Mechanical interface
Mechanical output interface
The motor body, transmission and output shaft have separate roles in a mechanism.
- Motor type
- brushed dc
- Shaft diameter
- 8 mm
- Body diameter

Motor performance
No-load, rated-load and stall figures retain their separate test conditions.
- Rated voltage
- 12 V
- No-load speed
- 6,000 RPM
- No-load current
- 0.25 A
- Stall torque
- 0.14416 N·m

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.
