Key Specifications
- Rated Power: 750W
- Rated Torque: 2.39 N-m (Peak torque up to 7.16 N-m)
- Rated Speed: 3000 RPM (Max speed 6000 RPM)
- Inertia Type: Medium Inertia (provides superior stability for heavy mechanical loads)
- Encoder: 24-bit high-resolution optical encoder (16,777,216 pulses/rev)
- Weight: Approximately 2.1 kg (4.63 lbs)
Key Functions
- High Torque Density: Delivers nearly 2.4 N-m of continuous torque, making it ideal for driving large ball screws, heavy conveyor sections, or industrial indexing tables.
- Load Stability: The medium-inertia design allows this motor to handle much larger mechanical loads (higher inertia ratios) without the vibration or "hunting" issues common in smaller motors.
- Precision Control: Even at high power, the 24-bit encoder ensures extreme positioning accuracy and exceptionally smooth rotation at low speeds.
Compatibility
This motor is designed to be paired with the ASD-E3-0721-L/M/E (750W) servo drive.
