Circuit board for controlling biphase bipolar stepping motor for rotor spinning machine, has converter circuits transmitting signals inverted relative to two respective inputs of board to respective inputs of motor drive

摘要

The board (1) has converter circuits converting signals of digital inputs (3-6) of the board into signals for a motor drive (9). The circuits transmit a signal corresponding to an input of the board to a first input of the motor drive. The circuits transmit a signal corresponding to another input of the board to a second input of the motor drive. The circuits transmit a signal inverted relative to the latter input of the board to a third input of the motor drive. The circuits transmit a signal inverted relative to the former input of the board to a fourth input of the motor drive. An independent claim is also included for a rotor spinning machine.
