Stepper motor gives a simple, low cost, and accurate position control. Stepper motor can be driven by circuit mounted close to the motor, and controlled by a remote control circuit through long cable.  The interesting thing of this circuit is that the power for both motor and the driver circuit is carried over two wires, [...]

This is a video of stepper motor control. This video shows how the LMD18245 can control the 9.2v stepper motor. The supply that is needed for stepper motor is 9.2 V. In this video, two LMD18245 are used to control the speed and direction. Here is the video :

Stepper motor controller is needed to run a stepper motor, since a stepper motor cannot work by just connecting it to a power supply.  To program a stepper motor to make a complex movement, we usually need a micro controller. Fortunatelly, for a simple movement like just rotating eith a constant speed, we can use [...]

Speed control for dc motor (electric motor) can be implemented using open loop or closed loop. Closed loop controller, also known as servo controller,  or a feedback control, gives the best performance since the loop will maintain the actual speed to follow the reference. In simple application, an open loop controller can be enough if [...]

Electric motor has been widely used as motion control, and many  type of motor controllers  have been designed to provide variable speed drives for the motor. The best controller is the servo controller, where a precise speed control is implemented using a speed sensor in the feedback path.  The circuit of the motor controller in [...]

This is a video tutorial of DC motor control. This video shows how to control the DC motor speed. In this video, speed of the DC motor is controlled by changing the power supply. Increasing speed can be done by increasing the voltage, and decreasing the voltage will decrease the speed of DC motor. Here [...]
