A small locomotive that makes a big impression Building a model train system on scale 1:160 (N gauge) involves working with very small units.
High-performing micro drives In the case of the model locomotive featured here with a weight of just 36 g and a relatively high engine speed, quiet running is a particular issue. Saturday, May 8th, 2010 is National Train Day and there will celebrations around the country in major train stations, small depots, and transportation museums around the country.  You can read my column on the festivities – Marking Americans’ love affair with the rails , but here are a few highlights and a few bonus photos. Amtrak is celebrating National Day Train Day with free events that include model train displays, tours of private railroad cars, cooking demonstrations and a wide range of other activities at train stations in New York, Washington, DC, Philadelphia, Chicago and Los Angeles.
At Philadelphia’s 30th Street Station, there will an exhibit titled Baseball Junction: The History of Baseball and the American Railroad with memorabilia, photos and videos. At Chicago’s Union Station, they’ll be talking about the role train travel played in the history of blues music in America.  Posters and other memorabilia from the Chicago Blues Museum will be on display and there will be a performance of train-themed blues songs by Big Bill and Larry “Mud” Morganfield, who are the sons of legendary blues musician Muddy Waters.
We have 12 professional motor factory production of different motor to meet the needs of different industries and fields of civil and military needs. YT series three-phase asynchronous motor is newly developed by employing up-to-date techniques with individual fully enclosed fan. We are a major supplier of electric motors and gear reducers and pumps for civil water control and water supply and sewage control. Depending on the use, a wide choice of toy trains and exceptionally faithful replica models is available.
In this case, the BR 70 locomotive in N gauge is only approximately 57.8 mm long when measured buffer to buffer. Even the slightest imbalance in the rotor on this lightweight locomotive will cause vibrations and possible resonance within the model railway system on which the rails are laid.
The sooner drive specialists are involved in developing an application, the smoother the process of integrating the drive. However, Tradekey respects the intellectual property, copyright, trademark, trade secret or any other personal or proprietary third party rights and expects the same from others. As one of the leading providers of high-end model train systems, Nuremberg-based Fleischmann has now developed a new model.
In this way, specific key characteristics such as special configurations, short-term overloading, extremely quiet running, etc. Modern electronics allow a large number of locomotives to be controlled digitally with no complex wiring or different power supplies. Their miniature replica in N gauge of the Bavarian 70 series locomotive (BR 70) from 1930 is both convincing and highly detailed. It is nevertheless essential that every detail is accurate and that the model’s driving performance is appropriate.
A micro drive in the model locomotive provides the link between the electronics and the mechanisms, enabling delicate shunting operations and interurban journeys with many wagons to be replicated accurately to scale.

Even the lettering measuring just tenths of a millimeter high can be read perfectly with a magnifying glass. The locomotive’s undercarriage and body are die-cast in metal with added plastic parts. Thanks to this exact design, the motor and flywheel are as large as the locomotive body permits.
Although ready-made drives meet many requirements, for high-end and specialized applications,customization is the answer. The advantage of this approach is that the large flywheel, which stores kinetic energy, delivers excellent running performance over points and sets of points, even during very slow shunting operations.
Microdrives are no longer limited by technology – instead it is up to developers to find new creative possibilities, not just in model making. Major strides have been made in development here, with the professional model makers at Fleischmann bringing micro drive specialist FAULHABER into the developer pool for this very purpose. This is particularly important when there are brief interruptions in the power supply from the track. This enabled a specific tailored concept to be formulated that considered drive requirements, model size and characteristics right from the start. A version of this locomotive with an integrated digital decoder is specially adapted to the drive motor running in this way to make the slowest movements appear more realistic. When it comes to the drive, certain mechanical and physical conditions need to be considered.
Effortlessly absorbing the axial forces of the first worm gearing stage, the motor’s durable, lifetime-lubricated bearings enhance this microdrive, which has been optimized for model making. As on large locomotives, traction (and, on the model, power transmission) between the wheel and the track is a crucial factor.
The engine speed must now be geared down relative to the model scale and the size of the drive wheels. Other electronic components can transmit digital control signals to the drive or lights and auxiliary equipment, for example. 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.
