In the operational symphony of industrial equipment, the motor undoubtedly serves as the core "performer," and the precision of its selection directly determines the harmony and stability of the equipment's operation. Recently, a minor episode occurred with our Chnchi Electric's permanent magnet synchronous motor in a customer's hydraulic freight elevator application. When the hydraulic elevator operated at high speed, the motor emitted noticeable noise, which immediately drew the customer's attention and inquiry. Chnchi Electric Nanjing Co., Ltd. responded swiftly, dispatching a team of professional engineers to investigate. After a thorough inspection, it was determined that the noise originated from the high-speed operation of the hydraulic pump under the new motor's rotational speed.

It turned out that the customer had previously used a three-phase asynchronous motor with a speed of 1400 RPM, while the newly selected Chnchi servo motor reached 1700 RPM. This change, while offering the potential for increased power, also introduced new challenges. 

However, this was precisely the moment to showcase Chnchi Electric's professional expertise. Our engineers, leveraging their profound technical knowledge and extensive experience, made precise adjustments by setting the motor frequency to 100 Hz, stabilizing the motor speed at 1500 RPM. This seemingly minor adjustment brought about a significant transformation—the hydraulic elevator's operation became quiet and smooth, perfectly meeting the customer's requirements. 

Behind this incident lies the critical importance of permanent magnet synchronous motor selection. The appropriate motor speed must complement other components of the equipment, such as the hydraulic pump, to achieve efficient, stable, and low-noise operation. Chnchi Electric not only focuses on delivering high-quality motor products but also backs them with a professional technical service team, ensuring that every customer receives prompt and effective solutions to any issues encountered during product use.
