Brushless synchronous AC generator and diesel engine crankshaft coaxial installation, you can use the rotary diesel engine driven generator rotor, the use of 'electromagnetic induction' principle DSE520 controller, generator will output induced electromotive force, the load circuit can be closed generate electricity. Diesel generator driven by the internal combustion engine generators. It start quickly DSE520 deep sea, easy to operate. But the high cost of power generation internal combustion engine, so diesel generator is mainly used for emergency standby power, or in the flow of power stations and a number of large power grids have not yet reached the area. Diesel generator speed normally produced at 1000 rev / min or less DSE520, capacity between a few kilowatts to several thousand kilowatts DSE520, especially below 200 kilowatts unit used more often. It is relatively simple fabrication. Diesel output shaft torque pulsation periodically, so the generator is working under the conditions of severe vibration. Thus, the structural components of diesel generators, in particular the shaft should have sufficient strength and rigidity to prevent breakage due to vibration of these components. The controller Maintenance: When electric car brush controller does not output a) the Meter +20 hair (DC) position, the first measurement of the gate of the high and low potential of the output signal. 2) as pinching the brake, the brake signal has more than 4V potential change, you can rule out the gate to malfunction. 3) Then follow on foot brush Controllers Common menu morals, and the measured voltage values ??morals people master logic chips for circuit analysis and check the value of each chip peripheral components (resistors, capacitors, diodes) whether and components identify surface consistent. 4) Finally, check the external devices or integrated circuits fails, you can replace the same type of device troubleshooting. DSE520 deep sea, deep sea controller (certified), DSE520 provided by the Dongguan City, South City Zhongxin Electrical and Mechanical operation. Dongguan Nancheng Zhongxin Electrical and operating (zhongxin888.net.cn) Dongguan, Guangdong, industrial products leader, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In Zhongxin Electrical and Mechanical leadership with the staff warmly welcome all inquiries negotiations to create a better future for electromechanical faithful.
