Stepping Motor (continued)
Driver Circuit (driver)
The driver circuit of a stepping motor consists of a logical section which forms and distributes a pulsed signal from an
oscillator and an amplifying section which amplifies and supplies the signal to the motor.
Stepping motor principle (if 1st - phase is on drive)
The wound phases of
A
,
B
and
C
are rolled on the stator.
When a pulse enters
A
phase, rotor is in (1) condition and A-a, A-c are energised. The excitation of
A
phase breaks down and
then the pulse of
B
phase enters, B-b, B-d are energised and results in (2) condition. When the rotor rotates in a counter
clockwise direction it sets up the condition (
A-B-C
). When a pulse is registered in the order (C-B-A) the rotor is rotating
clockwise.
