Rotor commonly used silicon layers from motor uses fewer slots than the electromagnetic DC motor rotor. Small motors used in the majority of VCR 3 slot motor brands, more upscale 5 slot or 7 slot. Enameled wire around the rotor core between two slots (three slots that is three windings), which are each welded joints in the metal sheet commutator. Brushless DC motor is the use of semiconductor switching devices to achieve electronic commutation, which uses electronic switching devices replace the traditional contact commutator and brushes. It has high reliability, no commutation spark, and low mechanical noise, widely used in high-end tape deck, video recorders, electronic equipment and office automation equipment. _ _ Liter motor motor price by liter Rui Rui Electrical and Mechanical Ventilation and Air Conditioning Electrical Equipment Factory.
