Brushed DC Motors
Brushed DC Motor Control
Brushed DC motors are easy to control because speed and
torque are proportional to the applied voltage/current. The
rotor is heavy due to windings on the armature, more inertia
makes it more difficult to start/stop. Heat is generated in
windings on the rotor and is more difficult to remove.

Brushed DC Motor Development Tools
F1 BDC Motor Add-On (DM164130-6)
The BDC Motor Add-On is a simple
development accessory that plugs
directly into the F1 LV Evaluation Platform
and incorporates all the components
necessary to implement Brushed DC
motor control. Key features include
two MOSFET half bridge circuits, motor current limit
adjustment, debug header, and pin header connector for
the motor and power supply.
MTS2916 Dual Full-Bridge Stepper Motor Driver
Evaluation Board (ADM00308)
The MTS2916A Dual Full-Bridge
Stepper Motor Driver Evaluation Board
demonstrates the capabilities of the
MTS2916A to control both windings of
a bipolar stepper motor. The board also
demonstrates the capabilities of controlling two brushed
DC motors.
