Core Features & Benefits

Medium Inertia Design for Versatile Applications

The EMJ-08APB22 features a medium inertia rotor, specifically optimized for applications requiring balanced performance between rapid acceleration and stable load handling. This design provides enhanced stability for general automation and CNC applications.

300% Overload Capacity

With a peak torque of 7.17 N*m (300% of rated torque), this motor handles demanding acceleration requirements and sudden load fluctuations without stalling. The high overload capacity ensures reliable operation in applications with intermittent high-torque demands.

Built-in Holding Brake

The "B" in the model suffix indicates this unit includes a 24V DC holding brake, making it ideal for vertical axis applications where the load must be held in position when the servo is disabled.

Prevents load drop in vertical applications (Z-axis, lifting mechanisms)
No external brake mechanism required
Automatic engagement when power is removed
Essential for CNC machine tools and robotics applications

High-Speed Operation

With a maximum speed of 4500 RPM (rated speed 3000 RPM), the EMJ-08APB22 can handle high-speed machining and fast positioning applications, improving machine throughput and cycle times.

IP65 Environmental Protection

Rated IP65 as standard configuration, the motor is protected against dust ingress and low-pressure water jets from any direction. This makes the EMJ-08APB22 suitable for:

Dusty factory environments
Machine tool coolant exposure
Food processing machinery applications
Harsh industrial settings

High-Resolution Feedback

The standard 2500 P/R incremental encoder provides precise position and speed feedback for high-resolution control loops. Optional encoder upgrades include:

17-bit absolute encoder (131,072 pulses/rev) - retains position after power loss
20-bit incremental encoder (1,048,576 pulses/rev) - ultra-fine positioning

Robust Mechanical Construction

Oil seal included as standard - prevents lubricant ingress, suitable for gearbox or pulley-coupled applications
Key-way shaft - positive torque transmission
Fully enclosed construction - reliable operation in demanding environments

Applications

The Estun EMJ-08APB22 is engineered for high-cycle industrial automation applications requiring medium inertia performance and holding brake functionality.

Primary Applications

CNC Machine Tools - Feed axis drives for milling machines, lathes, and routers; successfully integrated with Centroid Acorn6 CNC controllers
Vertical Axis Systems - Lifting/lowering mechanisms, Z-axis stages - the holding brake prevents load drop when power is removed
Robotics - Small to medium robotic arms, articulated joints, and pick-and-place systems
Packaging Machinery - Wrapping, filling, and labeling equipment requiring precise torque control

Additional Applications

Textile Machinery - High-speed winding, spinning, and yarn tension control systems
Semiconductor Equipment - Wafer handling and inspection systems
Material Handling - Conveyor systems, palletizers, and automated storage/retrieval systems
Food Processing Machinery - IP65-rated construction suitable for wash-down environments
Battery Manufacturing Equipment - Precision positioning for cell assembly
General Automation - Assembly line indexers, positioning stages, and factory automation systems

Wiring & Installation Notes

Do not connect the servomotor directly to the local electrical network - this may result in damage
After power is removed, residual voltage remains in the capacitor. Wait 5 minutes before inspection
Separate high-voltage cables from low-voltage cables to avoid noise interference
Single point grounding required (grounding resistance 100Ω or below)

Holding Brake Configuration

The brake interlock output signal (/BK) controls the brake
Brake timing parameters can be adjusted for servo OFF and alarm conditions
Essential for vertical axis applications
