DC brushless motor advantages 2024-07-23 16:25:49 internet

It is composed of DC brushless motor and driver. It is a typical electromechanical product.DC brush -free motor refers to a motor that is not brushed and the directioner (or electric ring), also known as a non -switching motor.As early as the Nineteenth Motor was born, the practical motor generated was a brushless form, that is, the mouse -cage asynchronous motor, which was widely used in this motor.However, asynchronous motors have many flaws that cannot be overcome to develop slowly.
DC brushless motor advantages
1. The permanent magnet of the DC brushless motor is now mostly used with high magnetic energy accumulated rare earth, iron boron boron material.Therefore, the volume of the rare earth permanent magnetic brush -free motor is compared to the same capacity three -phase asynchronous motor to reduce a seat number.2. The high efficiency of DC brushless motor, high efficiency area, high power and torque density, power factor (COSφ) is close to 1, system efficiency 90%, permanent magnetic brush -free DC motor rotation runs simultaneously in any case.AC variable frequency conversion motor is the frequency conversion speed regulation. The brushless DC motor is the speed regulating frequency conversion. The motor runs under synchronous speed. The rotor is neither copper and no iron consumption.3. DC brushless motor has the advantages of good low voltage characteristics, strong torque overload characteristics, large starting torque (blocking characteristics), and small starting current.4. DC brushless motor has the characteristics of a brush motor, and the driver is also a device that changes frequency.The inverter is better. Since the brushless DC motor is running in a self -controlled operation, it will not start the winding winding on the rotor like the starting motor that is launched under the speed adjustment of the variable frequency.Step.Over the years, the industrys research on asynchronous motor variable frequency speed adjustment is in the final analysis to find the way to control the torque of asynchronous motor.Small characteristics have appeared in the field of speed regulation.It can solve the needs of industrial nodes and high -performance drivers.

DC brushless motor principle
The DC brushless motor consists of the main body of the motor and the driver. The stator winding of the motor is mostly made into three -inquir star connection method. The same three -phase asynchronous motor is very similar.The motor rotor is adhered to a magnetic permanent magnet. In order to detect the polarity of the motor rotor, it is equipped with a position sensor in the motor.The driver consists of power electronic devices and integrated circuits. Its function is to accept the motors start, stop, braking signal to control the starting, stop and braking of the motor;The passing of the power tube of the bridge generates continuous torque; accepting speed instructions and speed feedback signals are used to control and adjust speed; provide protection and display, and so on.Because the DC brushless motor is running in a self -control type, it will not be launched on the rotor to the rotor on the rotor like a variable frequency speed adjustment.
