The difference between brushless generator has a brush


Because brushless dc generator has the characteristics of a dc motor, is also the device of frequency variation, so also known as dc frequency conversion, the international general term for BLDC. MotorsBrushless dc motor operation efficiency and precision of low speed torque and rotational speed is more good than any of the control technology of inverter, so the industry concern.

Brushless motor in our country, the development of the time is short, but as the technology increasingly mature and perfect got rapid development.Has been used in model aircraft, medical equipment, household appliances, electric cars, and other fields is widely used, and in shenzhen, changsha, Shanghai and other places to form certain scale industrial chain.Such as shenzhen weiye motor, a batch of professional manufacturers, such as changsha keda constantly promoting industry development in technology.In recent years, the brushless motor become a rapid development in the field of model of a kind of power.Because of production and price, over the past few years brushless motor used in high-grade aviation model, now due to the rapid development of machining technology, the production cost of brushless motors dropped many, it is into the model in the field of all levels, from electric remote control cars to electric remote control boat to electric model planes, everywhere.


Rely on, in short, change the input to the brushless motor stator coil of alternating current wave frequency and waveform, the winding coil around a rotating magnetic field, electrical geometry axis on the magnetic field to drive the rotor permanent magnet steel, motor turned up and the performance of the motor and the number of magnetic steel, magnetic steel, magnetic flux intensity, and the size of the motor input voltage and other factors, more with brushless motor control performance has much to do, because the input is the direct current, current need electronic governor turned it into three phase alternating current (ac), also need to receive control signal from the remote control receiver, control motor speed, to meet the needs of the model using.In general, the structure of the brushless motor is relatively simple, really determine its performance or brushless electronic governor, good electronic governor needs a single chip microcomputer control program design, circuit design, control the overall process, such as complex processing technology, so the prices are much higher than a brush motor.


A brush motor faults

Friction, and wide consumption

With friends to play before the old die brush motor when they encounter this problem, that is to use the motor after a period of time, need to open the motor to clean up the carbon brush, time-consuming, laborious maintenance strength as a household cleaning.

Fever is big, life is short

Because have a brush motor structure, brush and commutator of the contact resistance is very big, a motor as a whole is bigger, resistance to heat, and permanent magnet is a thermal sensor, if temperature is too high, will be demagnetization magnetic steel, the motor performance degradation, affect the service life of a brush motor.

Efficiency is low, the output power is small

Said to have a brush motor heating problems above, largely because the current work on the internal resistance of the motor, so electricity have much transformed to heat energy, so there are motor output power is not big, the efficiency is not high also.

Brushless motor

No brush, low interference

In addition to the brushless motor brush, the most immediate change is without the motor running when the electric spark, thus greatly reduce the electric spark interference of remote radio equipment.

Low noise, smooth operation

Brushless motor without brush, less friction force during operation, smooth running, low noise will many of the advantages of model running stability is a huge support.

Long life, low maintenance cost

Wear little brush, brushless motor is mainly on the bearing, from the mechanical point of view, brushless motor is almost a maintenance-free motor, when necessary, the only need to do some cleaning maintenance.Next comparison, know brushless motor relative to have advantage in where the brush motor, but everything is not absolute, a brush motor torque at low speed performance, large torque and other performance characteristics is irreplaceable brushless motor, but in the context of use and ease of brushless motor, with the decline in the cost of brushless controller and brushless technology development and market competition both at home and abroad, brushless power system is the development and popularity of high-speed phase, which greatly promoted the development of the model of movement

Comprehensive comparison, know brushless motor relative to have advantage in where the brush motor, but everything is not absolute, a motor torque at low speed performance, large torque and other performance characteristics of brushless motor is irreplaceable, but in the context of use and ease of brushless motor, with the decline in the cost of brushless controller and brushless technology development and market competition both at home and abroad, the development and popularity of power system is high speed brushless stage, which greatly promoted the development of the domestic brushless motor.

Health cloud generator is the increase of the related services based on Internet, use and delivery mode, usually involves using the Internet to provide dynamic easy extension and often virtualized resources.A cloud is a network, a metaphor of the Internet.In the past often expressed in the cloud to telecommunication network in the picture, and then used to represent the Internet and the underlying infrastructure of the abstract.Health cloud refers to through the network to obtain the required in the form of on-demand, easy extension services.This service can be IT and software, the Internet, but also other services.It means also can be used as a kind of ability to calculate the flow of goods through the Internet.

The advantage of the cloud

The remote monitoring and control

 no matter anywhere in the world, as long as there is network, can use mobile phone or PC computer remote monitoring the operation of the generator set data, control the operation of generating set

In addition to basic information monitoring unit, but also can monitor the excitation voltage, electric adjustable output voltage, bearing temperature, winding temperature, etc.A more comprehensive monitoring for accurately check the health status of the unit

Mobile terminal remote monitoring

 USES the camera embedded technology, can clearly see the cloud generator in remote site environment, avoid accidental operation risk events.


Generator running state of real-time dynamic data display, clear understanding of the current generator running state

Each detail data real-time display engine, engine real-time running is normal

Real-time display various detailed data generator, to understand whether the parameters of the generator in the normal range

Improve reliability - health monitoring unit

Health check report every Monday

Through powerful intelligent data fetching patent technology, grab the motor starting before and after the battery voltage, no-load voltage and speed for 10 seconds, excitation voltage, the electric adjustable output voltage, bearing temperature, etc, the automatic analysis of the data and generate a health check report every week, realize the health examination and early failure prevention, allows users to make maintenance, according to health guarantee the stable operation of the unit, prolong the life of generator set.

Quickly solve the problem of fault - black patent technology

Unit fails, the manufacturer directly through the cloud server for 18 seconds of black, technical personnel to analyze data, remote fault diagnosis, reduced for fault situation of communication between manufacturers and users, quick analysis the cause of the problem, solve the problem
