The motor converts electrical energy into mechanical kinetic energy according to the magnetic effect of current. For a DC motor, the speed of the motor varies with the input voltage. Tesla drives the motor and makes car move through electric energy of the battery. Motor Driver Card's main function is to control the speed and direction of the DC Motor through the circuit, so as to make mechanical car move forward and backward, speed up and down.
In addition, Motor Driver Card can also control the movement of the stepper motor. Stepper motor is based on the principle of electromagnet, in which the rotating structure can be quickly adjusted to a specific position within the range of angles. It is widely used in the design of robot kinematic joints and mechanical arms. Motor Driver Card helps you control the stepper motor circuits freely. By adjusting the frequency and number of pulse signal, it is allowed to control the speed and displacement of stepper motor, and achieve the required motion.
Motor Driver Card features LV8548MC, which is a 2-channel motor driver IC. It can drive two DC motors or one DC motor using the parallel connection, or it can drive a stepper motor in full-step and half-step.
