Looking for some advice on wiring curtis 1209B to Etek brushless.

I have a briggs and stratton..ish etek 15hp and a curtis controller. Are these compatible? Can I find a diagram for the connector plug for the motor?

Thanks,
Andrew

No, they can't be made to used together, since that controller is for sepex motors.

And what do you mean by a B&S-"ish" Etek? The Mars brushless?

There's the manual for the controller, though. Also, what's the second half of your controller's model number?

1209 controllers are SERIES WOUND motor controllers. THEY ARE NOT SEPEX controllers.

But Link is right, its NOT a brushless DC controller.

We really need the full model number of motor and controller to confirm 100%.

From the sounds of it, you need a sevcon BLDC controller.

Wait what? That's weird. I think you're right, but I took a quick glance at the wiring digram and saw that there was a separate power connector for the motor field. Why's that there? :/

its because they're using a reversing contactor (since the controller cannot reverse polarity).

With series wound motors, you can't just switch polarity, you have to switch the flow of current in the field windings. Look at the schematic again. If the contactor is in Forward, the flow goes from M- on controller to S1 through to S2 then to A2 and through to A1 back to M+. The A2 connection is for Plug braking.

It is a series controller though, S1 and S2 are series wound notations. F1 and F2 are sepex wound notations.

page 12, its the plug braking diode.

Oh yeah. It was that fourth power tab that threw me off. I only usually see three on series controllers.

yeah, threw me off at first too. I've got a few 1205's laying around (broken) and they're the same way.

Ok, I bought a Sevcon Millipak controller...the wrong one! I need a 20 pin brushless and I managed to get a 16 pin controller for brushed motors. Is there any way to use this with my brushless Etek? If not, does anyone know where I can find a reasonably priced Millipak brushless controller.

Any help is appreciated.
