<W1-2 Phase Excitation>
1. Overview
W1-2 phase excitation is a technique for acquiring 1/2 the step angle of the 1-2 phase excitation by controlling the
stepping motor winding currents for each phase.
2. Basic Concepts
There are three types of W1-2 phase excitation.
A: Fixed common current form
B: Square form
C: Circle form
Figure 10 shows the concepts behind these forms.
The relation between the basic step angle
θ
O
of a two (or four) phase stepping motor and W1-2 phase excitation is
given by the following formula.
θ
=
θ
O
/4
In A, the common current is always a fixed value, and the motor vibration is even lower than for 1-2 phase
excitation since the motor current in each phase increases in a stepwise manner.
In B, the common currents is 2-times or 1.41-times, and although the motor current in each phase increases in a
stepwise manner, operation is rougher than type A.
In C, although the common current still increases, since the motor current in each phase increases in a stepwise
manner and the form is circular, this type is effective at reducing vibration.
3. Application
Figure 11 shows the timing chart for each block, i.e., the input clock, the each phase driver input, current control, and
the phase currents. Based on the clock, which is the rotate command for the distributor first stage, this circuit controls
the fixed current drive currents by forming each phase input as a 1-2 phase excitation sequence and forming the
current control sequence as C1, C2, and C3 in the distributor.
