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.

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
