Electronic Distributor for 4-Cylinder Internal Combustion Engine

| 2022/07/01

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…

Electric Bicycle BLDC Motor Control Circuits 500W 1000W

| 2022/02/27

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…

Solenoid Coil Power Reducer Circuit

| 2019/12/08

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…

Soft Start Circuit For DC motors

| 2019/12/08

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…

NE556 Speed controller Circuit DC Motors

| 2019/06/16

The circuit is designed for DC 12V motor and has been tested with miniature drill BOSCH MBM04. Because they can take motor from the source of higher currents, it is appropriate their drive speed pulse while maintaining maximum Tension. Unlike speed control by changing the voltage it has a pulse-width application modulation advantage lower power…
