Brushless dc gear motor controller is a kind of high performance motor. The biggest characteristic of it is has the outer characteristic of dc motor without mechanical contact structure composed of brush. In addition, it USES permanent magnet rotor, no excitation loss: fever and installed on the outside of the stator, armature winding heat easily. Therefore, no commutation spark, brushless dc gear motor controller without radio interference, long service life, reliable operation, easy maintenance. In addition, its speed is not affected by the limitation of mechanical commutation, if use air bearing or magnetic levitation bearing, can run at up to hundreds of thousands of revolutions per minute. Compared to the control system of brushless dc gear motor has higher energy density and higher efficiency, and has a good application prospect in electric cars. Brushless dc gear motor controller has rapid response, large starting torque, rotating speed of from zero to rated speed can provide the rated torque performance, but the advantages of dc motor controller is also its drawback, because the dc motor controller to produce a constant torque under the rated load performance, the armature magnetic field maintain 90 ° with the rotor magnetic field to be constant, this is about to borrow from the carbon brush and commutator. Brushless dc gear motor controller is mainly composed of ontology, the position sensor of the motor and electronic switch circuit of three parts. The advantage of the brushless dc gear motor controller: 1, mature technology, stable performance; 2, can save the customer enterprise development, the product cost; 3, matching high, suitable for a variety of fields. Brushless dc gear motor controller is widely used in household appliances, auto parts, medical equipment, office automation, business equipment, industrial equipment, personal care, electric tools, and many other industries.
