phase stator winding. – Winding as is assumed distributed in slots over the inner circumference of the stator, which is more characteristic of the stator winding than is a concentrated winding. – The winding is depicted as a series of individual coils. Each coil is placed in a slot in the stator steel. – Follow the path of positive current i

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:
