How to choose the model of Brushless DC motor
Generally according to the actual situation (load, structure size, etc.) to select the appropriate power, voltage, speed, torque and body size, and then according to the specific parameters of the selected brushless DC motor, to match the brushless driver.
What is the hall signal of brushless motor?
Hall signal usually refers to the rotor position signal of Brushless DC motor. Generally, there are two cases, high potential voltage and low potential voltage. Brushless DC motor uses rotor position signal (Hall signal) to control inverter commutation, which requires that Hall signal and stator three-phase winding have correct corresponding relationship.
Advantages of Brushless DC motor
Brushless DC motor not only maintains the good speed regulation performance of traditional DC motor, but also has the advantages of no sliding contact and commutation spark, high reliability, long service life and low noise, so it has been widely used in aerospace, CNC machine tools, robots, electric vehicles, computer peripherals and household appliances.
How to select the matching drive?
The selection of Brushless DC motor products should choose the appropriate working voltage, according to the customer must choose the rated value of the working voltage to select the main parameters of the controller working voltage, pay attention to the application of the working voltage in the full load and full load in the whole process does not need to exceed the scope of the controller requirements. Provide 24 V / 36 V / 48 V / 220 V series of Brushless DC products: 42 / 57 / 60 / 80 series refers to the motor flange size!
Specific application scope of brushless motor
Brushless motor is usually used in the equipment with high control requirements and high speed, such as model aircraft, precision instruments and so on, which strictly control the motor speed and achieve high speed. Usually, the service life is in the order of tens of thousands of hours, but due to different bearings, the service life of brushless motor is also very different.
