️ Integrated Safety Brake System
On request, this gearmotor can be equipped with a state-of-the-art integrated mechanical brake, ensuring maximum safety for your operations:
- Fail-Safe Operation: The brake utilizes an electromagnetic disk design with a DC coil. It releases electrically during operation and applies mechanically via spring force. This means the brake engages automatically in the event of a power failure, meeting essential safety requirements.
- Ultra-Compact Build: A defining feature of SEW-EURODRIVE brakes is their exceptionally short axial design. The integrated construction allows for a particularly compact and sturdy assembly, saving valuable installation space without compromising on braking torque.
- Flexible Control: The brake is managed by a control element that can be conveniently installed either within the motor’s wiring space or in your central control cabinet.
️ Maintenance & Manual Release
Designed for ease of service, the gearmotor ensures that maintenance is straightforward and efficient:
- Service Access: The design ensures sufficient clearance for unimpeded air admission (cooling) and easy access for brake maintenance.
- Manual Release Options: In the event of a power outage or for maintenance purposes, the brake can be released manually. You can choose between two configurations:
