The Links below are for a comma seperated table for amps vs. torque, and
RPM vs. Torque vs. Voltage. These tables can be loaded into any spreadsheet
program which excepts a comma seperated tables.
The Links below are for Motor physical specifications. They are either in HTML
format or PDF format.
Someone please help me get these.
Motor Amps vs. Torque
This form calculates k and n for the equation:
torque = k * current^n
Enter values for torque and current from the motor graph and then click on the calculate button.
Have patience, it takes a while (up to 5 minutes).
Motor RPM vs. Torque vs. Voltage
This form solves the equation:
voltage = (rpm * d)/((a /(torque^b)) + c).
Enter values for the voltage curve you are calculating (use the highest voltage cureve you have).
Then enter values for torque and RPM. You must specify a torque and RPM for each value.
Have patience, this takes a long time.
I you have any information to fill in my chart or have other motor you want
to add to the chart, please email me at
Uve.Rick@usa.net. Please provide the
following information: HP, Weight, Amp vs. Torque graph, and Amp vs. RPM vs.
Torque graph. Equations would be really nice, I can't guarentee when I will
come up with the equations. I'll put these equations in the ev calculator as
soon as possible.
Acknowlegements:
I would like to thank Gray Flo at innEVations for supplying the motor curves
for the kostov, XP-1227 and XP-1263 motors.
