Inverter industry status
We predict that the inverter industry will also usher in high-speed addition. According to estimates, the inverter market sales revenue plan will increase from $1.2 billion in 2015 to 13.3 billion in 2030.
From the sales point of view, because the share of inverters and motors is basically 1:1, it is estimated that the total sales will increase from 3.6 million in 2015 to 49 million in 2030.
At the same time, the price of bicycles will drop from $300-$400 to $200-$300, mainly due to the cost planning effect after the volume.
Similar to the motor category, the Toyota Group in the inverter industry is now also in the leading position. At the same time, Denso Group, a subsidiary of the Toyota Group, is now expanding its inverter customers. After Toyota, Mitsubishi Electric also has a considerable market share.
Technological evolution
From the classification of the motor, there are four kinds of DC, communication induction, permanent magnet synchronization and switching reluctance. The new energy car motor mainly uses the latter three.
Now, permanent magnet synchronization is the mainstream motor type because of its superior function. The price of communicating asynchronous motors is moderate, but the function is slightly worse. It is used by some manufacturers in the United States and China. The primary advantage of switched reluctance motors is their low price, but there are also technical problems with noise and sensation. If these problems can be solved, switched reluctance motors will have a large market.
Communicating asynchronous motors: Although from now on, communicating asynchronous motors has no advantage over permanent magnet synchronous power, its cost is much lower than that of permanent magnet synchronous motors. In terms of volume, communication asynchronous motors are larger than permanent magnet synchronous motors, and are primarily constrained by design and construction.
Permanent magnet synchronous motor: There is a rotor with a permanent magnet inside the motor. The whole system has high power and small volume. The cost is relatively expensive, mainly because of the high price of permanent magnet materials. Discussions on the use of falling permanent magnets are now under development, and research is also focused on improving the output efficiency of magnets. Permanent magnet motors were the most widely used types of motors in the electric motor industry at the time.
Switched Reluctance Motors: Switched Reluctance Motors are very competitively priced, primarily because there are no high-cost permanent magnets in their rotors, and their power is moderate. Because the tension of the stator and rotor is used to supply power, the sensation and noise caused by the process are its primary problems. Because the electric vehicle motor is now in a rapid period of time, we believe that the increase in demand will accelerate the replacement of technology.
