Structural Characteristics

1. NEMA 40 standard front flange mounting layout with four symmetrical fixing bolt holes for universal mechanical fixture compatibility
2. Rear end cap fully integrated with tachometer feedback assembly and electromagnetic brake coil compartment
3. Detachable side brush maintenance cover reduces equipment downtime during routine carbon brush replacement
4. Single solid output shaft with integrated parallel keyway for direct mechanical load connection
5. Full-perimeter radial cooling fin structure enables passive natural convection heat dissipation without auxiliary cooling fans
6. Separate cable routing ports for motor power, brake release power and tachometer feedback wiring harnesses

Working Principle

1. External 24VDC servo amplifier outputs variable magnitude DC current to motor armature winding assembly
2. Electromagnetic field generated by armature winding interacts with stator ferrite permanent magnet field to produce continuous rotational torque output
3. Carbon brush and commutator assembly continuously adjust armature magnetic field phase angle to maintain consistent single-direction rotation
4. Rear-mounted analog tachometer generator outputs linear analog voltage signal corresponding to real-time motor rotational speed, fed back to DC servo drive for closed-loop velocity regulation
5. When 24VDC brake release power supply is disconnected, built-in compression spring pushes friction disc to lock output shaft and eliminate shaft rotation; energized brake coil pulls friction disc away to release shaft free rotation

Advantage Highlights

1. Compact NEMA 40 frame size fits ultra-limited installation space miniaturized automation equipment
2. Flat torque-speed characteristic curve delivers stable torque output at all operating rotational speeds
3. Integrated tachometer feedback removes external velocity encoder hardware cost for low-voltage DC motion control systems
4. Spring-applied holding brake maintains static positioning accuracy without sustained power draw, reducing standby energy consumption
5. External brush maintenance cover eliminates full motor disassembly during service, shortening maintenance cycles
6. IP65 front shaft sealing withstands dust and light liquid splashing in light industrial production environments

Applicable Industries

Installation Requirements

1. Mount motor via full-surface contact of NEMA 40 front flange with rigid metal fixture, tighten four fixing bolts evenly to specified torque
2. Install elastic flexible coupling between motor output shaft and mechanical load to eliminate radial overload stress on internal bearings
3. Reserve minimum 30 mm rear clearance for routing of brake power, motor power and tachometer feedback cables
4. All motor wiring harnesses must use shielded twisted pair cables with single-point shield grounding at cabinet earth bar
5. Avoid mounting motor adjacent to high-temperature heat sources including heating elements and welding equipment
6. Maintain horizontal or vertical mounting orientation; inclined mounting above 30° restricts natural convection heat dissipation

Usage Precautions

1. Limit continuous 300% peak overload operation duration strictly under 5 seconds; prolonged high overload causes permanent armature winding burnout
2. Supply 24VDC brake release voltage completely before initiating motor rotation; rotating shaft with engaged brake generates severe friction wear and brake disc deformation
3. Inspect carbon brush residual length every 500 operating hours; replace brush modules when residual length drops below 3 mm
4. Deploy forced air auxiliary cooling fan for continuous full-load operation at ambient temperature above 50°C to prevent Class B insulation thermal degradation
5. Do not apply axial impact shock to motor output shaft; impact force damages internal ball bearing assembly and rear tachometer unit
6. Store motor in low-humidity sealed storage environment when idle for more than 30 days to prevent commutator surface oxidation and corrosion
