Kollmorgen BH-826-D-41
Product Name: Industrial Brake or Specialized Motion Component (B-Series/H-Series related)
Product Introduction:
The BH-826-D-41 likely refers to a Fail-Safe Holding Brake compatible with Kollmorgen B-series or H-series motors, or a specific legacy component. “BH” typically denotes Brake, Holding. It is a spring-applied, electrically released device.
Detailed content
Technical Specifications (Typical for BH series brakes):
-
Voltage: 24VDC (standard)
-
Torque: Varies by size (826 might indicate size/torque code, approx. medium frame)
-
Engagement: Spring-set (fails safe on power loss)
-
Manual Release: Often available via hex key
-
Ambient Temp: -10°C to 60°C (typical)
Functional Features:
-
Zero backlash engagement.
-
Low wear friction lining.
-
Designed for vertical load holding during power off.
Application Scenarios:
-
Vertical axis of CNC machines
-
Z-axis of robots
-
Medical lifts
-
Any axis requiring position retention during emergency stop
Structure:
-
Electromagnetic coil, spring pack, armature plate, friction disc.
-
Mounts directly to motor rear or integrated into motor (AKM/BH options).
Working Principle:
When 24V is applied, the electromagnetic force overcomes spring pressure, retracting the armature and releasing the brake. On power loss, springs engage friction surfaces mechanically.
Installation & Precautions:
-
Must be wired to a safe voltage source (often via drive brake output).
-
Do not use for continuous stopping (wear will accelerate).
-
Ensure manual release is accessible if provided.
