Mobile robot drive trains
Mounts on the back shaft of micro metal gearmotors — the drive motors of small wheeled robots — for wheel odometry and speed control.
Engineering inferenceSpace-constrained and embedded builds
Fits within the motor's 12 mm × 10 mm cross-section on three sides and adds about 5 mm of length.
Engineering inferenceNo-load speed, rated performance and stall limits describe different operating points. A stall specification is not a continuous operating rating.
