A water-cooled motor is a type of motor that uses a water-cooled system for heat dissipation. Compared with traditional air-cooled motors, water-cooled motors effectively reduce the temperature of the motor through a water cooling system, providing higher power density and better heat dissipation effect.

Water cooled motors have received increasing attention and application in recent years. As an efficient, energy-saving, and low-noise product, they have been widely used in many fields. So, what exactly is a water-cooled motor?

There are many types of magnets, including permanent magnets and soft magnets. Permanent magnets are further classified into two categories: metal alloy magnets, including neodymium iron boron magnets, samarium cobalt magnets, and aluminum nickel cobalt magnets. The second major category is ferrite permanent magnet materials. 1. Ferrite magnets: The main raw materials for ferrite include BaFe12O19 and SrFe12O19. Made by ceramic technology, it has a relatively hard texture and belongs to brittle materials. Due to its good temperature resistance, low price, and moderate performance, ferrite magnets have become the most widely used materials

On June 29th, in the security checkpoint of Baiyun Airport, security personnel found several magnets in the bag of a middle-aged male passenger heading to Nanjing. According to relevant regulations, the passenger had to give up carrying these magnets on board. On June 29th, in the airport security checkpoint, an X-ray operator discovered a high-density metal block in a passenger's bag and instructed the operator to conduct an open package inspection on the item. When the unpacker opened the bag, he found that these metal objects had firmly attached the keys, coins, and other items next to them. It turns out to be a few magnets! However, according to the Civil Aviation Safety Inspection Regulations, it may interfere with the normal operation of various instruments on the aircraft

In the 1840s, British physicist James Joule discovered that iron-based magnetic materials would change their shape but maintain their volume when placed in a magnetic field. This phenomenon is called "Joule magnetostriction", and in the 175 years since its discovery, all magnets have exhibited this characteristic. According to Science and Technology Daily, researchers from Temple University and the University of Maryland in the United States have discovered a new type of magnet. They heated a specific iron-based alloy in a furnace to approximately 760 degrees Celsius for 30 minutes, then rapidly cooled it to room temperature. When the material was placed in a magnetic field, it exhibited

Researchers from Temple University and the University of Maryland in the United States have discovered a new type of magnet that expands in volume when placed in a magnetic field, and wastes negligible amounts of heat during energy harvesting. This new discovery has enormous potential for application, not only to replace existing technologies, but also to create new applications. Hashe Dipp Chopra, the head of the Department of Mechanical Engineering and the Laboratory of Materials Genomics and Quantum Devices at Temple University, and Manfred Utig, a professor in the Department of Materials Science and Engineering at the University of Maryland, published their research results in the journal Nature on the 21st. Chopra said, "I
