However, in this case, the output of the 555 is connected to a MOSFET which is used to vary the speed of a computer fan motor.

The A4933 from Allegro MicroSystems is an automotive-grade 3-phase MOSFET pre-driver IC for the control of brushless DC motors in applications such as electronic power steering systems, engine cooling ...

The DC motor speed control project is intended to manage the pace of a DC motor by means of an 8051 sequence micro-controller. The pace of DC motor is straightforwardly relative to the voltage ...

This paper presents a DC motor speed controlling technique under varying load condition. The linear system model of separately excited DC motor with Torque-variation is designed using PID controller.

He hooks up the SN754410 to two motors, giving him speed and direction control for both based on the duty cycle of a PWM signal entering the chip for less than $2.50.

The circuit in the figure provides three levels of speed control for a dc motor, using a PC’s parallel port (LPT1). A C++ program performs the control functions by allowing the signals from the ...

How is current regulation applied in dc motor drivers? Oftentimes, the motor driver and power supply are burdened by large currents upon starting a dc motor.
