Default AC Motor Selection

AC motor selection differs from DC Motor Selection because AC controllers may require a matching motor. In fact, most AC motors marketed for EVs come with a controller. These controllers often (but not always) include a built-in charger and DC-DC converter. Below is a list of AC motor and speed controller combinations.

Industrial VSDs usually have a smart "learning" feature to configure itself for a particular motor and can therefore be used almost universally with 3 phase induction motors and in some case permanent magnet synchonous (BLDC) motors. No parameters need be entered apart from torque/current limit, etc. The VSD simply spins up the motor with no load on the shaft and records it's own parameters. The VSD must support variable torque control and have access to the DC bus for connecting to the battery pack. Be aware that the VSD manufacturer may not warranty their product if used in an EV.

Notes For Reading Chart:
All voltages are given in RMS Voltage. If you wish to calculate the battery pack voltage necessary, simply multiply the desired or stated RMS value by 1.41 or sqrt(2).
Take the power figures as a guideline only. Most induction motors may be overpowered above their base speed by using a higher pack voltage, extending the constant torque region.
Remember, power (Watts) is the product of torque (Nm) multiplied by speed (rads/s or RPM/9.55). Power figures are stated for the motor's base speed, not the maximum speed.

Notes for Adding Motors:
If you are not comfortable in editing this wiki then post the information in the forums so they can be transferred to here.
These motors are ranked according to their power at their maximum voltage. Statistics would vary using smaller voltages.
I have sourced the information for the Siemens AC induction motor from
http://www.metricmind.com/audi/main.htm
For imperial and metric conversions just google a converter.
Hope you find this useful
