ElectroCrafy model BDC3330

[Dally]

Hello all, just registered. Google gave me your sight when typing BDL3330. Anyway I am in a fix. I have bought a couple of ElectroCraft BDL 3330. But could anyone shed some light on its wiring. As it has 3 power wires heave gauge and about 5 other small wires. What do they all do?? Please help.
I am building a skid steer chair and am using these motors. Big fat tires etc. Regards Dally

Never heard of them. Do you have a picture? Sounds like brushless motors.

Those sound like the motors from a Quickie P222 (not SE). If I am right, they are decent motors with an interesting gearbox (single stage bevel reduction), but they are not brushed. I have called them brushless, but I have also heard them called asynchronous three phase motors. I have not taken one apart yet. There exists a 65 amp P&G Pilot+ module that is compatible with them, but I have no idea what the cost from P&G would be. You also may still be able to get it as a replacement part from Sunrise, but probably at a very high price. It may only be rated at 65 amps, but a chair with this controller can be fairly lively.

For somebody who really knows motors and really knows their way around electrons, there is a Roboteq brushless controller that I have a hunch might work for driving that motor. I have a P222 in storage that I would like to use to test this idea some day.

3 power wires and some hall sensors for speed control

Thanks for those- I feel more certain now that it would be compatible with the Roboteq brushless model.

Thank you so much all of you for responding to my post so quickly. And I think of all the dead ends I ran into from correspondence to ElectroCraft. Sounds like the controller from the Quickie P222 would work, but no one liked the P222 from forums on it. A friend of mine had one and he hated it. I have an old Quickie P210, same as the P200 but with a reclining back. Looks like a real dog, but is best around the shed. I also have a Invacare with 14" rear and 10" front tyres. It is OK around the property but hopeless in tight areas. They all get bogged when Autumn and Winter arrive.
This is why I am building a 4x4 skid steer with larger tires than on the rebuilt F55 on this sight. How many ways to skin a cat eh'. The next 4x4 will again be different than the present one. You just think of better ways to do it better or easier.
Thanks for the info guys. The Roboteq controller sounds like the solution as yet.
