Will MP4 work with external BLDC Controller (let's say the same one as MP III would be)?
Assuming it's just the controller that is different it may not make any difference if you wish to use an external controller.
Although, if the new sine wave controller is sensorless then it would not require hall sensors, but we won't know whether it still uses hall sensors until we can find a bit more information on it.
Even if it doesn't have hall sensors, you could still use a sensorless external controller as the stator windings are unlikely to be any different to the MPIII.
This motor is recommended to be run with a 24, 36 or 48 volt battery.
Dennis, what Gary was try to get across is the fact that it should not be used with a battery with a nominal voltage of more than 48V. Because the controller is described as being able to accept voltages of up to 60 volts maximum, some people will wrongly assume that it is OK to run it from a 60V battery, but as we know, this wouldn't work.
There are probably thousands of MPIIIs running on 48V packs without problem. The early MPIII controllers did have some teething problems, but the later replacement controllers still seem to work fine, so there should be no concerns about running on 48V packs.
I have run all of my GM motors on my 51.2V LiPo pack without any problem
(apart from the dual controller attempt where one controller died instantly and the other surviving controller that was further modified eventually blew many months later while delivering over 97Amps)Do you remember anyone complaining about a fried MP III controller running at 36V? 24V?
Many of the failed MPIII and Smart Pie controllers I've seen on the forum have been caused by water ingress.
