DJPZ-80 Motor Disc Brakes

DJPZ-80 motor disc brakes

The DJPZ-80 is a compact, fail-safe electromagnetic disc brake specifically designed for direct integration with electric motors. It is widely used to provide precise stopping and holding capabilities for motor-driven machinery.

The model number breakdown is as follows:

DJPZ: The series designation for an electromagnetic motor disc brake.

80: Indicates the specific motor frame size or shaft height of 80 mm, ensuring a perfect fit for standard IEC 80 frame motors.

💡 Key Features & Characteristics

Fail-Safe "Normally Closed" Operation:

Power-to-Release, Spring-to-Brake: When the motor is running, the electromagnetic coil is energized, pulling the armature plate against the spring force and releasing the friction disc (open the brake). When the power is cut (during a stop or a power outage), the electromagnet de-energizes, and the strong spring force instantly clamps the friction disc to stop and hold the motor shaft.

Safety First: This fail-safe design automatically prevents the load from coasting or dropping in the event of an unexpected power failure, making it highly reliable for vertical lifts and precision machinery.

Compact & Integrated Design:

Space-Saving: Designed to be mounted directly on the non-drive end (rear) of the motor, saving significant installation space compared to external drum or disc brakes.

Quick Response: Features a short switching time, allowing for rapid and precise start-stop operations.

Robust & Maintenance-Friendly Design:

High-Quality Materials: Built with high-strength components and precise manufacturing to ensure stable operation and a long service life.

Easy Maintenance: The friction linings (brake pads) are typically made of non-asbestos materials, making them environmentally friendly and easy to replace when worn out.

Customizable Options: Often available with various coil voltages and optional features like manual release devices for maintenance purposes.

Environmental Adaptability:

Designed to operate reliably in standard industrial ambient temperatures (typically -20°C to +40°C) and normal humidity conditions.

🏭 Typical Applications

The DJPZ-80 is essential for various motor-driven applications requiring precise control and safety:

Lifting & Transport: Small hoists, winches, and conveyor belts where holding a load during a power cut is critical.

Automation & Robotics: Robotic arms, automated guided vehicles (AGVs), and packaging machinery requiring rapid and accurate stopping.

General Industrial Drives: Machine tools, textile machinery, and food processing equipment driven by standard IEC 80 frame motors.

📋 General Technical Specifications

表格

Note: The DJPZ-80 is a highly standardized braking component for electric motors. When installing, it is crucial to ensure the brake's voltage matches your motor's control circuit. Regular inspection of the friction disc's thickness is essential, as excessive wear will reduce braking efficiency. Always verify that the braking torque meets the specific safety and operational requirements of your motor-driven equipment.
