Block Brake PM Gearless Traction Machine - The Future of Elevator Drive Systems
Overview
The Block Brake PM (Permanent Magnet) Gearless Traction Machine represents the pinnacle of elevator drive technology, combining high efficiency, compact design, and superior safety for modern high-rise buildings. This advanced system eliminates the need for gearboxes, using permanent magnet synchronous motors (PMSM) for smooth, energy-efficient operation.
Key Features
·Gearless Design - No gearbox reduces maintenance and improves efficiency
·Permanent Magnet Motor - Up to 30% more energy-efficient than traditional induction motors
·Electromagnetic Block Brake - Fail-safe braking system for maximum safety
·Compact & Lightweight - Ideal for machine-room-less (MRL) elevator systems
·Precision Control - Smooth acceleration/deceleration for passenger comfort
How It Works
Direct Drive System - The PM motor rotates the drive sheave without gears, reducing energy loss
Regenerative Braking - Converts braking energy into electricity, improving efficiency
Dual Safety Brakes - Spring-applied, electrically-released brakes engage automatically during power loss
Smart Control - Integrated with VFD for optimal speed regulation and floor leveling
Benefits Over Traditional Systems
Higher Energy Efficiency - Meets IE4/IE5 efficiency standards
Reduced Maintenance - No gearbox means fewer moving parts to service
Quieter Operation - Noise levels below 50 dB for premium buildings
Space-Saving - Compact design enables installation in tight hoistways
Longer Lifespan - Designed for 25+ years of reliable service
Technical Specifications
Speed Range: 1.0 - 10.0 m/s
Power Range: 15 - 100 kW
Braking System: Dual electromagnetic block brakes with manual release
Efficiency Class: IE4/IE5 (up to 96% efficiency)
Compliance: EN 81-20/50, ASME A17.1, GB7588

FAQ
1. Are the elevator wire ropes durable?
The elevator wire rope has special provisions and requirements. Configuration is not only for wire rope and rated load, but also considered the size of the traction, as a result, the tensile strength of wire rope is greater than the weight of the lift. The safety factor is equipped with more than four wire rope. So it won't break at the same time.
2. Is it dangerous for power failure suddenly during the elevator running?
If it occurs, the elevator will automatically stop due to the electrical and mechanical safety device. In case of power failure,elevator brakes will automatically taken. In addition, the power supply departments such as planned outage, prior notice are also operating.
3. Will us be hurt when it closed suddenly?
In the closing process, if people touch the hall door, the door of elevator will automatically restart without any danger. With anti clamping switch, once the gate touched, this switching action make the elevator unable to be closed and even reopened. In addition, closing force is also available here.
4. How the elevator running?
Elevators are operated with a counterweight wire rope through the (tractor) traction drive, making ups and downs on the guide rail.
5. Is the escalator installation complicated?
We believe the functions of an escalator are not necessarily proportional to the operation complexity. Therefore, escalators designed by us apply an integrated structure, so that the equipment is more precise and more efficient and allows easier and more convenient commissioning.
6. Do you have any cerifications?
Yes, we do with ISO9001 / CCC / CE Certificates for u.
