- Peak Torque: 3.3 Nm
- Rated Speed: 3,000 RPM
- Rated Voltage: 48 VDC (bus voltage)
- Power Rating: Approximately 340 W (continuous)
- Encoder Type: Absolute single-turn, 12-bit resolution (4096 counts/rev)
- Encoder Output: SSI (Synchronous Serial Interface)
- Motor Type: Brushless DC (BLDC), slotless design
- Weight: Approximately 0.78 kg
- IP Rating: IP65 (with connector)
Construction & Materials:
- Stator: Ironless (slotless) copper windings for zero cogging torque
- Rotor: NdFeB (Neodymium) permanent magnets, high-energy grade
- Housing: Anodized aluminum alloy, lightweight
- Shaft: Stainless steel, 8 mm diameter
- Bearings: Sealed ball bearings, pre-lubricated for life
Key Features:
- Zero cogging torque due to slotless design
- High torque density: 1.42 Nm/kg
- Integrated absolute encoder eliminates homing requirement
- SSI encoder output for direct PLC/drive connection
- Wide operating temperature range: -10°C to +60°C
- High overload capacity: 3x rated torque for short durations
Applicable Industries:
- Semiconductor manufacturing
- Medical devices (robotics, lab automation)
- Packaging machinery
- CNC machine axes
- Pick-and-place systems
Installation Requirements:
- Mount using 4x M4 mounting holes on 42mm flange
- Shaft coupling: rigid or bellows coupling, max misalignment 0.1 mm
- Cable: Use shielded motor cable with encoder separate conductor
- Grounding: Motor housing must be bonded to system ground
Usage Notes:
- Do not disassemble motor; internal magnets are brittle
- Ensure bus voltage does not exceed 56 VDC (absolute maximum)
- Encoder cable must not be routed near high-current power cables to avoid EMI
