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…
The BLDC motor control circuit based on the STM32F405RG has a highly developed design. All materials except power solids capacitors are in SMD type. Power Mosfets ipt007n06n is a difficult circuit design but it can be useful for similar projects. 8-layer PCB drawing file prepared with source code and Kicad was shared. Sensorless vector control…
Unipolar Step Motor driver circuit up to 20A. It works with maximum power 20A, Maximum 100V, Over temperature protection, Half step and full step operation. Unipolar Stepper Motor Driver circuit L297 integrated on L297 integrated circuit is powered by mosfets and high power motor version is provided. Tests were done in the workshop with Mach…
350W Scooter of Electric Motor Scooter control unit, max. It can power 500W. Input voltage 36V DC (can be used with 20V… 50V.) Scooter Motor Control works on the principle of motor winding as a switched power supply and coil. In forward driving, the unit acts as a downstream converter and controls the current to…
Solenoid valves are devices widespread in industry and outside. The indisputable convenience of use is paid for by the considerable power consumption of the coil, which – obviously – heats up to a significant temperature, while high force is needed only during the movement of the core in the electromagnet. The presented system allows to…
Electric motors, in addition to many obvious advantages, also have some disadvantages. One of them is the consumption of a much higher current during start-up compared to the current consumed during normal operation, which can overload the power supply. The schematic diagram of the “soft start” system is shown in figure. The multivibrator with the…
