YEJ2 Series Electromagnetic Brake Three-Phase Asynchronous Motor

Product Overview

YEJ2 series electromagnetic brake three-phase asynchronous motors integrate a fail-safe DC brake mechanism for rapid stopping and precise position holding in applications requiring safety and control.

Key Features

Integrated electromagnetic disc brake providing instant stopping within 0.2 seconds
Fail-safe spring-applied brake engaging automatically upon power loss for safety protection
Manual release lever allowing manual rotation during power outage or maintenance procedures
Adjustable braking torque settings accommodating different load and inertia requirements
Separate rectifier module converting AC supply to DC for reliable brake coil operation
Maintenance-free brake lining with extended service life exceeding 2 million engagement cycles
Compact integrated design saving installation space compared to separate motor-brake assemblies
Low noise brake engagement minimizing operational disturbance in workplace environments
Suitable for vertical lifting applications preventing dangerous load drop during power failure
