DC Motors

Keyword Definition
Brushed Motor A type of DC hobby motor that uses brushes to transmit electrical current to the rotating armature.
Current The flow of electric charge in a DC hobby motor, measured in units of amperes.
DC Hobby Motors Small electric motors used in hobbyist projects that are powered by direct current and suitable for various applications such as model cars, boats, and planes.
Motor Drivers Integrated circuits or modules used to control the speed and direction of motors.
Motor Shield An expansion board for a microcontroller that provides additional features to control motors.
Overcurrent Protection Safety feature that prevents damage to motors by cutting off power when current exceeds a set limit.
PWM Pulse-width modulation, a method of controlling the speed of a DC hobby motor by varying the average power delivered.
Stepper Motors Motors that move in discrete steps, commonly controlled by motor shields for precision movements.
Torque The rotational force produced by a DC hobby motor.
Voltage The electrical potential difference that drives the current in a DC hobby motor, usually measured in volts.
