Customized Electric Knife Motor, according to its use environment and use frequency of different forms are different. The characteristics of different forms of motor are different. At present, permanent magnet DC motor is widely used. Electric knife motor according to the electrical form to be divided, can be divided into brush motor and brushless motor two categories; According to the mechanical structure of the motor assembly, it is generally divided into two categories: "toothed "(high motor speed, need to be reduced by gear) and" toothless "(motor torque output without any reduction).
Permanent magnet DC motor: composed of stator pole, rotor, brush, shell, etc. Stator magnetic pole is made of permanent magnet (permanent magnetic steel), ferrite, al - ni - co, Ndfeb and other materials. According to its structure, it can be divided into cylinder type and tile type. The rotor is generally made of silicon steel sheet laminated, enameled wire wound between the two slots of the rotor core (three slots are three windings), and the joints are welded on the metal sheet of the commutator. Brush is connected to the power supply and rotor winding conductive parts, with conductive and wear-resistant two properties. Permanent magnet motor brush using a single metal or metal graphite brush, electrochemical graphite brush.
