Using three phase AC synchronous Ford traction motor and SKAI with the following specifications :

This page (http://www.commoditiesrecoverycorp.com/electricmotors.htm) says they are 6 pole.

Might have the following temp sensor (to be confirmed): KTY 84 - 13

Ed's estimates (16MHz temperature data on digital line PC8):

  • 440Hz = 30 deg C
  • 250Hz = 220 deg C
  • 200Hz = 290 deg C
  • TODO - calibrate and test!

Good explanation of contactors and precharge circuit: http://liionbms.com/php/precharge.php

A poor discussion on the subject: http://www.diyelectriccar.com/forums/showthread.php/gigavac-contactor-faultyi-23236.html Off the top of my head, it is suggested that these rules be broken at various points in the discussion

  • Do use the correct suppression system for your contactor -- make sure it turns on and off fast enough, make sure not to blow up the circuit driving the contactor
  • Do use a precharge resistor capable of continuous operation
  • Don't apply power to the controller all the time through the precharge resistor
  • Do use an appropriately rated precharge contactor
  • Do monitor the system to ensure the contactor is working.

Some useful contactors and fuse links:
