There is a certain relationship between the size of the motor magnet and the motor power, especially in the design of permanent magnet synchronous motor (PMSM) and brushless DC motor (BLDC), the size, shape and magnetic properties of the magnet directly affect the motor output power, efficiency and volume. Specifically, the relationship between the size […]

Multi-pole magnetic rings are called “natural Halbach arrays” because they are very similar in design and function to the principles of the Halbach Array. Here are the specific reasons: 1. The principles of magnetic field enhancement and weakening are the same The Halbach Array is a specially arranged magnet array, which is characterized by enhancing […]

How many magnets, or how many kilograms of magnets, are needed in an electric car?

The number of magnets or the total weight of magnets required for an electric vehicle depends largely on the type of motor, the size and design of the motor, and the power output required. The total weight of magnets required for a permanent magnet synchronous motor is very large, much larger than the total weight […]

SMT (Surface Mounted Technology) is the most popular process in the current electronic assembly industry. It is used to install pinless or short-lead surface mount components (SMC/SMD, chip components) on the surface of printed circuit boards or other substrates, and solder and assemble them through reflow soldering or dip soldering. SMT has the characteristics of […]
