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…
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…

unipolar stepper motor drives, bipolar stepper motor drive circuits, control and power supply cards that will benefit CNC Projects … High power designs as well as low power motor drive circuits features. Schematic and PCB printed circuit diagram of CNC Circuits Drawing source with eagle cad There are files. 8-lead relay with 10 amperes relay…
Motor Control Circuit design and regeneration of a three – phase inverter for supplying an asynchronous motor. The inverter is designed to drive a rack drill with approx up to 1 kW. The device will be constructed using integrated circuits. Single-purpose integrated Circuits simplify the design and manufacture of low-cost applications. And thanks to that…
The L298 is an engine driver with two H-bridges. It can control two DC motors or one bipolar 4-wire stepper motor. Its main advantage is a large power supply voltage range (up to 46V) and high L298 maximum load currents: 2A continuous, 3A instantaneous. In addition, the voltage has been applied to the CON1 connector,…
DRV8402 Motor Driver Circuit The main component is the microcontroller dsPIC30F2010, who for its activities needs outside of the power supply voltage also a source of accurate clock pulses. In order to achieve the speed of 30 MIPs, we had to calculate the speed of the desired crystal. Each instruction takes four bars of the…
Hi friends, DC motor control I’m doing a study on. As part of this study, a DC motor H-Bridge I need to drive. Bread on the board, IR2101 an H Bridge consisting of MOSFETs IRFZ44N and I built it. But the mosfet heatsink on the MOSFETs a 3-4 because it is not burned. interruption also…
An interesting CNC project author’s own and meet the needs of CNC-drilling machine made of wooden material is made up largely mechanical part of the CNC machine control card with chip uln2803 and stepper motors, LPT port connection is being used for classic 74hc14n 74HC14N IRF520 mosfet is controlled by the drilling drill again driven…
