DJPZ-2000 Series Motor Disc Brakes

1. Core Function & Working Principle

, meaning it is integrated directly with the electric motor.

Electromagnetic / Spring-Applied (Fail-Safe).

When the motor is powered, DC voltage is supplied to the electromagnetic coil. This creates a magnetic field that attracts the armature, compressing the spring and releasing the brake disc.

When power is cut, the electromagnetic force disappears. The spring force pushes the armature against the friction disc, generating the braking torque to stop the motor.

The brake is equipped with a manual release mechanism, allowing for manual operation during maintenance or emergency situations.1

2. Key Technical Specifications (DJPZ-2000)

3. Key Features

Despite being mounted on the motor, it provides a very high braking torque (up to 2000 N·m), making it suitable for heavy loads.

The electromagnetic actuation provides a rapid response time, ensuring quick stops.

The brake typically operates on DC voltage. The motor接线盒 (junction box) usually contains a built-in rectifier to convert AC to DC.

Designed to be sealed against dust and moisture, ensuring longevity in harsh workshops.

4. Typical Applications

DJPZ-2000

Used in pitch and yaw systems.

For rolling mills, crushers, and conveyors.

For precise positioning and safety braking.

For emergency stopping and holding.

Metal forming machines and large packaging equipment.1

5. Maintenance & Operation Tips

Regularly check the air gap between the friction disc and the armature. If the gap is too large (due to wear), the braking torque will drop significantly. Adjust using the manual release mechanism or shims.

Inspect the electromagnetic coil for signs of burning or overheating, especially if the brake is chattering.

Monitor the wear of the friction disc. Replace it when the wear reaches the limit mark to prevent metal-to-metal contact.

Ensure the rectifier diodes are functioning correctly to provide clean DC voltage to the coil.
