Better technology, energy saving and upgrade

AC330 series inverters have developed a new and optimized MTPA algorithm to adapt to the high-efficiency drive of synchronous reluctance motors in the market. The dq axis stator current can be optimally distributed to minimize the stator current, thereby minimizing the stator copper consumption and achieving the best electrical operation efficiency.

Better technology, energy saving and upgrade

In addition, matching the new generation of energy-saving control technology can realize the efficient operation of induction motors. According to the load situation, it automatically adjusts energy-saving, two-pronged approach, maximizes the motor efficiency, and reduces energy loss.

Market test statistics compare asynchronous motors. Underrated conditions, the system loss of driving synchronous reluctance motors is reduced by about 40%, and the efficiency at the rated point is increased by about 5%. The load rate is less than 50%, and the energy-saving effect is particularly obvious.

Excellent low frequency characteristics

AC330 drive synchronous reluctance motor speed regulation ratio is 50:1 (when the synchronous reluctance motor rated frequency is 50Hz, 1Hz can drive full load). It can effectively make up for the insufficiency of the low-frequency drive of the synchronous reluctance motor. Ensure that the low-frequency operation of the electrical system is more stable, and the drive load capacity is stronger.

Excellent low frequency characteristics

Comprehensive protection, stable and reliable

The AC330 series special drives are equipped with all-around protection of software and hardware for synchronous reluctance motors. It has the functions of output-to-ground short-circuit protection, internal buffer relay protection, fan drive circuit protection, external 24VDC short-circuit protection, and motor overload protection. Realize the full protection of the motor and peripheral equipment.

Comprehensive protection, stable and reliable

Excellent stability under weak magnetic field

The AC330 dedicated drive is equipped with a unique field weakening control algorithm above the base speed to maximize the use of voltage limits. In this way, the output torque is maximized, the constant power range is expanded, and the stability of operation under a weak magnetic field is guaranteed.
