ABSTRACT:
A circuit for the control of a stepper motor having a rotor configured as a permanent magnet and a stator configured of at least first and second energized excitation coils enclosing the rotor. Each end terminal of the first excitation coil is connected to the positive pole of the supply voltage over a switching element and each end terminal of a second excitation coil is connected to the negative pole of the supply voltage over a switching element. The central contacts of both excitation coils are connected to each other.
