| Novak Motor Problems???
I am going to call in the a.m. but I wanted to see if anybody else has had this problem. Hopefully its an easy fix. There are 3 different cars. All have the MMP, 3s. One Axial, 2 Losi comp crawlers. The problem that we are having is that the MMP completely shuts down (electricity gone) at random. Steering/dig still stay on since it uses the BEC. Red wire is clipped on the MMP. At first we would just pull the deans on the lipo and turn it back on and it would work. As time goes on this may or may not work for us. We finally found out that the MMP will turn back on if we pull the sensor wire or if we turn the drivetrain by hand causing the rotor to move positions. We have tried all the different motors in all the different cars with the same result. We have one 18.5 that does NOT have this problem and will run all day in all the cars. This is why we think its a Novak issue. Motor, ESC, Battery all get Very warm when just plugged in. In fact, I am pretty sure it ruined 4 of lipos before I figured this out. Tried updating software and firmware on the MMP, even tried older versions with no luck. Tried multiple sensor wires. Motors that are having the problem: 21.5t Ballistic with 14mm rotor 21.5t Ballistic with 14mm rotor 13.5t SS pro with 12.3mm rotor (brand new) 18.5t Ballistic with 12.3mm rotor 21.5t Ballistic with 12.3mm rotor Most of these motors are under a month old.

Are you using the same sensor wire?

Try putting the MMpro into sensorless mode and see if the heating occurs just sitting there. Are you swapping the same ESC around for all the rigs?

Not the same ESC. Different ones in each car. Last edited by Erik D_lux; 09-17-2010 at 11:09 AM. | |

Do you have any other motors to try? That is strange that all four setups exhibit the same behavior. Maybe call Castle and see what they say?

BTW, two of the Novaks serial numbers are one off from each other so we think it may have been a bad batch. The others may have been made at the same time too but their serial numbers change with the different turns. Its also too weird that my one 18.5t Ballistic runs like a champ in all cars. | |
