If say that the battery system is the blood of electric vehicles, electric control system is the brain of the electric car, then the motor system is the electric car muscle. For electric vehicles, the drive motor is essential. Taking new energy passenger cars as an example, we can see from the trend analysis of China's new-energy passenger cars from January to May 2017 that there is a very large demand for drive motors in China.
According to the National Federation of data, 2017 January-May total sales of new energy passenger cars 116 600. Among them, in January sales of 5400, February sales of 16,500, March sales of 27,500, April sales of 29,200, in May sales of 38000.
Observing Figure 1, we can see that the Ministry of Industry and Information Technology has raised the subsidy threshold of new energy vehicles: raising the threshold of the vehicle's driving range; introducing the new national standard of the power battery to improve the requirements on the safety, cycle life, charge and discharge performance of the battery; Battery energy density threshold, resulting in the development of new energy vehicles in January the market downturn.
In China, the development of new energy vehicles still has great potential, as its "muscle" drive motor development even more should not be underestimated. As China's demand for new energy vehicles to enhance the demand for its supporting motor is also getting higher and higher. The drive motor system is a new energy car one of the three core components.
Motor drive control system is the main executive structure of the new energy vehicles, the driving characteristics of which determine the main performance indicators of car driving, which is an important part of electric vehicles.
The entire electric vehicle drive system includes a motor drive system and its mechanical transmission mechanism of two parts. Motor drive system mainly by the motor, power converter, controller, a variety of test sensors and power supply and other components.
Motor in a variety of industrial products are more important as a component, as a variety of electrical and mechanical power source, the importance of the motor can be imagined. But if we want the motor to work better for us when it is in operation, the balancing of the motor is a problem that must be paid attention to.
New energy motor balancing machines, motor industry efficient balance assistant
In order to better help new energy motor manufacturers to improve work efficiency and reduce human error, Jian Ping dynamic balancing machine
after the design, in the balancing machine to increase the two-head power to the device, with the pneumatic clamping work function , Allowing the workpiece to be removed directly on the machine without disassembly, thereby increasing work efficiency.
This balancing machine with a professional design of the swing frame, which can effectively transfer mechanical force, good rigidity to ensure that the vibration damping machine is relatively small; high sensitivity sensors and permanent calibration of the measurement principle, to achieve a high accuracy. In addition, in order to make the operator more comfortable operation time, the use of advanced electrical measurement system to make the human-computer interface more friendly, while the design also refers to the ergonomics, make every effort to ensure that the comfort of staff operating degree.
Suitable for new energy vehicles are mainly permanent magnet synchronous motor drive, AC asynchronous and magnetoresistive switch three categories. Because of their different characteristics, each has its own application. At present, the new energy vehicle drive motor industry attractive, potential market space, the industry standard is not yet determined, the vehicle supply chain immature, with the new energy vehicles to grow together, it is the ideal sunrise industry.
