The OMJ202B Elevator Center Split Permanent Magnet Synchronous Door Machine is a high-performance linear door operator designed for modern elevator systems requiring high torque, stable synchronization, and long service life.
It adopts a PMSM direct-drive system with full closed-loop servo control, ensuring precise door positioning, smooth acceleration, and reduced mechanical wear.
The system is widely used in residential, commercial, hospital, and retrofit elevator applications, especially where installation space is limited and reliability is critical.
Core Engineering Advantages
High-Efficiency PMSM Drive System

Real-time encoder feedback
Automatic door curve generation
One-button commissioning for faster installation
Certified Safety Structure
The OMJ202B integrates multiple mechanical safety protections:
Car door lock system (prevents door opening outside leveling zone)
Anti-collision & anti-fall safety hook on door hanger plate
Passed 45kg pendulum impact test
Designed in compliance with GB/T 7588.1 / GB/T 7588.2 elevator safety standards
High Load Capability for Heavy Door Systems
Supports center-opening door panels up to:
Maximum door load: 320 kg
Suitable for:
Glass doors
Stainless steel reinforced doors
High-traffic commercial entrances
