the same motor number MY1020, i would be interested in what the difference is between them. If it would be the size of the wire, the number of turns, or the size of the magnets? If you take them apart to look inside or if you can see thru the case holes please let me know.
thanks

Hi everyone,

I've been waiting to write something on this forum, and about these motors; I'm surprised nobody else talks about them.

I once found an old Honda mini-moto kart. The controller and all the plastic had caught on fire, so we were left with the frame, 500W MY1016 motor (smaller version of the MY1020), and a half-dead 36v battery. We tied two wires close to the steering wheel, and touched them to engage the motor, straight from the battery. The kart would spin its single drive tire, and accelerate to around 15mph in about three seconds. Engaging the motor during a turn would instantly induce a spin (or, if you're skilled, a drift }:) )

After about 30min of heavy use, the battery would be dead, and the motor would be slightly warm to the touch. We ran it almost every day for a few months, after which the battery totally died. The chain started to bind from all the dirt, but the motor ran like a champ.

I can only imagine what the bigger motors would do. Unite Motor has a few bigger models on their site, but the biggest models we could find were the 1kW 36v and 1.2kW 48v. In addition, the same company that sells these on eBay has very cheap controllers. The only shaft option is an 11 tooth 25pt chain sprocket, so you'll have to be creative.

Happy motoring!

Hey Craig,
Good to hear from you, can you post some pictures of your motor and the brush plate?

I was experimenting as normal and rewound the MY1020 with 16 gauge wire. This is approx. 4 times the cross sectional area of the stock 20 gauge wire. I'm running my scooter with 6 12 A/H Hawker batteries.(36V 24A/H total) and the controller can source 300 amps. My first time out with the rewound motor was great, the power and speed was impressive for the first half hour. Then i noticed a reduction in speed and power, i was able to ride it home and then took the motor appart. Two of the 4 wires going to the brushes come off, yes it melted the solder, WOW. It got much hotter then i though, i resoldered the wires using high temp silver solder and ran 2 12 gauge wires into the motor. I'm hopping that the larger wires having less of a I/R drop will stay cooler and also help disipate a little more of the brush heat. I had a couple of small 24 volt blowers that run great at 36 volts and i mounted them to the end of the motor to keep the motor cooler.
I also rewound my Bosch 750 watt motor with 16 gauge wire. I haven't put it in my scooter yet, but the motor seems to run good after i balanced it.
