Features
BI-POLAR CHOPPER STEPPER MOTOR CONTROL MODULE
Test 1
Develops maximum possible motor torque by using
dual coil-current sensing & control loop circuits
Allows use of drive voltage beyond rated motor
specification for enhanced torque & speed
Chopper drive circuitry is current adjustable up to
2 Amps/coil using dual internal 5W sense resistors
Motor supply voltage 0V to 46V
Integral heatsink system and thermal potting
compound eliminate need for an auxiliary heatsink
or fan
Eight internal 3A Schottky clamp diodes and large
filter capacitors for enhanced noise suppression
Two modes of current chopping provide efficient
operation of both large and small stepper motors
Internally generated voltage source for easily
setting maximum coil current
Primary drive circuit thermal overload protection
Standard 24 pin DIP pin spacing for easy PCB
placement & prototyping
Threaded mounting coupler allows secure mount
to PCB in rugged applications
Chopping frequency generated internally;
externally generated frequency may also be used
Overview
The EDE12400 stepper motor control module offers
designers a compact, reliable stepper motor control
system. Engineered with internal and external
heatsinks and a highly thermally conductive potting
compound, the need for cooling fans (known for short
lifetimes) or a large heatsink plate is eliminated. An
integrated chopper drive circuit safely provides the
maximum motor torque for a given drive voltage,
even one many times over the manufacture-specified
voltage, offering tremendous torque and speed
improvements over traditional stepper motor control
circuits. Maximum coil current is easily set using a
potentiometer or voltage divider, and can be
dynamically adjusted. The highly efficient design of
the EDE12400 drive circuitry combined with its unique
PowerCube™ package makes it the ideal motor
control solution for nearly any application.
