1. Design and Integration
The ILM0701P11A0000 is engineered as a lightweight, high-speed servo solution, combining a brushless motor, digital drive, and 23-bit absolute encoder in a 152mm-long package. Its key design differentiators include:
Keyed Shaft Optimization:
- 14mm Keyed Shaft: Enhances torque transmission for direct-drive applications, reducing backlash in couplings.
- Low Inertia Rotor: 0.00015 kg·m² inertia enables rapid acceleration/deceleration cycles.
Encoder Technology:
- 23-bit Single-Turn Absolute Encoder: Provides 8 million positions per revolution, eliminating the need for homing sequences.
- Battery-Free Multiturn Option: Available as an upgrade (ILM0701P12A0000) for applications requiring multiturn tracking.
2. Performance Characteristics
Torque and Speed:
- The 1.1 Nm continuous torque supports steady-state operations like conveyor drives, while the 3.3 Nm peak torque accommodates rapid changes in motion profiles.
- At 6,000 rpm, it excels in high-speed applications such as labeling machines, centrifuges, and spindle drives.
Dynamic Response:
- Settling Time: <2 ms ensures precision in applications like electronic manufacturing.
- Auto-Tuning: Advanced algorithms optimize PID gains automatically, reducing commissioning time by up to 50%.
3. Applications
