Important handling notes
The rotor is delivered pre-magnetized, so it has strong magnetic attraction.
Do not strike or drop it, as the magnet surface can chip or crack.
It must be assembled with the correct air gap with the stator (typically ~1 mm system clearance in TM-RB designs).
Cooling and torque ratings depend on the paired stator’s liquid cooling system.
