Servo Motor Adapter (MB) with ServoSTOP Brake
- The holding current brake is integrated into the motor adapter.
- Functions as a holding brake.
- Capable of braking from full speed, e.g., in case of a voltage drop or emergency shutdown in hazardous situations.
- Can operate as a single brake or in combination with a motor brake as a redundant braking system.
- Electrically activated for dry operation.
- Features a backlash-free plug-in coupling (jaw coupling) for easy motor removal with the shaft held in any position.
- Electric release monitoring in the terminal box via a non-contact, wear-resistant proximity switch.
- Manual wear inspection by checking the air gap with a feeler gauge.
- Radial shaft sealing rings made of FKM with two sealing lips.
- Four oil drain holes prevent brake contamination in case of an oil leak.
- Differential-redundant system in compliance with EN ISO 13849-1.
- Standard electrical connection via terminal box, optionally as a plug-in connector (not possible with release monitoring).
- In a de-energized state, braking is performed by spring force.
- Released by a DC electromagnetic coil before motor startup.
- Motor plug connectors or adapter terminal box/plug connector are mounted in the 270° position.
- When combined with a motor brake, it provides a dual-brake system with an exceptionally compact design.
EZ Servo Motors
- Permanent magnet synchronous electric motors.
- Rotating plug connectors with quick-lock mechanism.
