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.

all,
just getting back to my search for a new controller for our mars 48v brushless - powering a 5,600 lbs 27' sloop. (we never hit the water last year)

we have an older controller that requires a delay between forward and reverse, making docking or mooring in our strong currents more adventuresome than the actual sailing. many recent posts seem to touch on this topic, as well as the equally fun one of drive belts riding off of edgeless pulleys) however, my electrical ignorance prevents me from gleaning the info i really need to make a decision. is there a consensus out there as to what might be the best (SIMPLE)option for us?
thanks!
