ABSTRACT:
A control low simulator device for testing a stepper motor with N windings. The device has a digital signal generator stage constituted by a computation unit having a central unit to which are connected an input/output peripheral device module for use by a user, a memory module and a clock module of frequency f. A plurality of at least N identical triggerable memory units are connected in parallel to the computation unit and controlled by the clock module and each drive an identical digital-to-analogue converter. The memory units are adapted to contain cyclic sequences of m signal values of period n, substantially identical from one memory unit to another except for an offset representing one step. The control low simulator device also has an analogue power or driver stage constituted by a plurality of N identical voltage/current converters, each connected to the output of a digital-to-analogue converter and adapted to have its output connected to one winding of the stepper motor, to apply thereto a signal of frequency f
