Question

Difference between mechanical Era and electro mechanical era​

Answer 1

Answer:

The electromechanical time constant is the time needed for servo to speed up from zero to a nominal no load speed, with stall torque acting and no load torque present on the shaft.

The mechanical time constant is the time needed for servo to speed up from zero to a nominal speed, with nominal torque acting and no load torque present on the shaft.

The electrical or armature time constant is the ratio of armature inductance L and resistance R, and it is not directly related to electromechanical or mechanical time constant.
