There are many classifications in the electrical industry: geared motors, motors, generators, motors, transmissions, gearboxes, etc. , and each geared motor, motor, and motor have many small categories, and each category has a different working principle of the geared motor. Now Leo durable gear motor briefly introduces the classification, structure and working principle of gear motor.
There are three types of geared motors: DC geared motors, synchronous geared motors, asynchronous geared motors, DC geared motors are rotating electrical machines that convert DC electrical energy into mechanical energy (DC motors) or convert mechanical energy into DC electrical energy (DC generators).
According to its use, it can be divided into motors and generators, but there are also other special-purpose motors, such as actuators in automatic control systems and torque motors for general transmission power. The DC motor is fixed with a ring permanent magnet, and the current is passed through the coils on the rotor to generate the Loren magnetic force. When the coils on the rotor are parallel to the magnetic field, the direction of the magnetic field that continues to rotate changes. Therefore, at this time, the brushes at the end of the rotor are in alternate contact with the conversion piece, which causes the direction of the current on the coil to change, and the direction of the generated Loren magnetic force does not change.
Therefore, with the wide application and perfection of the thyristor rectifier power supply, the geared motor can maintain the direction of rotation. DC generators still have a certain status in certain fields (such as vacuum smelting industry, no AC power grid, and occasions that require DC power). DC motor structure: main magnetic pole, commutation pole, seat, brush device, rotor, armature core, armature winding, commutator, shaft, DC motor excitation mode: DC motor excitation mode, DC motor, series excitation DC Motor, compound excitation DC motor geared motor.
