🔧Application Scenarios

🏭CNC Machining Center

A precision CNC milling machine uses the Baldor ASR SYN 2-3 as the spindle motor.Paired with a MicroFlex e100 servo drive,it delivers consistent torque from 0 to 3000 RPM,enabling smooth cutting across various materials.The high-resolution encoder ensures accurate speed control and position feedback during threading and contouring operations.During a high-speed aluminum cut,the motor maintains stability even under sudden load changes,thanks to its high dynamic response.

🤖Robotic Arm Joint Drive

In a 6-axis industrial robot,the ASR SYN 2-3 powers the shoulder joint(Axis 2).Its high torque-to-inertia ratio allows rapid acceleration and deceleration,critical for fast pick-and-place cycles.The IP65 rating protects against coolant mist and dust in the factory environment.The integrated encoder provides real-time position feedback to the robot controller,ensuring repeatability within±0.01°.

🛠️Installation,Maintenance&Support

Installation:

Align motor shaft carefully with load(use laser alignment if possible).

Use proper torque on mounting bolts and shaft fasteners.

Connect power(U/V/W)and feedback(encoder)cables per drive manual.

Ground the motor frame securely.

Maintenance:

Check for unusual noise or vibration.

Inspect encoder cables for damage.

Monitor motor temperature(should not exceed 100°C under load).

No routine maintenance required on bearings(lubricated for life,typically 20,000+hours).

Troubleshooting:

Motor not turning?→Check encoder connection,drive enable signal,and phase wiring.

Overheating?→Verify load inertia match,cooling,and duty cycle.

Position error?→Re-tune PID loop or check for mechanical backlash.

📦Availability&Legacy Note

The ASR series has been largely succeeded by ABB’s Omnicore and Mint-based servo systems,but the ASR SYN 2-3 remains in use and available as new surplus,refurbished,or through industrial automation suppliers.

Replacement Tip:For modern upgrades,consider ABB’s M2000 series servos or Kollmorgen AKM2G as drop-in replacements with improved efficiency and connectivity.
