Working Principle

Material Composition

• Motor Housing: Die-cast aluminum alloy with black anodized anti-corrosion coating
• Stator Lamination: High-grade silicon electrical steel sheet to reduce iron loss
• Rotor Magnets: High-energy rare-earth neodymium permanent magnets
• Shaft: High-strength quenched alloy steel, surface ground for precision fit
• Brush Assembly: Copper-graphite composite wear-resistant brushes
• Terminal Block: Flame-retardant PA66 engineering plastic
• Bearings: Chromium alloy steel sealed ball bearings with high-temperature grease

Structural Characteristics

1. Cylindrical compact monoblock housing for space-limited equipment integration
2. Front flange mounting hole pattern for direct bolt-on installation to machine frames
3. Separated power wiring terminal area and encoder feedback connector at rear end cap
4. Sealed brush access cover for periodic brush replacement without full motor disassembly
5. Integrated heat sink fin structure on housing surface for passive heat dissipation
6. Double bearing axial spacing to suppress shaft deflection under offset radial loads

Installation Requirements

1. Mount via front flange with Grade 8 alloy steel bolts, evenly torque fasteners to prevent housing deformation
2. Maintain minimum 20mm air clearance around motor housing for natural convection cooling
3. Shaft coupling must include flexible bellows coupler to eliminate side load and axial thrust on output shaft
4. Wire power cables with shielded twisted pair; ground shield single-ended at servo drive cabinet only
5. Encoder cable separate from high-current motor power cable, minimum 15cm wiring separation to reduce EMI
6. Horizontal mounting recommended; vertical mounting allowed only with factory-specified top-side heat sink orientation
7. Ambient installation location must avoid direct liquid splash, oil mist accumulation and continuous UV exposure

Application Scenarios

• Precision rotary test stands for automotive component torque testing
• Automated rotary indexing tables for semiconductor assembly equipment
• Low-speed high-torque valve actuator drive systems
• Medical lab precision positioning rotary stages
• Winding machinery tension control small rotary axes
• Aerospace component durability fatigue test benches

Operation & Maintenance Precautions

1. Do not exceed rated peak torque for more than 3 consecutive seconds to avoid permanent magnet demagnetization
2. Check brush wear every 1,000 operating hours; replace brushes when residual length < 3mm
3. Never run motor without encoder feedback signal, as open-loop operation causes uncontrolled over-speed
4. Avoid continuous operation at ambient temperature above 65°C without auxiliary forced air cooling
5. Keep shaft keyway and coupling surfaces clean of metal debris to prevent unbalanced rotation
6. Do not apply radial impact force directly to output shaft during installation or transportation
7. Store unused motors in dry dehumidified environment with shaft horizontal support to prevent bearing indentation
