Excellent quality, outstanding drag
The key component of the elevator drive system—DongAo frequency conversion system is manufactured with cash military technology, and it has been in the international leading position in the world frequency conversion system manufacturing industry.
Due to the use of the most advanced insulated gate bipolar field effect power transistor IGBT, the inverter realizes the PWM control of the high frequency carrier, which significantly reduces the noise of the motor, and has low power consumption and long life. With digital speed setting S-curve acceleration/deceleration and torque offset function to compensate for load changes, it can provide high-precision control and high reliability in long-term operation and temperature fluctuations, especially in the control speed accuracy , Reaching ±0.01%, which is recognized as the highest current level in the industry in the world. Such an advanced driving system provides DongAo elevator with the best power, voltage and frequency, making the elevator run more sensitive, smooth and smooth, and bringing passengers a more stable, comfortable, warm, safe and reliable riding feeling.
Today, DongAo's comprehensive cooperation and joint venture will surely bring more high-quality elevator products and perfect sales services to users, and create a more perfect loading space for you.
