Compact Low-Inertia DJPZ Brake For Servo & Automated Equipment

Compact Low-Inertia DJPZ Brake for Servo & Automated Equipment

DJPZ series DC electromagnetic motor disc brake is a dedicated integrated brake designed for direct assembly on the non-drive end tail shaft of Y/YEJ three-phase asynchronous motors, servo and stepping motors. Different from external caliper disc brakes, it adopts integrated flange direct mounting structure, perfectly matched YEJ braking motor complete machine production. Adopts spring normally closed fail-safe principle: energize DC to pull open the friction disc for motor free rotation; cut off power, strong springs instantly compress the disc to lock motor shaft for safe parking. Built-in manual emergency release handle for maintenance when power fails, widely applied in machine tools, lifting hoists, wind turbines, metallurgy, chemical, textile and automated production lines requiring precise positioning and safety braking.

Core Competitive Advantages

Direct motor flange mounting, ultra-space-saving (Core Highlight)

Standard flange interface matches mainstream motor rear end without custom brackets. Integrate brake and motor into one unit, greatly reduce overall equipment length, solve layout limitation of compact machine cabinets. Simple bolt fixing, fast mass assembly for motor manufacturers and old motor renovation projects.

Fast response & ultra-precise positioning

Low-inertia thin disc friction structure shortens braking action time, realizes millimeter-level accurate stop positioning for CNC, robotics and winding equipment. Avoid workpiece offset, wire breakage and production rejection caused by slow or unstable braking.

Low-noise shock-absorbing running

• Internal elastic buffer pads eliminate rigid impact during electromagnetic suction and release. No harsh metal clanging noise during frequent start-stop, meet environmental noise standards for indoor precision workshops, textile and food production lines.
• Built-in manual emergency release for maintenance safety
• Independent hand release lever design. When power cuts off or equipment needs overhaul, manually separate friction disc to freely rotate motor shaft without dismounting the whole brake, greatly improve maintenance efficiency and safety.

Reliable power-off fail-safe protection

High-strength pre-compression springs provide stable static holding torque. Instant locking once power supply fails, prevent hoist cargo falling, conveyor reverse sliding and wind turbine random rotation, eliminate major production safety hazards.

Low maintenance modular design

Split snap-on friction disc, replace without disassembling the whole brake body, cut maintenance downtime;

Self-lubricating transmission components, no regular greasing required;

Integrated rectifier built inside the brake housing, no extra external rectifier cabinet to save wiring cost;

Sealed dustproof shell prevents metal dust and moisture erosion, extend service life in high-dust metallurgy and mining workshops.

Diversified customized options

Complete DJPZ specifications from small torque DJPZ114 to heavy-duty DJPZ280 series. Explosion-proof versions available for chemical and underground mine hazardous areas. Anti-corrosion salt-fog coating, IP54 dustproof and rainproof housing optional for outdoor construction machinery and wind power equipment. Multiple DC voltage specifications customizable to match different motor control systems.
