Description

Technical Field

[0001] The utility model relates to the technical field of the shell of a silent variable-speed motor, in particular to a reinforced box high-strength silent variable-speed motor shell. Background Technique

[0002] A rotary machine that converts electrical energy into mechanical energy. It mainly includes an electromagnet winding or a distributed stator winding for generating a magnetic field and a rotating armature or rotor. There is current passing through its wires and it rotates under the action of the magnetic field. Some types of these machines can be used as motors or generators.

[0003] A motor is a device that converts electrical energy into mechanical energy. It is made using the phenomenon that a current-carrying coil rotates in a magnetic field. It is distributed at each user location. Motors are divided into DC motors and AC motors according to the different power supplies used. Most of the motors in the power system are AC motors, which can be synchronous motors or asynchronous motors (the rotational speed of the stator magnetic field of the motor does not maintain the synchronous speed with the rotational speed of the rotor). A motor mainly consists of a stator and a rotor. The direction of the force on a current-carrying wire moving in a magnetic field is related to the direction of the current and the direction of the magnetic induction line (magnetic field direction). The working principle of a motor is the force exerted by a magnetic field on a current, which causes the motor to rotate.

[0004] It is a machine that converts electrical energy into mechanical energy. Usually, the working part of the motor makes a rotational motion, and this kind of motor is called a rotor motor; there are also those that make a linear motion, called linear motors. The power range that a motor can provide is very large, from milliwatt level to ten thousand kilowatt level. The use and control of a motor are very convenient, with capabilities such as self-starting, accelerating, braking, reversing, and holding, and it can meet various operating requirements; the working efficiency of a motor is relatively high, and there is no smoke, smell, no environmental pollution, and the noise is also relatively small. Due to its series of advantages, it is widely used in various aspects such as industrial and agricultural production, transportation, national defense, commerce, household appliances, and medical electrical equipment.

[0005] The most widely used among various motors is the AC asynchronous motor (also known as an induction motor). It is convenient to use, runs reliably, has a low price, and has a firm structure, but its power factor is relatively low and speed regulation is also relatively difficult. Synchronous motors (see synchronous motors) are commonly used for large-capacity low-speed power machines. Synchronous motors not only have a high power factor, but also their rotational speed has nothing to do with the load size and only depends on the power grid frequency, and they work more stably. DC motors are mostly used in occasions where wide-range speed regulation is required, but they have a commutator, are structurally complex, expensive, difficult to maintain, and are not suitable for harsh environments.

[0006] After the 1970s, with the development of power electronics technology, the speed regulation technology of AC motors has gradually matured, and the equipment price has been decreasing day by day, and it has begun to be applied. The maximum output mechanical power that a motor can bear without causing the motor to overheat under the specified working system (continuous operation system, short-time operation system, intermittent periodic operation system) is called its rated power, and the regulations on the nameplate should be noted during use. When the motor is running, it is necessary to pay attention to matching the characteristics of its load with those of the motor to avoid runaway or stalling. There are many speed regulation methods for motors, which can meet the requirements of different production machinery speed changes. Generally, the output power of a motor will change with the speed. From the perspective of energy consumption, speed regulation can be roughly divided into two types: ① Keep the input power unchanged. By changing the energy consumption of the speed regulation device, the output power is adjusted to regulate the speed of the motor. ② Control the input power of the motor to regulate the speed of the motor.

[0007] However, many current variable-speed motors are prone to equipment instability and increased equipment noise after long-term use. Therefore, an improved technology is urgently needed to solve this problem existing in the prior art. Summary of the Invention
