Too much or too little friction can cause problems in a motion control system, making it harder for servo drives to do their jobs. High friction motors pose a control problem for machines, as the current required to overcome the stiction element of the motor may then exceed the desired command and result in position … Friction

The maximum rate of change in current (di/dt) is dictated by the bus voltage V and the motor inductance L, where di/dt = V/L. A minimum amount of inductance is required for a stable current loop. Issues Too much motor inductance can make the current loop sluggish, leading to difficulties during the tuning process and … Inductance
