Technological advantages of ompress`s
永磁变频控制技术优势
专利设计的弱磁控制，压力控制以及简单的永磁电机开环控制，适应多种恶劣工矿，系统更加稳定。
control of PM synchronous motors can adapt to various inclement conditi*** and the system is more stable
The rotor angular position sensor is not needed ,which not only simplifies the system,
at any angle within 360 degrees to achieve a perfect torque control. the utilization rate of
采用***的PID控制算法，加快了控制速度，提高了控制精度，为客户提供更稳定的供气压力。
C***tant power control technology makes the best the of the motor power When the setting pressure is lower than the highest pressure it fastens the motor speed to gain more air flow rate
