Functional Features:
- High continuous torque (2.4 Nm) in a single frame — eliminates need for gearboxes in many applications
- Dual feedback: 2000 CPR incremental encoder + analog tachometer provides redundancy and velocity monitoring
- Military-grade connector (MS3106A18-10S) for rugged OEM and defense applications
- Class H insulation (180°C) supports sustained high-temperature operation
- 8-pole, 24-slot commutation delivers very low torque ripple (< 2%)
Material Composition:
- Stator: Silicon Steel Lamination (M-19, 0.35 mm), Class H enamel wire
- Rotor: Silicon Steel Lamination (M-19), NdFeB Magnets (N42SH)
- Housing: Cast Iron (GG-25), epoxy coated
- Shaft: Alloy Steel (AISI 4140), nitrided surface
- Commutator: Copper-Chromium Alloy (CuCr)
- Brushes: Precious Metal (AuPd), 10 mm x 14 mm x 25 mm
Working Principle:
120 V DC powers the stator windings, creating a rotating magnetic field that drives the NdFeB rotor. The 8-pole, 24-slot commutation ensures smooth torque delivery. The incremental encoder provides digital position/velocity feedback, while the analog tachometer provides a velocity-proportional voltage (0-10 V at 0-4000 RPM) for independent velocity monitoring. The military connector routes all signals (power, encoder, tachometer) through a single rugged interface.
Advantages:
- Highest torque in D-Series (2.4 Nm continuous) — direct-drive capability for many loads
- Dual feedback system provides fault tolerance; if encoder fails, tachometer maintains velocity control
- Military connector ensures reliable connection in vibration-intensive environments
- Class H insulation allows operation in ambient temperatures up to 50°C without derating
- Low torque ripple (< 2%) for smooth low-speed operation
Applicable Industries:
- Military / Defense Systems
- Radar Antenna Positioning
- Heavy-Duty Pan/Tilt Systems
- Shipboard Motion Control
- Mining Equipment
Installation Requirements:
- Mount on rigid base using 4 x M10 mounting holes; torque to 25 Nm
- Use torque-limiting coupling rated for 10 Nm minimum
- Connect 120 V DC bus with 6 mm² cable
- Ground housing to PE with < 0.1 Ω resistance
- Connect MS3106A18-10S connector with proper keying; do not force misaligned mating
Usage Notes:
- Brush replacement interval: 4000 hours or when commutator wear exceeds 0.1 mm
- Do not exceed 4000 RPM; this is the mechanical balance limit
- The “-01” variant has a custom shaft length (45 mm); verify coupling compatibility before ordering
- Tachometer output is 0-10 V proportional to 0-4000 RPM; calibrate in drive parameters
