Kollmorgen AKM43G-ACCNDA-00
Product Introduction:
The AKM43G is a size 4 frame (84×84 mm IEC flange) with “G” winding (specific voltage/speed constant) and pre-assembled single-turn EnDat 2.1 (27-bit optical) encoder. It delivers high dynamic response for demanding acceleration profiles.
Detailed content
Technical Specifications:

Functional Characteristics:
-
Low rotor inertia for high acceleration
-
Minimal cogging due to optimized magnet geometry
-
EnDat encoder enables absolute position tracking without homing after power-loss (single-turn)
Application Scenarios:
-
High-speed pick-and-place
-
CNC small-axis drives
-
Inspection and metrology stages
-
Dental/medical handpiece motors (custom pack)
Structural Features:
-
Dark black coated housing (standard AKM finish)
-
Rear-mounted encoder with glass disc (handle with anti-static precautions)
-
PTC thermistor embedded in winding
Working Principle:
Three-phase sinusoidal PMSM operation with field-oriented control, using absolute encoder feedback for sub-arc-minute positioning accuracy.
Installation Requirements:
-
Shaft coupling must be non-binding
-
Encoder cable must be separated from power lines and shielded
Usage Precautions:
-
EnDat encoder is sensitive to ESD; disconnect only when powered down
-
Do not exceed 100 °C winding temperature rise
