[Electric Boats] Re: controllor for mars brushless 48v

 

The SEVCON PMAC solves this problem - order from Thunderstruck-ev and tell them it's for a sailboat - they will put the right "personality" into the flash.

I believe the MARS controller (the current one) also solves this problem - but cannot personally verify. Buying that would give you the benefit of being able to use your existing harness and keep your old controller as an emergency spare.

So, what is the older controller that you have? If it is the mars boat controller (ME0504C), you can rig it to avoid the need to have a pause between fwd and reverse. Assuming that's the one, you need to ensure that the on/off switch is not mechanically tied to the throttle or fwd/rev. I have the BLDC mars and the matching controller and I can throw it from fwd to reverse without a pause.

Re: [Electric Boats] controllor for mars brushless 48v

 

Denny,
 
I experience a lag when going from forward to reverse in my electric powerboat running my 5KW Golden brushless DC motor and Controller.  Can you explain to me why?  You seem to know about this as you mentioned about the Sevcon Controller.

Sevcon PMAC will go from F to R instantly.  Be sure to get the firmware version that has been updated to do this.

Join the OMC group. They would love your question over there. They are an open source group building their own motor controllers, and offer hardware for the technically challanged.
