PC-T085CN008-48A-SA-80
Frameless Motor Rotary Actuator
Specifications:
- 94mm Frame Size
- 53mm Length
- 24Nm Rated Torque
- 48VDC Bus Voltage
Features and Benefits:
- High torque to weight ratio
- Integrated strain wave gear
- Large thru-bore shaft
- Compact & lightweight
- Encoder, hall sensor and thermistor available
Features and Benefits
This rotary servo actuator pairs a strain wave gear with a performance-matched Lin Engineering frameless torque motor, delivering precise, high-torque motion in a compact, low-profile form factor. The actuator features zero backlash, an 80:1 gear ratio, and high torque density. A large center through-hole allows for easy routing of cables, tubing, or optical paths directly through the axis of rotation, simplifying system design and integration.
