Electrical motor control circuit diagrams and electronics projects
Electrical motor control electronics projects with circuit diagrams for stepper motors, dc motor, ac motor using simple and complex technology.
PWM controller and other circuits based on electric motors .
Using L297-L298 integrated circuits manufactured by SGS Thomson (ST) can be made a control circuit for a stepper motor with two phase bipolar or unipolar four-phase (maximum current allowed on stage is 2 A).
This integrated motor driver generates control signals for the double stator and allows selection of travel direction and execution of a full step or half step, through proper planning its inputs, TTL compatible.Control of current good results because it allows the stepper motors to be connected to a voltage higher than that allowed for the command voltage.
Using this controller can be designed a speed controller regardless of the load. The electronic speed regulator can be used to control speed of drilling machine as the load grows, tcem Drilling of the machine decreases, while the current increases.
