Working Principle

Material & Structural Composition

• Motor stator core: Cold rolled silicon steel laminated sheet with high magnetic permeability
• Rotor: High-performance rare earth neodymium permanent magnet embedded rotor structure
• Motor housing: Die-cast aluminum alloy with surface anti-corrosion oxidation treatment
• Encoder unit: Sealed dust-proof optical rotary encoder with metal protective shell
• Output shaft: Medium carbon steel quenched and tempered anti-wear transmission shaft with surface rust-proof coating

Advantage Highlights

1. 300% instantaneous overload torque provides powerful instant starting capacity for high inertia load rapid positioning
2. IP65 full body protection eliminates additional protective housing installation cost for harsh production workshop
3. Low torque ripple ensures stable precision conveying of fragile semiconductor and electronic components
4. Complete compatibility with all YASKAWA Σ-II servo drive amplifiers without parameter matching adjustment
5. Compact 60 mm flange small volume saves equipment mechanical structure installation space

Applicable Industries

Installation Mandatory Requirements

1. Motor flange mounting surface flatness tolerance ≤0.02 mm, four fixing bolts torque uniform 4 N·m
2. Coupling connection between motor shaft and load must adopt elastic coupling to avoid rigid transmission axial stress
3. Power cable and encoder feedback cable use dedicated YASKAWA shielded servo cable, separate wiring trough layout
4. Reserve ≥50 mm ventilation gap at motor rear end cover for heat dissipation air circulation

Operation & Maintenance Precautions

1. Avoid continuous operation under 300% overload state over 30 seconds to prevent stator winding insulation aging
2. Regularly check encoder cable connector locking nut tightness to prevent signal loose contact position drift
3. Do not wash motor body with high-pressure water gun directly; only wipe surface with damp soft cloth
4. Replace motor bearing grease every 8000 operating hours for continuous 24-hour production line equipment
