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 Application Notes Algorithm App Note PIC18CXX/PIC16CXXX DC Servomotor Applications AN8696 Low-Cost Bi-directional Brushed DC Motor Control Using the PIC16F684 AN893 Brushed DC Motor Fundamentals AN905 Brushed DC Motor Training Class Title Language Recording Date Duration Brushed DC Motor Basics English 09/18/2008 14 min. 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.
