In applications for external starting of the washing machine engine, the biggest missing torque is the lack of power control, starting the engine by applying direct voltage only provides speed, and the engine stops at the slightest strain. There are circuits using the TDA1085C universal motor speed control integrated for full control. TDA1085 is an…
SG90, SG-5010 etc. You can control 24V DC Motor using the Mini Servo Motor driver. PC817 opto couplers and then IRL2203N mosfets are connected to the outputs of the motor driver module. The motor is driven by PWM signal. The circuit was used for steering control of the electric bicycle. 24V DC motor ZGB70R-60SRZ-1 with…
You can use IR2104 MOSFET full bridge motor driver circuit in your high power motor projects. There are DIP and SMD version PCB drawings of the circuit. 7400 NAND gate IC is used in the signal input. The author faced many problems while implementing this project. An important detail is that if the supply voltage…
The high-power control circuit motor reversing DC motor speed controller circuit features soft start, relay switching of motor direction, and PWM speed control. I have shared the circuit before. There are details in the article “High Power 30 Amp DC Motor Speed Control Circuit”, but I prepared a new article because I applied it and…
The electronic control circuit for the 4-cylinder internal combustion engine is designed for 4-cylinder internal combustion engines to work with both the external switch, the ignition unit and the ignition coils using the built-in high voltage switches. There is a universal “DH” input for connecting a Hall sensor or a breaker contact. The U2 LM555…
A few months ago, a friend said that the electric bicycle brain was faulty, so I said bring it and we’ll see. High power BLDC motor control documents can be useful for code repair or project development. There is also a 250w 36v electric bike motor control scheme made in China. The explanations below are…
UC3844 is popular current mode PWM controller which is commonly found on DC to DC converter circuits and switch mode power supplies. This pwm motor speed controller is also based on UC3844 and it is specifically design to drive 20VDC 24VDC motors. In this given DC Motor Speed Controller configuration UC3844 50kHz to 240kHz PWM…
A motor driver circuit designed specifically for robotic projects using high power collector motors, with or without PWM modulation with a Microcontroller or debug card, to fully control two motors. The drive is made with a symmetrical dual channel digital controlled circuit. It allows you to change the axis rotation direction independently for two motors,…
