Product description: Polyol HPCB 75:1 double-sided shaft motor
Polol's small, lightweight yet powerfulenginesare used as drive units by robot constructors. The units can be supplied with voltage up to9 V, the useful power is above 3 V. The optimum voltage at which the power to strength ratio is best is 6 V. This version has an extended shaft with a length of 5.0 mm, allowing the installation ofspeed sensors - encoders.
Motor dimensions
The motor body is a26 x 12 x 10 mmcuboid. The gearbox is 9,27 mm long. There is a 3 mm D-shaped shaft at the output. Total weight is about 10 g.
