The Tamiya 54391 Tuned Motor is crafted to deliver steady, usable power for electric RC cars, suited to practice sessions and club evenings where consistency matters. It emphasises controllable torque as much as outright speed.
The internal layout of the Tamiya 54391 makes routine upkeep easy. It uses a replaceable standard brush and accepts commutator cleaning brushes, so you can maintain good contact and performance without complex procedures.
Heat is managed through an efficient heatsink arrangement. The black motor can and the end bell help shed heat, while the heatsink brush holders add passive cooling capacity during longer runs or hot ambient conditions.
With an input range of 6.6-7.2V, expect approximately 19,400 RPM at 7.2V and a torque rating of 49 mN.m. Those metrics offer a dependable balance for a wide range of track layouts.
If you want a tuned motor that is easy to service and predictable on the track, the Tamiya 54391 is a dependable choice for club racers and hobbyists.
