From October 1, 2015, Nord Drive Group will change its design and install new and more flexible microcontrollers and firmware in all motor and cabinet-mounted converters. It is noteworthy that this structural upgrade enables the frequency converter originally designed for asynchronous motors to control synchronous motors. With the advent of IE4 high-efficiency and energy-saving motors,

According to the circuit characteristics of Ck topology, this paper presents the design and Simulation of power conversion circuit for solar energy controller based on Ck topology. Firstly, the maximum power point tracking strategy is discussed and analyzed. Then the theoretical study of Ck topology structure is introduced. On this basis, the circuit parameters are

Aiming at the problems of large volume, low control precision and difficulty in field calibration and maintenance of hydraulic valve controllers currently used in the market. An intelligent electric actuator for hydraulic valves based on 32-bit embedded RISC microprocessor with ARM core is designed. Compared with the traditional hydraulic valve electric actuator, the practical application

Aiming at the shortcomings of the current ship navigation signal lamp controller, such as poor universality, low information level and inconvenient installation and use, a new type of general ship signal lamp controller is designed. This new type of controller has the secondary programming function similar to PLC, and can be applied to different requirements

In order to meet the power demand of electrical appliances, improve the level of electrical insulation and ensure the reliability of the circuit, families often purchase high-quality multi-core soft copper wires with large cross-section for wiring, which not only improves the reliability of electrical insulation and lines, but also costs a lot of decoration costs.
