Broadly defined permanent magnet drive technology
Thread Content
The broad concept of permanent magnet drive technology involves the creative use of an air gap to replace the mechanical connection between the prime mover and the equipment. The application of this innovative technology enables the transfer of energy through the air, achieving absolute sealing ； It can **reduce the energy consumption of the motor and the vibration in the transmission system** ； It changes the traditional concept of gear shifting, achieving high transmission ratios for reduction, acceleration, and differential action in a contactless manner. It represents the future path for the development of existing rigid or flexible connections. Broadly speaking, permanent magnet drive encompasses three technologies: 1. Permanent magnet couplings: they ensure synchronization between the driving and driven shafts, with a transmission ratio of 1; they solve sealing issues and achieve zero leakage. 2. Permanent magnet transmission: speed reduction, speed increase, differential drive ； High gear ratio, small size, high torque density. 3. Permanent magnet speed regulator: The drive shaft and driven shaft operate asynchronously; the output speed is adjusted according to the load level, enabling soft start, overload protection, and energy-saving speed control.
2. Permanent magnet transmission is also known as permanent magnet gear
Users of permanent magnet eddy current speed regulators share their experiences
The earliest ones I saw were installed in 2008 and 2010, and they are all still in normal use. I’ve also seen cases where it wasn’t used properly; users switched to other options and stopped using it. In any case, the quality of such products in China is currently inconsistent.
Will things get a bit better in a few years? There are quite a few of them in the country now; it’s a bit chaotic.
Permanent magnets~~ Those fake CD-related tech bonuses are definitely the best choice; however, one should still think carefully before using them. They’re everywhere, ‘blooming’ everywhere, boom~~~
