Ultra-low speed permanent magnet direct drive motor

The remanufacturing of old motors with permanent magnets recycles and remanufactures the discarded motors that enterprises and the country are about to eliminate. The performance of our remanufactured products reaches the national level 1 energy efficiency, and the power saving rate reaches 10%-30%.

According to the statistics of the Ministry of Industry and Information Technology in 2015, the stock of inefficient motors in China is 2.4 billion kilowatts. Since 2012, the country has invested more than 4 billion yuan for renovation, but the renovation rate has still not exceeded 5%, that is, only 8% of high-efficiency motors are running on the front line of factories. If this technology can form a renovation capacity of 50 million kilowatts per year, it will take 48 years to complete the renovation. In response to such a huge market, we have also proposed a solution, which is the remanufacturing of old motors with permanent magnets. In simple terms, after an old motor arrives at our factory, we reuse important parts such as the shell and ingot, and at the same time replace all the components that affect the life, such as bearings, ingot sets, and windings. More importantly, we add our patented technology to the rotor, so that an old motor that is about to be eliminated by the country becomes a permanent magnet energy-saving motor.

The basic principle is simply to implant permanent magnets into the rotor to completely eliminate the excitation current and eliminate rotor losses. When the three-phase stator windings of the motor are connected to three-phase alternating current, a synchronous rotating magnetic field will be generated. This magnetic field interacts with the rotor permanent magnet magnetic field to drive the motor to rotate and convert energy, reducing the loss during motor operation. At the same time, the rotor does not generate iron loss and eddy current loss, reducing the motor's own loss. The high power factor reduces the stator current, and the stator winding resistance loss is reduced, thereby achieving the purpose of improving efficiency and saving energy and reducing consumption. Considering the large load fluctuation, these motors must be designed with higher power at the beginning of the design to prevent the load fluctuation from not operating normally. These industrial motors generally operate at 60%-80% of the operating load. From the figure above, it can be seen that the basic efficiency of our permanent magnet motor is still higher than 94%, and the power factor is higher than 0.95%, while the efficiency of the asynchronous motor is lower than 70%, and the power factor is lower than 0.7%. This is the characteristic of the permanent magnet motor.
