Kollmorgen B-604-BA-91-VE

Product Series: B-Series (Brushless DC Servo Motor)

Product Type: Brushless DC (BLDC) Servo Motor

Product Brief:
The B-604-BA-91-VE is mechanically identical to B-604-BA-91-TE in terms of frame, stack, and performance. The only difference is the shaft configuration: “VE” denotes a smooth (non-threaded) shaft with a DIN 6885-1 keyway (key 8×7 mm).

Structural Difference from TE Variant:

  • TE: Threaded shaft (M10 × 1.0) — no keyway
  • VE: Smooth shaft (25 mm dia) with keyway (8×7 mm) — no threads

Applicable Industries:

  • Same as B-604-BA-91-TE
  • Preferred when using standard keyed couplings (e.g., jaw couplings, bellows couplings)

Installation Requirements:

  • Same mounting pattern as TE variant (4× M6 on Ø130 mm bolt circle)
  • Use keyed coupling hub matching DIN 6885-1, 8×7 mm key
  • Do not exceed 200 N radial load / 100 N axial load

Usage Notes:

  • Select VE over TE when the application requires a keyed coupling instead of a threaded mounting
  • Both variants share the same electrical and magnetic specifications
