Neodymium magnet for stepping motor

This Neodymium Magnet for Stepping Motor has a classic round design with a center hole in the middle, which is both beautiful and practical. The magnet is silver or gray in color with a charming metallic luster, highlighting its high-quality characteristics. The surface of the magnet is finely polished to present a smooth and shiny appearance, which is not only pleasant to the touch, but also ensures its stability and durability in application.

The washer-style edge design, that is, the edge is slightly raised outward, not only increases the structural strength of the magnet, but also makes it more stable during installation and fixing, and not easy to fall off. This design not only improves the beauty of the product, but also makes significant progress in practicality and stability.

The center hole is designed to meet the specific needs of stepper motors during installation and use. It can not only be used for threading, hanging and other purposes, but also can be closely combined with other parts of the motor to achieve precise positioning and stable operation. This design makes the magnet play a vital role in stepper motors.

Accurate positioning: Due to the high performance and high-precision processing of the magnet, it can ensure the precise positioning and stable movement of the stepper motor during operation, improving the performance and reliability of the motor.

Easy to install: The size and shape of the magnet are designed reasonably, making it easier and faster to install in the stepper motor, reducing installation costs and time.
