Tamiya 72101 description featuring Geared Motor 380K75 and sponge tyre set

The Tamiya 72101 kit supplies two geared 380K75 motors together with sponge tyres, aimed at model builders and robotics hobbyists. The 380K75 is specified for DC7.2V operation, with an unloaded rotational speed of 242 rpm and maximum torque of 5.0 kg/cm, allowing the pair to support an approximate total weight of 4kg for demonstration or light competition use.

Design considerations and project use

Suitable for building compact competition bots or carrying out practical lessons in mechanics, each motor-wheel unit is capable of supporting around 2kg. The kit includes motor mounts, wheel hub shafts and necessary assembly components to aid installation into a variety of small chassis projects.

  • Motor Type: Geared Motor 380K75
  • Power Source: DC7.2V
  • Rotational Speed: 242 rpm (unloaded)
  • Max Torque: 5.0 kg/cm
  • Total Weight: 480g

What does the 5.0 kg/cm torque mean for performance?

The 5.0 kg/cm figure indicates the motor's peak torque capability and helps predict its ability to move loads and overcome resistance. In practice, gearbox losses and applied voltage affect real output.

Which power source is required for the 380K75?

Use a DC7.2V supply as specified. Keeping voltage within this range ensures expected speed and torque while protecting the gearbox and motor life.

Any tips for mounting and alignment?

Align the motor shaft and wheel hubs carefully, tighten mounts to avoid slop and check wheel alignment before running. Proper mounting reduces wear and improves handling.
