Mitsubishi Electromagnetic Power Lost Brakes YS101B034GS01

Used in Mitsubishi elevator traction systems for braking control during power-off conditions.

This type of electromagnetic brake is commonly installed together with the traction machine assembly and is designed to hold the elevator safely when electrical power is removed from the system.

In some older modernization projects in Romania and Vietnam, technicians still replace this model during machine room maintenance because long-term coil aging or braking response instability may affect operation.

Unlike standard mechanical braking parts, electromagnetic power lost brakes work together with:

• traction motor
• brake coil
• control cabinet
• safety circuit system

The brake is normally released when powered and automatically engaged after power loss.

Field Maintenance Notes

During maintenance work, technicians may check this brake when:

• abnormal stopping noise appears
• brake release becomes slow
• holding force becomes unstable
• overheating occurs after repeated operation
• traction machine vibration increases

In some commercial buildings with heavy daily traffic, brake clearance adjustment is also part of regular inspection work.

Installation Attention

This model is usually associated with:

• Mitsubishi traction systems
• machine room elevators
• electromagnetic brake assemblies
• modernization replacement projects

Correct voltage and model matching should be confirmed before installation.

Improper adjustment may affect braking response and ride smoothness.

Frequently Seen in Replacement Market

In export maintenance markets across the Middle East and Eastern Europe, this brake model is often requested for:

• old Mitsubishi system repair
• traction machine maintenance
• elevator modernization stock
• emergency replacement use

Some buyers purchase together with related brake liners and coil assemblies.
