NTE1885 Datasheet (NTE) - Integrated Circuit Module / 4 Phase Stepping Motor Driver

NTE1885, Integrated Circuit Module / 4 Phase Stepping Motor Driver

of Operation: Constant Current Chopper Drive a) When the phase drive input is activated, the motor winding current increases.

At a predetermined current (the rated current of the motor), the applied voltage of the winding begins to be switched ON *OFF to maintain a constant current.

This is t
