I picked up and old wheel chair and got the motor controller out of it. I wanted to try and use it for a soft start controller for an auto starter motor. I have a gyrocopter that uses a 24 foot , free spinning rotor blades. I presently use a starter motor to start it spinning, but you have to momentary press a button and that hits the starter with the full current. I was thinking that maybe with this controller I could soft start the rotor blades a little at a time until up to speed.
I have seen controllers advertized that you can use a 5k pot for speed control of a motor. But they are rather expensive to purchase just for me to experiment with. I came across this old controller and wanted to experiment with it.
Would anyone know where I can get a schematic for controllers or info on them? It is an Invacare mod. 1109528
Thanks

Invacare has this to say about their products:
"Invacare does not disclose drawing schematics to the public."
You may see the full FAQ that I found here.
Maybe you could post a photo of the controller. That might give someone
an insight into how it works.
Good luck.

Hey, what do I know?
Re: DC motor controller
Greetings Roger,
There was a similar thread on another forum, here.
operate an auto starter motor, which could draw
several hundred amps under load.
Why not find two six volt batteries and start with
one to get the motor moving, then swap to both
for full power?
Comments Welcome!

Hi guys,
thanks for the replies, I figured the company wouldnt offer any help.
I can reverse engineer the thing. It would just be eaiser with a schematic.
When I was younger reverse engineering was fun but now I am older and I guess less patient. But this one may be interesting.
That was my post in the general forum too. I just thought maybe you robut guys would know more about it since you deal a lot with PM moters for you bots.
I think the controller will handle a PM starter, which is what most starters are these days. The motor wont be drawing as much current starting a rotor on a gyrocopter as it would on a high compression engine. I will just have to hook it up and see.
Thanks
Roger

ya know, some electric bike motor controllers have a soft start feature,
i have a china made one on my bike, that i salvaged off of a electric scooter its a 24 volt controller rated at 40 amps. it is right now connected to a 36 volt 550 watt electric motor to drive my bike. wish i had the room to attach another battery to get 36 volts to it. but i am space limited to just 24 volts.
not sure how many volts/amps your motor is. but good luck..
seen some guys have a cable driven starter that runs off of a wheel that rubs on a flat pully off of the engine shaft.

jaycare has a kit that might do what you want .its a 12-24 volt dc motor control.
