Technology / product information

Metal sleeves for high-speed motors are the ideal solution for protecting and reinforcing the rotor magnets used in electric vehicles and household appliances. These sleeves adopt a thin-walled seamless pipe structure, minimizing the distance between the magnets and coils while reducing eddy current losses. This enables efficient and lightweight designs while improving motor durability.

■ Types of Metal Sleeves
- Metal sleeves for rotor protection covers
Features: Utilizes thin-walled seamless pipes to prevent the scattering of magnets in case of damage. Achieves lightweight design and minimizes eddy current losses.
Thickness: t0.05mm–0.30mm
Materials: SUS316L, SUS305

- Metal sleeves for rotor reinforcement
Features: Prevents magnet damage caused by centrifugal force and fixes securely through press fitting. Offers superior durability at lower costs compared to CFRP.
Thickness: t0.30mm–3.0mm
Materials: SUS316L, Inconel, titanium alloys

■ Features
- Thin-walled seamless structure: Achieves lightweight design while providing high durability.
- Reduced eddy current losses: Uses non-magnetic metals to improve motor efficiency.
- Flexible material and thickness selection: Options include SUS316L, Inconel, titanium alloys, and more for diverse applications.
- High performance at low cost: Provides a durable and cost-effective alternative to traditional CFRP designs.

■ Applications
- Electric vehicles: Ideal for protecting and reinforcing high-speed motor magnets.
- Household appliances: Contributes to improved efficiency in high-speed household motors.
- Others: Suitable for industrial motors and rotors requiring lightweight and high durability.
