Understanding DC Motor Controllers
DC motor controllers are devices that manage the operation of DC motors by controlling the voltage and current supplied to the motor. They serve as intermediaries between the power source (like lithium batteries) and the motor, enabling precise control over speed, torque, and direction.
How DC Motor Controllers Work
At their core, DC motor controllers use various methods, such as Pulse Width Modulation (PWM), to regulate the power sent to the motor. PWM involves switching the power on and off at a fast rate, effectively controlling the average voltage and current. This technology not only enhances efficiency but also protects the motor and battery from damage due to excessive load.
