The brushless motor is a motor based on electronic commutation technology. Compared with our traditional DC motor, its life and efficiency are improved. At present, brushless motors are also used in more and more fields according to their characteristics. In the introduction of this article, the basic principle, structure, characteristics and application of the Nema 45 brushless motor will be highlighted.
With the continuous development of the current technological era, brushless motors play an extremely important role in various fields, and their application fields are becoming more and more extensive. The brushless motor is a motor based on electronic commutation technology, which is improved on the basis of the traditional DC motor. Compared with traditional DC motors, brushless motors have higher efficiency and longer life, so they have also been used in industrial and agricultural industries. Brushless motors have become an integral part of modern technology.
Electronic commutation technology to realize the steering of the motor is the basic principle of the brushless motor. Brushless motors are usually also composed of rotors, stators, sensors and electronic commutators. As the name suggests, the electronic commutator is to control the direction of rotation of the motor. Customization is to fix the motor. The sensor detects the position of the rotor according to the principle. The rotor is the rotating part of the brushless motor. Because the brushless motor uses electronic fantasy technology to realize the rotation of the motor, it will have higher efficiency and service life than the traditional DC motor using machinery to control the rotation of the motor.
Brushless motors usually consist of rotors, stators, sensors, and electronic commutators. Among them, the rotor is the rotating part of the motor, the stator is the fixed part of the motor, the sensor is used to detect the rotor position, and the electronic commutator is used to control the steering of the motor.
In a brushless motor, the rotor consists of permanent magnets and the stator has three sets of windings. Sensors usually use Hall elements to detect rotor position. The electronic commutator consists of transistors and capacitors, etc., and is used to control the direction and speed of the motor.
The nema 45 brushless motor has the following parameters, the size is 110x110mm, the voltage is 48V, 110V, etc. We can also accept customization, as long as you synchronize your specifications to us, we can give you a clear answer. The power can reach 1000W to 3000W, which is higher than the traditional DC motor, and the work is more stable. The rated speed is around 3000RPM. For the detailed parameters of the motor, you can contact us for more information.
The brushless motor removes the brush, and the direct change is that there is no electric spark generated when the brushed motor is running, which reduces the interference of electric sparks on remote control radio equipment.
There are no brushes in the brushless motor, the friction force is greatly reduced during operation, the operation is smooth, and the noise will be much lower. This advantage is a huge support for the stability of the model operation.
Without brushes, the wear in a brushless motor is primarily on the bearings. From a mechanical standpoint, it's pretty much a maintenance-free motor. Just do some dust removal maintenance if necessary. Brushless motors have low-speed torque performance and high torque. Features are irreplaceable for it, with the downward trend of the cost of brushless controllers and the development of brushless technology and market competition, brushless power systems are being developed and promoted at a high speed, which affects the development of model sports.
Brushless DC motors are used in a wide range of applications, such as automobiles, tools, industrial control, automation, and aerospace. In general, brushless DC motors can be divided into the following three main uses:
1. Sustained load applications: mainly in the fields that require a certain speed but not high requirements on speed accuracy, such as fans, water pumps, hair dryers, etc. These applications have low cost and are mostly open-loop control.
2. Variable load applications: mainly applications where the speed needs to change within a certain range, and have higher requirements for motor speed characteristics and dynamic response time characteristics. For example, dryers and compressors in household appliances are good examples. Oil pump control, electric controller, engine control, etc. in the automotive industry, the system cost of such applications is relatively higher.
3. Positioning application: Most industrial control and automatic control applications belong to this category. In such applications, energy transmission is often completed, so there are special requirements for the dynamic response of the speed and torque, and the requirements for the controller are also high. . Photoelectric and some synchronization equipment may be used for speed measurement. Process control, machinery control, and transportation control are many examples of such applications.
