DJPZ-30 Motor Disc Brakes

⚙️ Product Overview

The DJPZ-30 is an Electromagnetic Disc Brake specifically designed to be mounted directly onto the non-drive end (tail) of electric motors. It is part of the DJPZ series, which is widely used to create YEJ series electromagnetic braking motors.

The model number typically indicates:

DJPZ: The series designation for Motor Disc Brakes (Electric Motor + Disc Brake).

30: The nominal Braking Torque of 30 N·m.

This brake is a compact, "fail-safe" device used to achieve rapid stopping and precise positioning of machinery.

💡 Key Features & Characteristics

Fail-Safe Operation (Normally Closed):
The brake operates on a spring-applied, electrically released principle.

Power Off: Springs press the friction disc against the motor end-shield, engaging the brake automatically. This ensures safety in the event of a power failure.

Power On: The electromagnetic coil energizes, pulling the armature and releasing the friction disc, allowing the motor shaft to rotate.

Motor-Mounted Design:
Unlike industrial caliper brakes that mount to a frame, the DJPZ-30 is designed to bolt directly to the IEC standard motor flange. It acts as an integrated unit with the motor.

Manual Release:
Equipped with a manual release mechanism (usually a screw or lever). This allows an operator to physically disengage the brake when power is off, which is essential for installation, adjustment, or manually moving a load during a power outage.

Compact & Maintenance-Free:
The design is space-saving and enclosed, protecting the friction surfaces from dust and oil. It typically requires no manual adjustment for wear (self-adjusting or long-life linings).

Fast Response:
The electromagnetic actuation provides a very quick response time, suitable for high-frequency start-stop applications.

🏭 Typical Applications

The DJPZ-30 is suitable for small to medium-sized motors (typically IEC frame sizes 90 to 112, approx. 1.5kW to 4kW) used in:

Lifting Machinery: Small hoists and winches.

Conveyors: Belt conveyors requiring holding torque.

Packaging & Printing: Machines requiring precise positioning.

Textile & Food Machinery: Where rapid stopping is necessary for safety or process control.

Cranes: Travel mechanisms for light-duty cranes.

📋 General Technical Specifications

Note: The DJPZ series is distinct from heavy-duty industrial caliper brakes (like the DCPZ or YP series). The DJPZ-30 is specifically a motor brake, meaning it is sized to fit on the back of a motor rather than clamping a large standalone disc. Ensure the motor shaft length and flange size (e.g., B14 or B5) match the brake's specifications before installation.
