Bigfans Ventilation Equipment (Wuhan) Co.,ltd

PMSM (Permanent Magnet Technology and Innovation) PMSM stands for permanent magnet synchronous motor. PMSM Fengrui series is a new type of fan based on PMSM (permanent magnet synchronous motor) technology developed by Bergfeien Company, Huazhong University of Science and Technology and Wuhan Institute of Technology. The motors, produced in-house by Bergfairn, have a maximum diameter of 7.3 meters and a minimum diameter of 2.5 meters. The product combines the cutting-edge technology of a series of comprehensive disciplines such as aerodynamics, dynamics, pulse width modulation control technology, mechanical mechanics, simulation technology, communication control, industrial design, etc., and is manufactured by using domestic and foreign precision processing equipment and winding equipment. Each motor has undergone more than 10 professional equipment tests, including withstand voltage and temperature test, torque test, current and voltage inductance resistance, and induced electromotive force test! In terms of material selection, the service life of the motor is the highest standard! The service life of the motor is more than 10 years! Combined with the frequency conversion control system developed by Bergfain and Sinoking, it can promote the flow and circulation of space airflow with higher efficiency, achieve the purpose of personnel cooling, and improve the comfort of the environment! Bergfein has mastered the two core technologies of motor and control! Based on technical services and based on the market! At present, it has been exported to 18 countries around the world!
