Programmable Peripheral
Application Note 042
Four Axis Stepper Motor Control Using
a Programmable PSD5XX MCU Peripheral
from WSI, Inc.
By Nasser Pooladian, Data Card Corp.
Introduction
The design of a stepper motor control requires various timers and electronic controls. This
application note explains the basic operation of a stepper motor. It also presents the theory,
implementation and electronic control of a four axis stepper motor control using the
PSD5XX family of products from the WSI Inc. The PSD5XX, as a field programmable
microcontroller peripheral device, provides a high degree of integration on the embedded
controller design. Configuration of the memory, ease of interface to various different
microcontroller buses, interrupt handling, I/O ports, and four sixteen bit counter/timers make
this device a great candidate for embedded applications.
A stepper motor is basically a rotational actuator which rotates a fixed anglewhen excited.
A stepper motor can be directly controlled electronically without the need for a feedback
element (encoder, tachometer feedback, etc.) as required in servo applications. The simpler
drive and control electronics needed by a stepper motor makes it a good candidate for a
positioning actuator in many different motion control applications. Several different types of
stepper motors are used in the industry.
A hybrid stepping motor is used in this application. The rotor and stator are multi-toothed in
a hybrid stepping motor and the rotor is magnetized in the axis of the rotor shaft. When
properly driven, a hybrid stepping motor will step 1.8 degrees in the full step mode and 0.9
degrees in the half step mode. Figure 1 shows a typical hybrid motor.
