Kollmorgen DBL3H00250QR2000S40
Product Introduction:
The DBL series are rugged, high-performance brushless servo motors with smooth rotor surfaces and very low cogging. The DBL3 frame is a mid-size (approx. 130 mm flange). “H” denotes a winding optimized for 230/400 VAC (320 VDC bus typical), “00250” = 2.5 kW rated power, “Q” = resolver feedback (or resolver+encoder per option table), “R2000” = 2000 line encoder/feedback option, “S40” = SpeedTec M23 connector, IP65, with brake omitted (no -B suffix).
Detailed content

Installation & Notes:
-
Compatible with SERVOSTAR S300/S400/S700 and AKD drives (verify feedback pinout — DBL uses resolver or Hiperface/EnDat with option card).
-
Legacy product — AKM or AKM2G are recommended successors for new designs.
-
Ensure motor shaft is aligned to load coupling to avoid side loads exceeding bearing spec.
