Motor performance
No-load, rated-load and stall figures retain their separate test conditions.
- Rated voltage
- 16 V
- Continuous rated torque
- 0.065 N·m
- Rated-load speed
- 560 RPM
- Rated current
- 0.5 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.
