The Typical Application
(Continued)
ONE-PHASE-ON FULL STEP DRIVE (WAVE DRIVE)
To make the motor take full steps, windings A and B can be
energized in the sequence
A
→
B
→
A
*
→
B
*
→
A
→
…,
where A represents winding A energized with current in one
direction and A
*
represents winding A energized with current
in the opposite direction. The motor takes one full step each
time one winding is de-energized and the other is energized.
To make the motor step in the opposite direction, the order of
the above sequence must be reversed. Figure 7 shows the
winding currents and digital control signals for a wave drive
application of the typical application circuit.
TWO-PHASE-ON FULL STEP DRIVE
To make the motor take full steps, windings A and B can also
be energized in the sequence
AB
→
A
*
B
→
A
*
B
*
→
AB
*
→
AB
→
…,
and because both windings are energized at all times, this
sequence produces more torque than that produced with
wave drive. The motor takes one full step at each change of
direction of either winding current. Figure 8 shows the wind-
ing currents and digital control signals for this application of
the typical application circuit, and Figure 9 shows, for a
single phase, the winding current and voltage at the output of
the associated current sense amplifier.
