I picked up a Sevcon Millipak controller and a Mars PMAC motor to go along with it. I only need my go kart to move forward. Can anyone help me out with a layman's wiring diagram?

Re: Sevcon Millipak and MARS PMAC wiring help

The way I understand Sevcon Millipak it is only meant for brushed "DC" motors or separately excited motors. Your MARS however APPEARS to be a permanent magnet alternating current (thus PMAC) motor, or better described as a permanent magnet synchronous motor. That motor requires a Sevcon Gen4 controller for example, with three output phases that must be connected to the three bolt and nut terminals marked U, V and W on the motor housing, three hall sensor inputs U1...U3 that come from pins 1 to 3 in the 5-pin connector of the motor, a Hall sensor power output that goes into pin 5 of the 5-pin motor connector, and a ground connection that should be connected to pin 4 of that 5-pin connector.
However, as I have no reference of what motor and Millipak controller you are actually using this is only educated guessing. Any links to proper documentation of the products you bought?


My rides:
QvR vR one: a Swiss package of pure understatement - innocent and to some eyes (from some angles) exceedingly ugly looks, but with raw and hardly containable electron power up to real 95 to 100km/h! And a literally rock-hard suspension due to a carrying capacity of twice it's unladen weight... Now converted to more controllable and efficient brushless motor and vector-contoller.
