    1. Copy and paste the identified parameter with lab02 from the Watch Window into the corresponding #define statements of motor parameters in user.h.
    2. Using lab10a to run the motor, add the "gMotorVars.Vs" and "gMotorVars.OverModulation" in Watch Window, to check if the value of both variables is very close. If yes, that means the input voltage is not enough for running the motor to such high speed. So you might increase the input DC bus voltage or implement the field weakening control as lab09.
