Description
MOTOR.KEdefines the back EMF constant for the motor. The back EMF constant defines
how much voltage is generated at the motors coils. The relationship between MOTOR.KE and
speed is described by the following equation:
Coil Voltage = MOTOR.KE * VL.FB
Where:
VL.FB is in units of krpm for rotary motors and in units of m/s for linear motors
