What are DC motor controllers and what are they used for?
In the chain of electromechanical drive systems, the DC motor controller is a device constituting an intermediate link between the control system and the supply voltage source and the motor. The control system is increasingly based on a previously programmed microcontroller and its task is to send appropriate control signals necessary for the proper operation of the engine - particularly important here is the adjustable pulse width (PWM) signal, which influences the direct current consumed by the engine in terms of its average value over specific time intervals, which translates into the correct setting of the output power on the engine shaft and its rotational speed. Due to the fact that most microcontrollers available on the market have a limited output current of several dozen milliamps, and DC electric motors are characterized by a rated current consumption from several to even several dozen amperes, it is necessary to use an intermediary system, in the form of a special controller that solves problem of regulating the flow of current supplying the motor.
Drivers with high current efficiency and great possibilities of cooperation with external equipment
The DC motor controllers offered by the Botland store can be used for both motors with metal and plastic gears. Our assortment includes controllers with a wide range of operating voltages and currents tailored to the needs of your project. Most often, the DC motor control module is based on an H-bridge in the form of an integrated circuit or a discrete one - based on MOSFET transistors, and its control is carried out via an interface that includes a set of digital input/output ports, including PWM signal generation, thanks to which you can easily connect your DC motor controller with a module containing a microcontroller - also for the needs of such an application, you can purchase dedicated Arduino shields from us, but it is also possible for the driver modules to work with other platforms based on microcontrollers as general-purpose motor controllers. Additionally, the Botland store offers DC motor controllers compatible with Raspberry Pi computers. In line with today's requirements regarding cooperation between peripheral systems, the DC motor controllers we offer are adapted to communicate via USB, UART, I2C or TTL interfaces.
