brushless dc motor controller to replace imports, have become the focus in the current drive with the motor controller. Trade war continued fermentation and expansion, manufacturing is the core of the U. S. export restrictions to China industry. , which is expected to benefit from the domestic point of view is subject to the restrictions on imports of relevant industry expected domestic shall give further policy support, China's trade on the offensive policy should be mainly concentrated in a large number of imported commodities related industries in the United States, expected industry due to the supply gap for domestic products further instead of imported goods. For example, using the domestic production of brushless dc motor controller to replace the imported motor controller. Here, we have to get to know some brands in our country independent research and development, production of brushless dc motor controller has the performance, advantages. Brushless motor controller is mainly composed of ontology, electronic motor commutator and rotor position sensor and other components. Controller of brushless dc motor armature winding on the stator, the rotor is made of permanent magnetic material permanent magnets. Permanent magnet brushless dc motor controller in electronic commutator replaces mechanical brush and commutator, eliminating the electrical sliding contact mechanism. Brushless motor controller without carbon brush structure of this novel, reducing the rotor's own mechanical energy loss and prolong the service life. Brushless dc motor controller has the following properties and advantages: 1, energy saving features: high efficiency of energy conversion, the maximum efficiency is in commonly 85%, some products can reach above 90%, 2 control features: rapid starting, braking and fast response, mechanical time constant is less than 50 milliseconds, some products can reach 30 milliseconds; In recommend running area of high-speed operation condition, can be easily to sensitive to adjust speed. 3, drag characteristics: running stability is very reliable, speed fluctuation is small, as its micro motor speed fluctuation can be easily controlled within 10%. In addition, compared with the same power of motor controller, its weight, reduce 1/3 - volume 1/2. Brand of brushless dc motor controller with high efficiency, easy to heat dissipation, high reliability, good dynamic performance and other characteristics, have become the focus in the current drive with the motor controller. To support the China trade defense policy, the construction of the masses of friends with domestic production of brushless motor controller.
