Is the noisy motor genuine Currie or Chinese Currie "STYLE" motor? Lindsay

For many years, Currie motors have been made by Unite.

I believe it is the Unite (Model? Design?) motor, built by various manufacturers (Shanghai Masston Co., Ltd. +others) for Currie.

2006 era cooling mods!
Ignore 1st picture!
Post & other pictures are for the MY1018 geared motor.

Seems newer Currie motors are made by XYD.

Can't say who Currie uses for building their motor these days. But I have 5 Curries motors (all 450w 24v) that ether came on an '09 EZip or were sent to me as replacement motors from Currie. Only 2 of them are from the same manufacture. So I think it's far to assume that Currie has a basic spec and price shops and buys who ever can deliver at the cheapest price. BTW, while the mounting holes are all the same I found that you can not interchange the covers on the differant brands. owever, I believe the bearings are the same but can't say if the gears are or not. Each motor has a vering degree of noise. I had one the was almost wisper quite until I removed the cover screws to mount it. Then true to these motors it sounded off.

What makes the newer currie motor less powerful? It's the same size I believe. I just picked up a cheap ezip ecoride on craigslist, for the quiet currie motor on it. I plan to either add it on my main 9c ebike, or do a lightweight build with it as a mid drive to the front chainrings like my old ebike builds.

I just rode the ecoride with it's single speed gearing. Of course on 24v it has no balls whatsoever, but I think I could overpower it and not kill it if I am smart.

As a crank drive, in combination with a separate 9c drive system, I could achieve very good efficiency by not using the 9c below 15mph and just the currie on those starts, which would do fine.

veloman, Just wondering..are you sure you have a 450w motor and 35a controller? Currie sells 250w models woth a 20a or 25a controller as well for Canada that have found their way into the US. The motor and controller look exactly the same too. I don't think the motors are marked but the controllers are marked so you should be able to check it.

What voltage are you planning to run this motor on?

Does anyone know where to get an adaptor to mount a 13T single speed freewheel onto the motor instead of the fixed 9t sprocket ?

hi miles i measured the inside of my gear and its around 11mm id. the links you sent is for 1/2 inch or 5/8 id? unless i am measuring it wrong

[Miles]

Yes, you'll need a bush to make up the difference. Is it a plain shaft?

[jk1]

yes it has a 4mm wide keyway . i want a proper version of what this guy did diy :p http://www.youtube.com/watch?v=eY41JBi3 ... ata_player

You can make a bush and then cut it away to clear the key. There is a slightly larger keyway in the Staton adapter than on your shaft, so you'll need to make a new key. You could use the FFR adapter and forget the keyway. Or, you could commission someone to make a custom adapter.....

The new tricruiser 36v motor is quiet or not so loud.
