Jun 27, 2020 · Learn the basics of DC motors - how they work, and how to control them with PWM, H-bridge motor drivers, and the L293D motor driver.
Feb 11, 2021 · The speed of a DC motor can be controlled by adjusting the voltage applied. This is because the speed and load torque of a DC motor is inversely proportional, and this translates with changes in drive voltage.
The speed of a DC motor can be controlled by varying the voltage, using series-parallel control, changing the magnetic flux, or adjusting the resistance in the armature circuit. A DC motor is an essential device that converts direct current (DC) electrical energy into mechanical motion. It plays a crucial role in various applications.
