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.
