Guidance to help you shortlist. The basis is shown for each recommendation.
Robotics and motor control
Built-in driver with dual 14-bit encoders on a 5 Mbps CAN / CAN-FD bus and a 3 kHz control loop: joints are commanded and read back over one bus.
Engineering inferenceNo-load speed, rated performance and stall limits describe different operating points. A stall specification is not a continuous operating rating.

Motor performance
No-load, rated-load and stall figures retain their separate test conditions.
- Rated voltage
- 48 V
- No-load speed
- 60 RPM
- Continuous rated torque
- 4 N·m
- Rated-load speed
- 40 RPM
- Rated current
- 2 A
Stall torque and current are not continuous ratings. Check the duty cycle and starting load when choosing the driver and power supply.
Thermal limits by level
Product operating conditions, chip ambient ratings, package case limits and junction maxima remain separate.
