The equation for current vs. torque is: Torque = k * i^n.
The equation for voltage vs. torque vs RPM is: V = (d * rpm)/((a/(torque ^ b)) + c).

    The link below is for a comma-separated table for amps vs. torque, and RPM vs. Torque vs. Voltage. This table can be loaded into any spreadsheet program which accepts comma-separated tables.

    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.
