Puts all of the locomotive's mechanical components in the trucks, making it easy to lubricate, service, or replace parts while doubling up the available traction power from the heavier weight of the mechanism made possible by the removal of any internal mechanical components.

The best motor in the world will not overcome the limitations of dirty track, a weak or inappropriate power supply, or a gearbox that’s badly-made or improperly lubricated.
This motor has a big brass flywheel attached at each end, which is fairly common as it puts the most mass possible on the drive shaft, to maintain momentum when power fluctuates.Modern N-Scale open-frame skewed-winding motor with twin flywheels mounted on the motor shaft (from an Atlas model)Types of MotorsMost motors used in model trains today are brushed DC permanent magnet motors.
These operate at maximum speeds around 10,000 rpm (some can operate at higher speeds) using gear trains to reduce the speed at which the wheels turn, and thus can be rather noisy. Older ones were also rather poor at low-speed performance, but this has been improved significantly with newer designs. Motors with different features can be optimized for specific kinds of use, or for use with specific drivetrains. Speed is measured in revolutions per minute (RPM), and for the kind of motors we care about is typically around 12,000 RPM at maximum voltage with nothing attached to the motor (this varies). Steam engines have large wheels, and so need a higher ratio to reduce the speed more, typically around 30:1 or even higher for a freight locomotive, although actual models vary widely.
Passenger steam locomotives typically ran at higher speeds and pulled less weight, and models often reflect that with lower-ratio gears (down to around 15:1, but more commonly somewhat higher).
Diesels and electric locomotives have small driving wheels, and so need less of a reduction, and thus a smaller ratio. If you reduce motor speed to 6,000 RPM (half speed), the wheels would then be turning at 500 RPM (also half speed).
I have a model with that gearing that uses 5.55 mm diameter wheels with a motor that runs at 14,000 RPM (unloaded) on 12V. These have a tendency to overheat if stalled (which can cause them to self-destruct; without a metal core to carry heat away, rotation of the armature is essential to cooling at higher currents).

Motors with steel cores (the typical kind of motor) are more tolerant of lower-frequency PWM, but they still benefit from the use of higher frequencies.PWM is used not only by DCC, but by other digital motor controllers, such as those used with Arduinos and similar hobbyist electronics. It may also be used by more advanced DC throttles, although I haven’t run across any that use it. However, they require some control system to switch the power as the motor rotates, which typically makes them more complex. Such motors have apparently been used only as replacement motors and not original equipment.
Understanding what these features are and why they may or may not matter is useful when reading manufacturer descriptions of models. Just keep in mind that quality has more to do with the attention paid to detail by the designer and builder of the model and its motor than any feature such a motor may claim. The motor in any good model train today is likely substantially better, in many different ways, than one bought thirty or more years ago. A cheap model bought today probably has a cheap motor and a cheap drivetrain, and may be worse than those older models. We’re concerned about driving the motor at some relatively small fraction of stall current (typically less than half, maybe as low as one-third). Even assuming it does provide a benefit, exactly how it does so is a topic of further uncertainty. But wouldn’t you rather have the model running smoothly when you’re actually using it? I would, and I think a small amount of break-in is beneficial.There are many things that breaking in a new locomotive could affect. Running an N-scale model designed for 12 volts on a 20+ volt system (as some HO systems are) isn’t doing the motor any favors. However, this can be harder to do with more sophisticated packs which use pulsed power, as this can trick voltmeters into misreading. If you are concerned about limiting the voltage, you could use a speed table in the decoder.
