Stepping motor group control circuit

摘要

The control circuit has a respective control stage (4.1,...4.n) for each stepping motor (2.1,..2.n) within the motor group, positioned in the vicinity of the stepping motor and coupled via signal lines (4,5) with a central control device (1). The signal lines include a common clock signal line (4) for all the control stages and a rotation direction signal line (5), each stepping motor and control stage coupled to the central control device via a respective voltage supply line (3.1,...3.n), with selection of the stepping motors by switching the supply voltage.
