CFRP composite protective sleeve for high speed Permanent magnet rotors

CFRP composite protective sleeve is suit for rotor protection sleeve of  permanent magnet synchronous & asynchronous motor. It size can be customized,  Bearing temperature  max 180℃.  When the rotor's speed is lower, For example 2000 rpm, or 3000 rpm,8000 rpm etc, choose stainless steel protection sleeve is good idea. Because it is lower cost. If the rotor's speed is higher, for example 20,000 rpm, 50,000 rpm, Please choose carbon fiber protection sleeve for the rotor.   Stainless steel rotor protection sleeve can't match so higher speed.

The max speed for carbon fiber protection sleeve is 100,000 rpm.

Carbon fiber tube for rotor protction's Advantage:

1. light weight, high strength,Size can be customized.

2. Can bearing high temperature-- 180 degree.

3. Conductive heat quickly

4. Non-Conductive magnet

5. Good dynamic balancing when high-speed

6. permanent magnet synchronous & asynchronous Motor rotor speed 60,000 rpm, The centrifugal deformation 0.2 mm

It suit for the motor speed > 10,000 rpm

There are two way to produce the carbon fiber  rotor cover:

1.Produce carbon fiber tube first ;Then Put the present carbon fiber tube cover the outside of rotor

2.Produce the carbon fiber cover directly outside of the rotor
