Working Principle

Material & Structural Characteristics

• Stator core: Silicon steel laminated low-loss electromagnetic sheet
• Rotor magnet: Sintered neodymium rare-earth permanent magnet
• Motor housing: Die-cast aluminum alloy with black hard anodized anti-corrosion coating
• Shaft material: High-strength carbon steel with surface quenching anti-wear treatment
• Sealing components: Fluorosilicone rubber oil-resistant IP67 shaft seals
• Terminal connectors: Nickel-plated metal M23 circular connectors with integral cable strain relief

Core Advantages & Highlights

1. Class-leading torque density within 84 mm frame size, reducing machine footprint
2. IP67 full-body sealing permits direct installation in washdown manufacturing environments
3. 16-bit absolute encoder eliminates homing sequence required for incremental encoder systems
4. F-class winding insulation extends service life under high-duty-cycle continuous operation
5. Full mechanical interchangeability with all AKM42 frame variant models

Applicable Industries

Installation Mandatory Requirements

1. Mount flange surface flatness tolerance ≤0.02 mm; use flat mounting gasket to eliminate axial vibration
2. Shaft coupling radial runout ≤0.05 mm to prevent bearing premature wear
3. Maintain minimum 10 mm clearance around motor housing for natural convection heat dissipation
4. Torque M23 connector locking ring to specified 3 N·m tightening torque to retain IP67 sealing integrity
5. Ground motor housing via dedicated PE protective earth wire to suppress EMC interference

Operation & Maintenance Precautions

1. Do not exceed 3-second peak overload torque duty cycle to avoid permanent magnet demagnetization
2. Prevent chemical cleaning solvents from contacting shaft seal and connector rubber components
3. Perform bearing lubrication maintenance every 8,000 operating hours under continuous high-speed duty
4. Avoid prolonged storage at temperatures below -25 °C which hardens rubber sealing elements
5. Disconnect drive power before detaching M23 connectors to prevent encoder circuit damage
