Catalog of permanent magnet brushless DC motor control technology and applications

A brushless DC permanent magnet motor is usually made up of the following components: Permanent magnet: A permanent magnet is one of the most important parts of an electric motor, which generates a magnetic field that enables the motor to work.

Commonly used permanent magnets include permanent magnets, NdFeB and cobalt-iron. Stator: The stator is another important part of the arrester in electrostatic dust, which is usually composed of a coil and an iron core wound by copper wire.

The magnetic field of the stator's coil and the permanent magnet interact to enable the motor to rotate. Rotor: The rotor is another critical part in an electric motor, and it usually consists of magnets, cores, and bearings.

When an electric current passes through the rotor, it creates a magnetic field that interacts with the magnetic field of the stator and causes the motor to rotate. Sensors: Sensors are often used to detect the position and speed of an electric motor so that the motor controller can control the operation of the motor.

Controller: The controller is the brain of the motor, which usually consists of a microprocessor and a circuit board that controls the speed and direction of the motor. In general, the composition of brushless DC permanent magnet motors is relatively complex, and their operation requires the cooperation of multiple components and systems to achieve high-efficiency energy conversion and work.

Dear, the following are related extensions, I hope it will be helpful to you <><

In addition to the common three-phase brushless motor controllers, there are some other types of controllers that can be used for DC permanent magnet brushless motors. Here are some common extension options:1

Single-phase brushless motor controller: suitable for single-phase DC permanent magnet brushless source this hail control machine, often used in some low-power applications, such as household appliances, small electric vehicles, etc. 2.

Brushless motor drive: This type of controller is usually a device with integrated motor drive and control functions that can be connected directly to the power supply and motor, simplifying the cabling and installation of the system. 3.

Brushless motor controller module: This controller is usually an independent module, which can communicate with the main controller through serial port or other communication interfaces to realize the control and monitoring of the motor. 4.

Programmable logic controller (PLC) :p LC can be used for more complex control needs, and can be programmed to implement various control logic travel and functions, suitable for industrial automation and machinery control and other fields.

The basic parameters are: rated voltage, rated power, rated torque, load current, load speed, no-load current, no-load speed, maximum working point efficiency and power under rated load, damping coefficient, viscous damping coefficient, power factor, back electromotive force coefficient, structural parameters and including, stator slots, silicon steel sheet thickness, winding mode and so on.

The permanent magnet brushless motor can be regarded as a DC motor that replaces mechanical commutation with an electronic phase-returning device, and the structure of the permanent magnet permanent magnet brushless DC motor is mainly composed of the permanent magnet motor body, the rotor position sensor and the electronic commutation circuit. Whether it is the structure or the control method, the permanent magnet brushless DC motor has many similarities with the traditional DC motor: the stator pole of the brushed DC motor is replaced by a rotor equipped with a permanent magnet; replacing the armature with a stator with multiphase windings; Replace mechanical commutators and brushes with electronic commutators consisting of solid-state inverters and shaft position detectors.

The basic parameters I learned are: rated voltage, rated power, rated torque, load current, load speed, no-load current, no-load speed, maximum working point efficiency and power under rated load, damping coefficient, viscous damping coefficient, power factor, back electromotive force coefficient, structural parameters and including, stator slots, silicon steel sheet thickness, winding method, and so on!

It doesn't have to be too complicated, as long as you know the rated power, the rated voltage, the rated speed, the rated speed and size, you will know whether it is suitable or not.
