An electric motor is a machine that converts electrical energy into mechanical energy. Powering the motor with a battery or power supply will cause the shaft to start rotating. Some motors are powered by a DC power source (such as a battery), and some motors are powered by an AC power source. Although the motor has multiple design methods, the principle is the same.
There are two physical principles that lay the foundation for the operation of the motor. The first principle is the law of electromagnetic induction, which was discovered in 1831 by British scientist and inventor Michael Faraday. The content is that if the conductor passes through the magnetic field, or changes the strength of the magnetic field through the stationary conductive closed loop, an induced current will be generated in the conductor. The second principle, in contrast, refers to the electromagnetic reaction, which was observed by the French physicist Andel Maria Ampe in 1820.
Therefore, if a charged conductor (such as a length of copper wire) is placed in a magnetic field, it will be subjected to a force. The conductor is wound a number of turns, each turn is properly positioned and a current is passed through the conductor, and the force generated will Rotate the coil. When the coil rotates, the shaft of the motor will also rotate with it.
The motor consists of two basic units: a magnetic field, the electromagnet wound around the coil, and an armature, which is the mechanism that supports the cutting of the magnetic field and the conductor that delivers the excitation current within the motor.
Generators, which are the opposite of electric motors, convert kinetic energy into electrical energy.
Winding the motor is technical. First of all, we must know the number of stages, the number of turns, the wire diameter, and the data of the insulation motor, the line, the lower line, and the paint motor (phase number, number of stages, number of turns, wire diameter, Number of slots, winding form, coil span, stator core length, inner diameter, outer diameter)
According to the number of slots, the number of stages, to determine the number of coils of a set of coils, the number of turns determines the number of turns per coil, the inner diameter of the core and the outer diameter of the core to determine the circumference of the coil
According to the winding form (concentric, cross, etc.) inlay: (prepare the appropriate insulating paper before setting)
Inlaid wiring according to the span of the coil:
The number of parallel circuits of the motor series and the number of phases determine the baking varnish: (Before the baking varnish, the phase insulation is applied first, and the two ends of the stator are bundled with white cloth)
1. Record the relevant data of the original motor: stator core length, number of slots, number of poles, power, span, winding form, number of parallel paths, wire diameter, number of turns, wiring method, etc.;
2. According to the original coil measurement or calculation of the wire die size, make a selection of the line mode, and then follow the original coil data winding (wire diameter, number of turns, number of roots).
