The DC motor is to realize the conversion of DC electrical energy and mechanical energy of each other. When the motor is running, it can be converted into mechanical energy. The DC motor is composed of a stator and a rotor, with a certain air gap. The main feature of the structure is the armature of the commutator. The stator of a DC motor consists of a base, a main magnetic pole, a commutating pole, a front and rear cover, and a brush holder.
The main magnetic pole is the main component of the air-gap magnetic field of a DC motor. It is composed of a magnet or a laminated core with a DC excitation winding. The armature rotor, commutator (also called commutator) and shaft assembly of a DC motor. The armature consists of two parts: the armature core and the armature winding. The armature core is composed of silicon steel laminations, and the armature windings with uniformly distributed slots on the outer circle are embedded in the slots. The commutator is a mechanical rectifier. The back sheet is folded into a cylindrical shape, and a metal clip or plastic is formed into a whole. The commutator segments are insulated from each other. The quality and reliability on the commutator have a great impact.
AC motor is used to realize the conversion of mechanical energy and AC machine.
Due to the great development of AC power systems, AC motors have become the most commonly used motors. Compared with AC motors and DC motors, because there is no commutator, it has a simple structure, convenient manufacturing, and is relatively strong. It is easy to make high-speed motors, high voltages, large currents, and large capacity. The power coverage of AC motors is very large. According to their functions, AC motors are generally classified into alternators, AC motors, and synchronous cameras. The working state of the precision spindle AC reversible horizontal forest motor can also use the motor as a generator and motor.
