Additional technical notes:
- The rotor is supplied pre-magnetized, requiring careful handling because of strong magnetic attraction.
- Mitsubishi specifies avoiding impacts to the magnet surface to prevent cracks or chipping.
- The complete TM-RBP048G20 + TM-RBS048G20 assembly operates with an approximate 1 mm air gap between stator and rotor.
- Compatible drive systems include Mitsubishi MDS-D2-V1-80, MDS-D2-V2-8040, MDS-D2-V2-8080, and MDS-DJ-V1-80 servo drive units.
- Mitsubishi provides official DXF CAD files for this exact model.
