Product description: Polol 50:1 double-sided shaft
Polol's small, lightweight, yet powerful motors are used by robot constructors as driving units. The units can be supplied with voltage up to 9 V, the useful power is over 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 4.5 mm, which allows the installation of speed sensors - encoders .
Motor dimensions
The motor body is a 24 x 10 x 12 mm cuboid. The gearbox is 9,27 mm long. There is a 3 mm D-shaped shaft at the output. Total weight is about 10 g.
The drawing shows the dimensions of the Polol micro motor with gearbox.
