ELECTRIC SERVO MOTOR EQUATIONS AND TIME CONSTANTS
support.controltechnologycorp.comFrom the last equation, the motor mechanical time constant, tm, is: tm = e T a T K K R J [sec] (15) The total inertia, JT, is the sum of the reflected inertia to the motor shaft plus the motor inertia. The resistance, Ra, is the motor winding resistance plus the external circuit resistance. Thus the motor mechanical time constant is summarized as:

These fast risetime surges result in a non-uniform distribution of the impulse voltage across the winding components [7 to 10] with the turns in the first
