Features & Benefits
- Medium inertia design for balanced rigidity and dynamic response, ideal for medium-load applications
- 24-bit high-resolution incremental optical encoder for precise positioning and reliable operation
- Keyway shaft for secure torque transmission, compatible with standard couplings
- Integrated oil seal for improved dustproof and waterproof performance (IP65 shaft rating)
- Robust self-tuning and vibration suppression algorithms reduce oscillation in low-rigidity structures
- Compact footprint (motor volume up to 31% smaller than predecessors) saves machine space and cost
- Full compatibility with Delta ASDA-B3 series servo drives via standard wiring and communication
Applications
Widely used in AOI inspection equipment, tool magazines, chip mounters, CNC machines, diamond cutters, winding machines, semiconductor handling, robotics, packaging machinery, textile equipment, and warehousing automation.
