Kollmorgen KBM-79H03-E03
-
Product Name: KBM Series Frameless Direct Drive Permanent Magnet Motor (Outer Diameter approx. 79mm class, H stack, E03 config).
-
Product Introduction: A frameless (kit) motor consisting of a stator and rotor only, designed to be integrated directly into a machine’s structure (e.g., inside a gimbal or spindle) eliminating couplings and gearboxes.
Detailed content
-
Technical Specifications:
-
Torque Range: Optimized for medium torque density (specific Nm depends on wind/h stack; KBM-79 class typically serves compact high-precision axes).
-
Voltage: Compatible with 320-640 Vdc bus typical of AKD/S300 drives.
-
Speed: High-speed capability, often >2000 rpm depending on load.
-
-
Material & Structure: Neodymium iron boron (NdFeB) magnets, epoxy encapsulation, non-magnetic stainless steel rotor hub.
-
Working Principle: Direct electromagnetic drive; rotor is mounted directly on the load axis, providing zero backlash.
-
Applications: Semiconductor wafer handling, optical scanning, medical CT gantries, aerospace gimbals.
-
Installation Requirements: Critical air gap alignment (typically <0.5mm tolerance); bearings must be supplied by the machine structure; precise concentricity is mandatory to avoid magnetic pull and vibration.
-
Notes: No integral cooling or sealing—rely on machine enclosure; handle magnets with care (strong attraction); ground stator windings properly.
