CLV permanent magnet synchronous motor control technology is widely recognized

2021-07-17

The R&D team has professional EMC design, development, testing and rectification experience. The inverter can be built with high standard EMC filter circuit, which can meet the national standard GB4824 1 group CLASS A standard limit (corresponding to the European standard C2).

CLV drives are designed for permanent magnet motors. Open-loop control requires no encoder, enabling users to achieve the benefits of motor energy efficiency without incurring encoder costs.

For permanent magnet synchronous motor, we have independently developed a sensorless algorithm, low speed with adaptive dead zone compensation algorithm, can achieve zero speed full load start.

For the permanent magnet fan industry, we have perfect up-wind starting algorithm, bus overpressure suppression algorithm, constant air volume algorithm, blocking detection and so on.

We provide quality FOC control solutions, so that the motor operation is quieter, more stable, more energy saving, more smooth.
