Shire Electrical Conversion

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

• Type 1PV5133 (some great pictures of this motor here: http://etischer.com/awdev/motor.html, and on http://en.wikipedia.org/wiki/File:SIEMENS_FORD-RANGER_EV_MOTOR_0.jpg wikipedia)
• F8Y8 148280 AC
• 4W S20 WII
• Th CI, F Rated battery voltage 250V
• Made by Siemens in Germany
• N515 0133 12
• KRX Antrib Asynchron
• RPM: 3500-9700
• Operating voltage 215 - 380Volt - 282 Amp (RMS 400 peak)
• 67Kw peak ( 30Kw continuous)
• SKAI3001G12

This page (http://www.commoditiesrecoverycorp.com/electricmotors.htm) says they are 6 pole? (is that right Ed?).

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:

• http://www.gigavac.com/products/contactors/gigavac/index.htm - gigavac have a nice range of well packaged contactors (I think we we should standardise on using these within our systems - Philip)
• High Voltage
