Carbon fiber tube for Rotor protection sleeve of permanent magnet synchronous & asynchronous motor

this products is suit for rotor protection sleeve of  Permanent magnet synchronous & asynchronous motor. It size 56.8*55.6*100mm. Bearing temperature 180℃, rotor speed  20,000r/min.  When the rotor's speed is lower, for example 2000 r/min, or 3000r/min,8000 r/ min  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 r/min, 50,000 r/min, 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 r/min.
