What are the advantages of a DC motor and an AC motor?
An AC motor is a machine used to convert mechanical energy and alternating current energy. AC motor has become the most common motor because of the great development of AC power system. Compared with the direct current motor, the AC motor has no commutator, so the structure is simple, the manufacture is convenient, the utility model is firm, and the motor with high rotating speed, high voltage, large current and large capacity is easy to be made. AC motors have a large range of power. AC motors are usually divided into AC generators, AC motors and synchronous regulators according to their functions. The precision spindle n AC reversible Henglin motor working state, the same motor can be used as a generator and motor. It is not very precise to divide the motor into generator and motor, but some motors are mainly used as generator, some motors are mainly motor operated.
The DC motor consists of two parts, stator and rotor, in which there is a certain air gap. The main feature of the structure is that it has an armature with a commutator. The stator of a direct current motor consists of a machine base, a main magnetic pole, a reversing magnetic pole, a front and back end cover, and a brush rack. The main magnetic pole is the main component of the air gap magnetic field of the DC motor. It is composed of a permanent magnet or a laminated core with a DC exciting winding. The rotor of the DC motor armature, the commutator (also called commutator) and shaft components. The armature is composed of two parts: armature core and armature winding. The armature core is made up of silicon steel sheets, and the slots are evenly distributed at its outer circle, and the armature windings are embedded in these slots. A commutator is a mechanical rectifier. The sheet is made of a metal clip or plastic to form a whole after it is folded into a cylindrical shape. Each commutator piece is insulated from each other. The quality of commutator has a great influence on the operation reliability.
Direct current motor (D.C.machine) is a kind of motor that realizes the conversion between DC energy and mechanical energy. When it is used as an electric motor, it is a DC motor. It converts the electric energy into mechanical energy. When the generator is running, it is a DC generator and converts mechanical energy into electrical energy.
