Wholesale sales dc motor series, micro motor also known as "motor", motor according to the law of electromagnetic induction to achieve the conversion of electrical energy or transfer of an electromagnetic device.The letter "M" is used in circuits.The function of micro motor is to generate driving torque as the power source of various electronic products.Dc motor is usually used more micro motor, the daily life of the electric toys, razors and other products are used to useful.Micro DC motor has two pins, connected to the positive and negative poles can turn, positive and negative can reverse.Dc motor speed is fast, but the torque is small.Suitable for all kinds of products requiring high speed, such as four-wheel-drive vehicles.
There are three different excitation modes for micro DC motors: permanent magnet, separate and self-excited (shunt, series and compound).
Supply power to the armature winding dc power through the brush, the surface of the armature current through the same direction under the N pole conductor can, based on the left hand rule conductor will be counterclockwise torque, the armature surface under the S pole current through the same part of the conductor is, according to the same left hand rule conductor will be counterclockwise torque.The entire armature winding will rotate counterclockwise, and the input dc electrical energy will be converted into the mechanical energy output by the rotor shaft.The miniature motor is composed of a stator and a rotor. The stator is composed of a base, a main magnetic pole, a commutator pole and a brush.Rotor: Armature core, armature winding, commutator, shaft.
