How Motor Magnets Are Used in Electric Vehicles

Motor magnets are a fundamental part of electric vehicles. They provide the energy necessary for the vehicle's powertrain and can reduce the overall energy consumption. The most common type of motor magnet is the neodymium type. This material has a high magnetic strength and is characterized by a high intrinsic coercivity. However, the neodymium motor is susceptible to corrosion, which may lead to crumbling. To prevent this, the neodymium magnet has a protective coating to reduce exposure to the environment. Nickel plating is a standard method for this purpose. Polymer and lacquer protective coatings are also available. Samarium cobalt motor magnets are ideal for high temperature applications. They have outstanding temperature resistance, magnetic strength, and reliability even without oxidation protection.

For high-performance motors, permanent magnets should be made of strong materials. Neodymium and samarium magnets are strong, but they are not required to provide useful mechanical energy. The stronger the magnet, the greater the energy it can produce. In contrast, weak permanent magnets are suitable for producing electrical energy. Despite their low strength, permanent magnets exhibit high coercivity and a high magnetic moment. The coercivity of permanent magnets is much higher than that of ordinary magnets. As long as the temperatures are kept below the Curie point, permanent magnets will be stable even under extreme operating conditions.

The slew of new motor technologies has created a large number of opportunities for companies in the automotive industry. As a result, manufacturers are looking for ways to reduce the cost of production while maximizing performance. In some cases, it's possible to reduce the cost of manufacturing by reducing the production time. For example, manufacturers can avoid paying for the same parts twice, allowing them to create a more efficient product. These benefits, combined with lower capital costs, can make your car or truck more affordable than ever.

Since magnets cannot be removed from their starting positions, they must return to the same locations to repeat the attraction or repulsion process. Because of this, magnets have to travel short distances to remain within their starting fields and avoid repulsion. This results in loss of magnetic flux. Therefore, the next step in the manufacturing process is to choose a material that will not be damaged by heat. This type of metal will not have any effect on the magnets themselves, but rather on the surface of the motor.

Motors that use permanent magnets will be protected by a heat-shrinkable polyester tube. The tube is a special tube that allows the motor's permanent magnets to be fitted on a rotor. Once the tubes are fitted onto the rotor, they are instantly heat-shrunk to provide the magnets with protection and maximum magnetic flux. Unlike a dimmer switch, the new technology makes the neodymium motors easier to handle.
