Now the best speed motor: The square-wave-controlled permanent magnet synchronous motor, in order to replace the carbon brush Hall sensor
Commutator, to NdFeB permanent magnet material as the rotor; product performance beyond the traditional all the advantages of DC motors with
Shiyou solve the carbon brush DC motor slip ring shortcomings, digital control.

Brushless DC motors with high efficiency, high torque, high precision characteristics of the three is very suitable for use within 24 hours of continuous operation of industrial machinery and air-conditioning refrigeration host, fan pumps, air compressor load; low-speed high torque and high-frequency degree of positive inversion is not hot feature is more suitable for machine tool machine tools and traction motor drives; its steady-speed running accuracy higher than the DC brush motor, compared with vector control or direct torque control of inverter-driven but also the speed closed-loop high, and better cost performance is the best choice for a modern governor-driven.
