Description

Brushless steam pump motor

Technical Field

Background

The history of brushless motor development can be traced to the end of the 19 th century. In 1905, the uk scientist John Berry doctor proposed a brushless motor concept that employs electronic commutation to control motor speed and direction. Although such motors have not found widespread use, they are an important milestone, promoting the development and improvement of brushless motor technology. With the continuous development and improvement of electronic technology, the technology of brushless motors is also continuously developed and perfected. In recent years, due to breakthrough of chip technology, people can control the rotating speed and the steering of the motor more accurately, so that various application requirements are better met. Although there are still challenges and problems to be solved, brushless motor technology has become an integral part of the biomedical, industrial, automotive manufacturing fields, etc.

Currently, motors are devices that convert electrical energy into mechanical energy in a magnetic field through which current flows, and can be classified according to various references, such as the type of power source, the position of the rotor and stator, and whether permanent magnets are used.

For example, the motors are classified into Direct Current (DC) motors and Alternating Current (AC) motors according to the type of power source, and the DC motors are classified into brush motors and brushless motors. In the DC motor, the brush-attached motor is used to allow current to flow to the coil and commutate the current through contact between the commutator and the brush, but has disadvantages of generating mechanical and electrical noise and wearing the brush. In order to overcome such a disadvantage, a brushless motor that does not use a brush is widely used. Brushless DC motors are motors that remove brushes and commutators from the DC motor and mount an electronic commutation mechanism, also known as non-commutated motors.

With the progress of technology, the higher the demands of people for life, the more the development of electrical appliances is affected, wherein the motor is the focus of development. In order to refine the motor, a number of motors with high performance and low consumption are developed in the market, wherein the brushless motor is widely applied to various electrical appliances because of the advantages of high efficiency and low noise, however, the current electrical appliances, both electric tools and home appliances, are developed towards miniaturization, so that the existing motors have the disadvantage of excessively large volume to hinder the development of technology.

The existing brushless motor comprises a stator group and a rotor group, taking a six-slot brushless motor as an example, the stator group comprises a stator core, the stator core is provided with six wire slots and three enameled wires, the enameled wires are respectively wound in the three wire slots from one end of the stator core, and then are wound to the other three wire slots on the opposite sides from the other end of the stator core, thereby forming six stator windings. A rotor of the rotor set penetrates through the stator core and is surrounded by the plurality of stator windings. The commutation signal is output to the plurality of stator windings so that the plurality of stator windings generate different magnetic field changes, and the rotor rotates under the action of the magnetic field, thereby achieving the purpose of rotating the brushless motor. There is a need for a brushless vapor pump motor.
