## Description

Planetary gearbox outer diameter: 9.9 mm Motor specifications: 8 x10x12 mm (M10 motor) Geared motor height: 19.5 mm (motor + gear box) Output shaft: Gear with an outer diameter of 5.35 mm (11 teeth) Reduction ratio: 1:171 Weight: 4 grams Rated voltage: DC2.5V No-load current: 40 MA No-load speed: 92 RPM Rated torque: 9.8 mN.m Maximum torque: 37.2 mN.m The following measures the motor speed under other voltages: Voltage: DC3V Current: 42 MA Speed: 110 rpm Voltage: DC3.7V Current: 48 MA Speed: 135 rpm Voltage: DC4.2V Current: 52 MA Speed: 154 rpm Voltage: DC5V Current: 58MA Speed: 180 rpm

Review: Well built, great price - Excellent little motor. Well built, and lots of torque. I have a little concern about the fact that it's only supposed to be rated for 2.5 volts according to their specs, but they give voltage vs. RPM measurements all the way up to 5 volts.180 RPM is perfect for my application, so I'm hoping that driving it at 5 volts won't shorten its lifespan too much. Regardless, this is a great little motor.
Review: Perfect for miniature automating or toys - Very good motors
