MEASURING MOTOR PARAMETERS
The inertia is then the acceleration torque divided by the acceleration as stated above. BLDC MOTORS- The tests described thus far must be modified for a bldc motor. A bldc motor must be tested with its servo amplifier. The step input will be a step in dc voltage to the servo amplifier input. The voltage step should be large enough to cause the

ELECTRIC SERVO MOTOR EQUATIONS AND TIME CONSTANTS
support.controltechnologycorp.comIn the analysis of electric servo drive motors, the equations for the motor indicates the presence of two time constants. One is a mechanical time constant and the other is an electrical time constant. Commercial servo motor specifications usually list these two time constants. However, it should be cautioned that these two time constants as ...
