• Rotor core: Laminated silicon steel sheet wound armature with carbon brush commutator assembly
• Permanent magnet: High-energy ferrite magnet fixed on stator inner wall
• Output shaft: 4140 alloy steel quenched tempered shaft with wear-resistant surface polishing
• Bearing unit: Double-row sealed deep-groove ball bearing with high-temperature lithium grease lubrication
• Brake housing: Cast aluminum alloy with electromagnetic coil and friction brake disc

Structural Characteristics

1. Flange mounting front face standard NEMA 40 frame dimension for universal mechanical installation compatibility
2. Rear end cap integrated tachometer feedback unit and brake electromagnetic coil assembly
3. Side-mounted detachable brush maintenance cover for rapid carbon brush replacement
4. Single-output solid shaft with standard parallel keyway, shaft diameter 14 mm
5. Full perimeter housing cooling fin structure for passive convection heat dissipation

Working Principle

1. 24VDC control drive outputs variable magnitude DC current to motor armature winding
2. Electromagnetic interaction between armature current magnetic field and stator permanent magnet field generates continuous rotational torque
3. Commutator and carbon brush assembly maintain constant armature current magnetic field phase angle relative to stator magnet for unidirectional rotation
4. Rear-end tachometer generator outputs analog voltage signal proportional to actual motor rotational speed, fed back to DC servo drive for closed-loop speed regulation
5. When brake 24VDC release power cuts off, internal compression spring pushes friction disc to lock output shaft for static load holding; energized brake coil pulls friction disc away to release shaft rotation

Advantage Highlights

1. Compact NEMA 40 frame size adapts to limited installation space miniaturized automation equipment
2. Flat torque-speed curve maintains constant output torque across full operating speed range
3. Integrated tachometer eliminates external velocity encoder hardware cost for closed-loop DC systems
4. Built-in spring holding brake maintains precise static positioning without continuous power consumption
5. External brush maintenance cover reduces motor disassembly downtime during routine service
6. IP65 shaft seal resists workshop dust, coolant mist and light liquid splashing

Applicable Industries

Installation Requirements

1. Mount via front NEMA 40 standard flange bolt holes, ensure flange full-surface contact with mounting fixture
2. Install flexible coupling between motor output shaft and load to eliminate radial shaft overload stress
3. Maintain minimum 30 mm rear clearance for tachometer and brake wiring harness routing
4. Motor power, brake power and tachometer feedback cables use shielded twisted pair wiring with single-point shield grounding
5. Avoid mounting motor adjacent to high-temperature heat sources (heaters, welding equipment) to prevent winding overtemperature

Usage Precautions

1. Strictly limit peak overload operation duration under 5 seconds; prolonged 300% overload causes permanent armature winding burnout
2. Apply 24VDC brake release voltage before initiating motor rotation; rotating shaft with engaged brake generates severe friction wear
3. Regular carbon brush inspection every 500 operating hours; replace brushes when residual length less than 3 mm
4. Prolonged operation above 50°C ambient temperature requires forced air cooling to avoid Class B insulation degradation
5. Do not apply axial impact load to motor output shaft; impact force damages internal ball bearing assembly
6. Store motor in dry low-humidity environment when idle for over 30 days to prevent commutator surface oxidation
