Smart Automation Solution
Servo/Motion
Servo Motor
Features
- Uses own technology to domestically produce motors, drives, and encoders
- Optimized for low-speed, high-torque and high-precision operation
- Provides power connection for the connection of DC-Link Terminal
- Compact size and easy wiring (Compared to the 3-phase AC Reactor)
- Provides connection for DC input (PI, N)
- Reduced cogging torque and optimized torque design
- Optimal ratio of the permanent magnet and coil/slot selected through electromagnetic analysis
- Uses multiple permanent magnets to reduce torque ripple and to maximize torque
- Uses a permanent magnet of high-energy rare earth elements (Nd-Fe-B)
- Using the high-performance rotary optical encoder that adopts the Biss protocol
- Resolution of 1,048,576 CPR (20bit Single turn)
- Uses our own encoder technology to reduce the cost and shorten the delivery time
- Compatible with our L7 Series AC Servo Drive (3phase AC 220V)
- Both standard I/O type (serial communication supported) and network type (EtherCAT) applicable
-
Direct Drive Structure
- No backlash impact
- High-precision operation and shortened installation time
- Smooth rotary motion
- Reduced noise
