DC fan test polling station manufacturer of DC motor running-aging Taiwan manufacturers Rainbow please consult DC fan polling station manufacturers test run-aging DC DC fan test station manufacturers Rainbow patrol Taiwan manufacturer of DC motor running-aging Taiwanese manufacturers currently Rainbow DC fan more use of brushless DC motors, brushless DC motor By eliminating the excitation of the collector ring and brush, the structure is greatly simplified. At the same time, not only to improve the manufacturability of the motor, and the mechanical reliability of the motor running greatly enhanced, increasing life expectancy. Meanwhile flux density can be greatly improved, the motor indicator for optimal design, the direct effect is to reduce motor size, weight. Moreover, compared with other motor, also has a very excellent control performance. This is because: First, because of the torque constant, high-performance permanent magnet material leaving the motor torque inertia ratio, power density is greatly improved. By rational design but also make the moment of inertia, electrical and mechanical time constants and other indicators is greatly reduced, as the main indicator of servo control performance has been greatly improved. Second, modern permanent magnet magnetic circuit design has been more perfect, with coercivity permanent magnetic material, hence its ability to resist demagnetization resistance armature reaction and permanent magnet motors greatly enhanced motor control parameters with external Disturbance greatly reduced. Third, due to the use of permanent magnets to replace the electric field, reducing the field winding and the exciting field of design, thus reducing the magnetic field flux field winding inductance, the excitation current, and many other parameters, thereby directly reducing the controllable variables or parameters. Taking all these factors can be said permanent magnet motor with excellent controllability. At present, a large amount of wind capacity fan regulator has a lot of frequency control mode, this type of inverter mainly dependent on imports, the price is expensive. 1kw power levels below current fans, especially fans of household air conditioners and other existing permanent magnet brushless DC motor drives, and the use of wind speed transfer mode. 1 ~ 10kw huge amount of fan power range, the basic use of the induction motor, and the use of adjustable outlet opening of the way to adjust the amount of wind. For fans in this power range, the use of permanent magnet brushless DC motor drive to replace the original induction motor drive has a huge advantage. The method uses a distributed architecture microcomputer acquisition, each board consists of a single-chip computer and the corresponding measurement channels, individually DX series DC stabilized power supply, DX series DC stabilized power supply price, DX series DC steady Pressure steady power supply manufacturers, DX analog cell characteristics power supply manufacturers, DX analog battery power characteristics prices Shanghai JJW clean power exchange prices, JJW exchange purification power supply manufacturer, Yangzhou AC power supply manufacturer, AC power supply production factory , DX magnetic pole pairs detector price, DX magnetic pole pairs detector manufacturers, DX magnetic pole pairs detector manufacturers, electrical test equipment manufacturers, electrical test equipment manufacturers, electrical test equipment manufacturers prices, Yangzhou DX series DC electronic load, Yangzhou DX-8 AC electronic load box, DX Series DC Electronic Load manufacturers, automobile generator tester manufacturers, automobile generator tester price, magnetic switch tester manufacturers to complete a test various parameters of the motor measurement and monitoring, and upload the data to the host computer. Each board run separately, there is no direct contact with each other, each consisting of four boards a logging devices. Computer receives data analysis and processing, unusual circumstances, individual control of each motor is running. Simultaneous pressure on the four test motor voltage, current, speed, pump motor, 2-way brush temperature data acquisition, and upload to PC via RS232 interface, the timing of the measurement and monitoring. PC software using WindowsXP operating platform, using Vc compiled to complete the testing data graphics, table generation printing, and parameter settings.
