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
