The W22 Brake Motor combines the WEG W22 platform with a high-torque, long-life electromagnetic brake. It is designed for equipment that needs rapid stops for safety, accurate positioning and shorter cycle times.
The brake is normally closed: when the motor is switched off, the coil current is interrupted and springs push the armature so that the brake disc is clamped between the armature and the non-drive endshield. On restart the coil is energised together with the motor, the armature is pulled in and the disc is released. The coil is fed with DC through a compact bridge rectifier that fits inside the main terminal box and tolerates supply variations of up to 10%.
The brake version keeps the W22 features: a frame that improves cooling airflow, a roomy terminal box, solid feet for easy alignment and a rigid, low-vibration frame. An optional manual release lever and a microswitch that monitors brake opening or wear are available. Euronorm supports brake torque and frame selection and provides quotations.
Features
Normally closed brake
Springs clamp the brake disc when power is removed, so the load is held safely during outages.
Standard torques per frame
Brake torques are defined per frame size to deliver short braking times.
Fewer moving parts
A low-wear friction element and simple design reduce maintenance downtime.
Compact rectifier
The bridge rectifier mounts in the main terminal box and operates with voltage variations of up to 10%.
Manual release and monitoring
An optional lever frees the shaft in emergencies and a microswitch signals brake wear.
W22 platform
The rugged FC-200 cast iron frame, solid feet and low vibration levels are retained.
Applications
- Load elevators, hoists and lifting equipment
- Conveyors and packaging machines
- Shears, bending and machining equipment
- Looms, washing and bottling machines
