Heinzmann Motor and controller kit $75

Post by DanGT86 » Feb 09 2020 10:45am

$75+Shipping OBO
Parts are in St. Louis Missouri
Helping my friend sell some ebike parts he was given. This is a Heinzmann 500watt brushed DC motor kit. It came from one of those recumbent trikes with the really long front end. The motor says 36v so thats what I tested it on. It runs about 150rpm at that voltage like the tag says. Before scrapping the trike we rode it around and it all worked fine under load. It's a bit dated technology in the ebike world but appears to be a nice kit with high quality connectors. Hub is no longer laced to a wheel. Controller and all connectors are wired to a plastic ammo box that used to have the old SLAs in it.

Thanks for the link.

This motor looks like a lot higher build quality than the stuff we all mess with now days. I was considering drilling and tapping the side cover for a sprocket mount and using it for a cargo trike. Definitely not a hot rod motor but it looks way overbuilt in the quality dept.

2old

Got your PM and figured I'd respond here since you just made me realize there might be some fitment issues with this motor on standard mtb forks. It looks like the proper spacing for a front mountainbike fork but it rubs on my suspension forks. The stamped steel torque arm integrated into the motor also appears to interfere with the disk brake mount. It looks like it may be possible to mount it with 3-5mm worth of washers but I don't see how a disk brake caliper will clear.

I guess this motor is destined for weird non standard projects. I wish it had a disk mount to hang a sprocket on. It would be much more versatile that way.

Dan, I a$$ume it is compatible with front rim brake forks or forks without a brake mount that are spread the 3-5 mm; is that correct?

I honestly don't know. I have some throw away forks I don't mind possibly bending I'll try to spread them with some washers and see if I can get some pictures. Probably wont be until the weekend though. Sorry.

If 2old there falls through, I might be interested in this too. I've got some Sondors parts including a base 350w hub motor, and it might be perfect for a junkyard AWD build.

CS, you can have first shot. I thought it would be fun to play around with a brushed motor since I haven't seen one for a looooong time.

Alright guys. Good news. I put 3mm of spacers per side on a non suspension fork and it looks like it will fit and spin just fine. It also clears the IS brake flange and the torque arm lines right up so it would be super easy to make torque arm that uses the brake mount. Actually the torque arm will line up with the flange such that you could just drill a hole in the torque arm and uses a simple bolt and washers. No extra part required. The wheel will require a bit of dish but that shouldn't be a problem since you'd be lacing a wheel from scratch anyway. So the main question is really does this motor deserve the effort of a wheel build?

"Deserve" a wheel? Hell, this thing's the Flathead inline 6 of the EBike world, it probably does!

Okay, i'll poke around at my Sondor's parts- it should also be a 36v motor, but it makes sense to make sure. I should have a response by tonight. Dan, should I PM you shipping info? I wouldn't need the SLA battery; just the electronics.

Before I forget; i'm thinking a full trash-n-thrash build here. 350w Brushless Sondor motor up front, this brushed motor out back, wire both to the same throttle, hardy battery pack from luna cycle and reuse as many free parts as possible. Good idea? Bad? It'd be my first build and I think i'd be better to be cheap as hell so I ain't mad if I break it.

It is a charming piece of history.

It is not wide enough for a rear 135mm mount. It is made for front mount. It also has no freewheel or disk flange so I don't know how you would use it in a rear unless it had no pedals. Might make a better mid drive with as sprocket screwed to the outside shell.

I do not know if the throttle is 5v. All the cheap BLDC controllers I've messed with have worked basically the same but I have no idea whats in this brushed controller. I can try and find out if the throttle is zero to 5v if you think you want to try it.

The SLAs are long gone. If you want the setup should I remove everything from the plastic box or do you want that?

Yeah, remove it from the box, I won't need it. If you could figure out that throttle I'd appreciate it; keep me from going in blind.

No freewheel? I thought it was a hub motor- SpinningMagnet's link shows it was.

Probably the same guts but its a front motor for sure.

Throttle signal from the controller is 5v. The throttle measures 5k ohms closed and a few hundred ohms wide open.
