For a 1-rad/sec step reference, the design criteria are the following. Only difference is that and additional motor driver circuit using a transistor is included in the circuit. Thus, the magnitude of E b can be given by EMF equation of a DC generator. Please tell me this can be done. https://www.youtube.com/channel/UCG56GKqVYDZQHdEIw... Did you make this project? Wiring a variable speed motor is the same as wiring a single speed motor, as the speed control function is an integral part of the motor. The NE555 is rated to 15V, so battery voltage shouldn't be a problem (A resistor/zener diode combo can be used on the input to bring it down to 12V if you're concerned about that.) My grand daughter has an electric car.............but it has no speed control.......which is a bit scary. Servos, have few advantages over DC motors: High Torque; Low speed; Precision control; One problem with servos is that they cost a lot more than DC motors. The proper speed control product can be selected according to the function, the performance, the cost, and the purpose desired for your application. this is the thing I have been looking for.

I showed you how to control the dc motor speed with nodemcu WiFi module and l293d h bridge motor driver. Soon I needed to control 24 V motors, so I had to come up with a design I can use for the work. If we add resistance in series with the armature, the armature current (Ia) decreases and hence speed decreases. Make the Schematic, PCB. a ¼HP 12V motor will draw a lot of current. External resistance in armature circuit Ra. PWM DC Motor Speed Controller, DC10-55V/60A Stepless DC Motor Speed Controller with Forward-Brake-Reverse Switch Adjustable Potentiometer and LED Display. Speed of a dc motor is directly proportional to the back emf E b and E b = V - I a R a.That means, when supply voltage V and the armature resistance R a are kept constant, then the speed is directly proportional to armature current I a.Thus, if we add resistance in series with the armature, I a decreases and, hence, the speed also decreases.
