From the fault diagnosis to predictive maintenance

With the continuous development of machine safety standards, the traditional fault diagnosis and protection technology (to judge when the problem happened cause and measures to prevent failure expansion) has been out of style, the latest product into the predictive maintenance technology, make people can through the Internet trends in the dynamic of important technical parameters in time, and take preventive measures.

Changes such as: focus on the increase of current, load, peak current, shell/core temperature monitoring temperature sensor, and alert to any current waveform distortion.

Specialty and diversification

Although there are on the market generalization of wind grid tie inverter products series, but for some specific applications specially design and manufacture of servo system.

Using magnetic material different performance, different shapes, different surface bonding structure (SPM) and embedded permanent magnet (IPM) rotor structure of the motor, split type iron core structure is used in Japan makes the permanent magnet brushless servo motor production implementation of high efficiency, large quantity and automation, and cause a domestic manufacturer of research.

Miniaturization and large scale

Permanent magnet brushless servo motor and stepper motor are positive to smaller the size of the development, such as 20,28,35 mm outer diameter; Also in the development of more powerful and the size of the model, has seen 500 kw permanent magnet servo motor.

Reflecting the development tendency to heal.

The design of underground LED lighting solution

OFweek semiconductor lighting network - based on the current problems existing in the subway micro grid tie inverter underground lighting design, lighting distribution, parameter calculation, system optimization, more energy efficient LED lamps and lanterns of choose, etc, put forward Suggestions on the optimization design, and applied in the actual design and good design results have been achieved.
