Overview
The Kpower HBL090 is a brushless servo motor for controlled positioning tasks such as robotic arm linkages. It combines metal gears, potentiometer position sensing and a 120° customizable travel range in a 40 × 20 × 39.4 mm housing. Its specified no-load speed is 0.08 s/60°, and its 4.8–8.4 V operating range helps guide power-supply selection.
Features
- Brushless motor with high-precision metal gears.
- High-speed HBL090 model with a specified no-load speed of 0.08 s/60°.
- Potentiometer position sensing and a 120° travel range, described as customizable.
- Plastic and aluminum-alloy case with two ball bearings.
- 25T horn gear spline with a 5.82 mm diameter.
