Permanent Magnet Rotor Assembly

Tengye specializes in the manufacture of magnets and magnetic assemblies, offering cutting-edge solutions for a wide range of applications. Our permanent magnet rotor assembly, designed for use in brushless DC (BLDC) motors, generators, and more, are built with the highest quality materials, including neodymium magnets and multipole ring magnets. In this article, we will explore what makes our permanent magnet rotor assemblies stand out from the competition and why they are the ideal choice for your applications.

Understanding Permanent Magnet Rotor Assemblies

A permanent magnet rotor assembly is a crucial component in various applications, including BLDC motors, generators, and magnetic couplings. It consists of a rotor with permanent magnets, such as neodymium magnets, mounted on it to ensure an efficient and reliable magnetic field generation. The interaction between the magnetic field produced by the rotor and the stator (the stationary part of the motor or generator) enables the conversion of electrical energy into mechanical energy or vice versa.

Tengye’s permanent magnet rotor assembly, featuring neodymium magnets and multipole ring magnets, is the ideal choice for those seeking high-quality, reliable, and efficient magnetic solutions for their BLDC motors and other applications. Additionally, we provide solutions with both metallic sleeves and carbon fiber sleeves.

High Performance Permanent Magnets

Our rotor assembly portfolio includes rare-earth magnets such as neodymium magnets and Samarium-Cobalt to ensure maximum magnetic field strength and excellent performance. Our multipole ring magnets provide a uniform magnetic field and contribute to enhanced motor efficiency. In addition to radially magnetized ring magnets, we also offer polar-anisotropic ring magnets (also known as halbach ring magnets). We also manufacture laminated magnets for high temperature motor applications.

Stringent Quality Control

We adhere to strict quality control measures throughout the entire production process, from raw material selection to final product testing. This commitment to quality ensures that our permanent magnet rotor assemblies meet or exceed industry standards and client expectations.

Rotor Retaining Sleeve

We recognize the critical importance of a rotor retaining sleeve in high-speed SPM machines, as it plays a crucial role in preventing structural failure. To meet various requirements, we offer a diverse range of rotor sleeves, including stainless steel, titanium alloy, inconel, and carbon fiber options. Our sleeves are designed to accommodate both segment magnets and ring magnets, providing flexibility and efficiency for different permanent magnet rotor configurations.
