inverter

The high-voltage four-quadrant (hoist) inverter adopts advanced vector control technology. At the same time, vector control without rotary encoder can be used according to the site conditions. The main difference between vector control and traditional V/F control is that vector control can The reactive current is distinguished from the active current (torque current). During the lifting process, the active current can be automatically adjusted according to the change of the load to make the output torque reach a better working condition, and the output torque can be 2.5 times of the rated torque.

JD-BP37/38 series of high-voltage variable frequency speed regulation system, with high-speed DSP as the control core, adopts space vector technology, power unit series multi-level technology and other advanced control technologies, with high reliability, easy operation, high performance, small size The volume is the design goal to meet the needs of users for various load speed regulation, energy saving, and production process improvement. It is a high-high voltage source inverter. Its harmonic index is much smaller than the national standard of IEE519-2014, the input power factor is high, and the output waveform quality is good. It is unnecessary to use input harmonic filter, power factor compensation device and output filter; there is no additional heating and motor caused by harmonics. Torque pulsation, noise, common mode voltage and other issues can be applied to two/four quadrant synchronous motors (including permanent magnet synchronous motors) and asynchronous motors.
