Anti-Lift & Anti-Theft Protection
This brushless industrial door motor is designed for industrial lifting doors, sectional doors and other automatic door systems that require reliable vertical lifting without a conventional torsion spring.
The motor works with a dedicated lifting mechanism and matching mounting brackets, allowing the door to be raised and lowered directly through the motor-driven system. Compared with traditional door systems that rely on torsion springs for counterbalance, this design removes the need for a separate torsion spring installation.
The result is a cleaner installation, fewer mechanical components and a more straightforward setup for industrial door manufacturers, installers and system integrators.
The available motor configurations cover different door weights and lifting requirements, making the system suitable for a range of industrial lifting door applications.
Brushless Industrial Door Motor Without Torsion Spring
The main difference between this system and a conventional industrial door operator is the lifting structure.
Traditional industrial lifting doors commonly use a torsion spring to balance the door weight. The spring system requires additional installation space and must be correctly matched and adjusted during installation.
This industrial door motor uses a motor-driven lifting arrangement instead. The matching bracket plates and lifting components are designed to work with the motor as a complete system, eliminating the need for a conventional torsion spring. For door manufacturers and installation contractors, this can simplify the mechanical structure and reduce the amount of work required during installation and commissioning.
Four Practical Advantages of the Torsion Spring-Free Design
01
Reduced Installation Cost
Removing the conventional torsion spring can reduce the number of components required for the door lifting system. It also reduces the installation work associated with spring positioning, adjustment and commissioning. For projects involving multiple industrial doors, a simpler mechanical configuration helps reduce both material and labor costs.
02
Simpler & Efficient Installation
The motor, mounting components and lifting mechanism are designed to work together as a complete drive solution. The torsion spring-free structure makes the installation process more straightforward and reduces dependence on complicated spring adjustment during setup.
03
Improved Door Safety
Conventional springs store high mechanical energy. By removing the torsion spring, this solution reduces components under spring tension. The system also incorporates a dedicated safety brake device to help control the door during lifting operation and prevent unexpected falling.
04
Anti-Lift & Security Upgrade
The motor-driven lifting structure provides controlled operation of the industrial door and helps prevent unauthorized manual lifting from the outside. This makes the system ideal for factories, warehouses, logistics buildings and commercial facilities requiring heightened security.
Industrial Door Motor Models and Specifications
The available brushless industrial door motors are designed for different lifting capacities:
| Model | Rated Torque | Motor Power | Suitable Door Weight | Maximum Lifting Height |
|---|---|---|---|---|
| JMJ60DT-AD-LHWS | 60 N·m | 300 W | Up to 120 kg | Up to 6 m |
| JMJ92DT-AD-LHWS | 92 N·m | 400 W | Up to 200 kg | Up to 6 m |
| JMJ107DT-AD-LHWS | 107 N·m | 700 W | Up to 400 kg | Up to 9 m |
* Selection Note: The appropriate model should be selected according to actual door weight, lifting height and mechanical configuration. For new projects, providing door dimensions and weight allows pre-evaluation before ordering.
Integrated Components & Safety Features
Matching Brackets & Complete Drive System
The industrial door motor is supplied as part of a matching lifting system rather than an isolated motor unit.
Different mounting and lifting components are available to suit the installation structure. The matching bracket plates help connect the motor and lifting mechanism directly to the door assembly, giving OEM manufacturers maximum flexibility during integration.
Dedicated Safety Brake Device
A safety brake device is integrated into the drive system as an essential mechanical safety component.
The brake controls the lifting mechanism and protects against uncontrolled movement or accidental falling of heavy door panels. For door manufacturers and integrators, the safety brake is an integral structural safety component rather than an aftermarket accessory.
