[0002] The motor refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction; the motor is represented by the letter M (the old standard is D) in the circuit, and its main function is to generate driving torque, as an electrical appliance or various The mechanical power source, the generator is represented by the letter G in the circuit, its main function is to convert mechanical energy into electrical energy, and the motor is divided into DC motor and AC motor, and DC motor has fast response, large starting torque, It has the ability to provide rated torque from zero speed to rated speed, but the advantages of DC motors are also its disadvantages, because the DC motor must produce constant torque performance under rated load, the armature magnetic field and the rotor magnetic field must be constant Maintain 90°, which requires carbon brushes and commutators; carbon brushes and commutators will generate sparks and carbon powder when the motor rotates, so in addition to causing damage to components, the use of occasions is also limited; AC motors do not have carbon brushes And commutator, maintenance-free, sturdy, wide application, but in terms of characteristics, if the performance equivalent to DC motor is to be achieved, complex control technology must be used; the rapid development of semiconductors nowadays, the switching frequency of power components is much faster, and the performance of the drive motor is improved; The speed of the processor is also getting faster and faster, which can realize the control of the AC motor in a rotating two-axis orthogonal coordinate system, and properly control the current components of the AC motor on the two axes to achieve similar DC motor control and performance equivalent to that of the DC motor. , but the existing motors generally do not have a cooling device, so that when the motor is working, there will be a lot of heat that cannot be dissipated in time. Due to excessive heat accumulation, it may affect the internal structure of the motor and reduce the service life of internal parts , It is not conducive to the use of the motor, and it is generally fixed by bolts during installation, which leads to very troublesome installation and disassembly process, inconvenient maintenance, and greatly reduces maintenance efficiency, which increases the workload of the staff and reduces the workload. efficiency
