55-piece motor kit for STEM builds

This DORHEA C kit bundles 55 coloured plastic gears, two TT gear motors, four 130-size DC motors, three AA battery holders, rocker switches, T-type clips and 1.5 metres of wire. It is aimed at hobbyists, educators and students building simple robots, vehicles or circuit experiments.

Gears, holders and switches expand project scope

The 55-piece gear set provides multiple ratios and propeller styles so a single build can be re-configured without extra parts. Three dual AA holders supply 3 V directly to the TT motors or the 130 motors, while four rocker switches and four T-clips give quick on-off and connection options for classroom demos.

Press-fit shafts and pre-stripped wire speed

TT motor shafts are 2.0 mm diameter with 7.5 mm length; 130 motor shafts are 2.0 mm diameter and 10 mm long, both designed for press-fit gear mounting. Pre-cut 1.5 m wire and crimped battery clips avoid soldering. Builders without a 3–6 V regulated supply may see the TT motors run below the 90 RPM minimum at 3 V or exceed 200 RPM at 6 V.

Questions about this item

Will the 55-piece plastic gear set need replacement if teeth strip under load?

The plastic gears can strip if torque exceeds the TT motor's 0.8 kg·cm stall rating; keep loads within the 0.15–0.60 Nm operating range to avoid early wear.

What limits continuous running time for the TT gear motors?

The 150 mA continuous no-load current at 3–6 V means heat buildup is the first limit; sustained stall at 200 mA max will overheat the windings quickly.

How much noise and heat do the 130-size motors produce at 25 000 RPM?

At 12 V the 130 motors reach 25 000 RPM with noticeable whine and warm cases; running at the recommended 3–6 V reduces both noise and temperature rise.
