MASHIMA CAN MOTORS
MASHIMA HAS ADVISED THAT THEIR MAGNET SUPPLIER CAN NO LONGER SUPPLY MAGNETS FOR FUTURE PRODUCTION BUT THEY AND I HAVE A GOOD INVENTORY SO MOTORS SHOULD BE AVAILABLE FOR SEVERAL YEARS.
Precision 5 pole motors imported by ROUNDBELL HOBBY PRODUCTS. Best selection in the U S
AVAILABLE AT BETTER HOBBY DEALERS OR DIRECT
All motors come with hardened steel double shafts. If you need a single shaft, cut off the unwanted shaft with a carborundum cut off disk similar to a Dremel #409 with the motor shaft running in the same direction as the cut off disk. If cutting near the bearing press paper on the shaft and up to the bearing to keep grit from getting in the bearing.
Selection Advice; Larger diameter and longer motors are always more powerful, have a lower top speed, lower starting speed and generally run smoother and the current draw will be about the same, determined by the load on the motor from the mechanism, not motor size. Measure the space available and compare to the dimensions or take the diagrams (below) to Kinkos and copy them to scale then cut them out and test fit. Use the biggest motor and the biggest flywheel that will fit. All have a stall current draw under 0.5 amp. at 12 volts.
A CANNON CN-22 MOTOR (1833 size) IS SHOWN AT THE BOTTOM
18 mm Flat can motors;
These powerful motors are the finest motors for HO diesels and are the basis of many well known diesel conversions. It does an equally fine job in larger steam locomotives (from 4-6-2s to 4-8-4s and 2-10-4s) and even On3 2-8-0s etc. Combined with our large flywheels, the smoothness and quietness of operation will astonish you and the 10K speed is a perfect match for 28/1 and 30/1 gearboxes.
16 mm Round can motors;
These motors are the best for upgrading medium size steam locomotives and their low 11,000 rpm speed is much better suited to normal gearbox ratios than the 15,000 rpm of the Sagami motor. This motor is the easiest upgrade for HOn3 K class 2-8-2 with open frame motors (Balboa, PFM and Westside) and makes them run as well as more modern and expensive models and will considerably slow down Westside C-25s and K-27 and Sumpter Valley 2-6-6-2s and works in the Westside Fire Train and T-1 4-6-0, NWSL 2-6-2T, 2-8-2 and 2-6-6-2.
14 mm Flat can motors;
While these motors run slightly faster and not quite as smoothly as the 16 mm round motors (above), they are the best can motor that can be installed in some models with narrow fireboxes and they are powerful enough to power small HO steam locomotives like 0-6-0s, 4-6-0s and 2-8-0s if the round 16mm won't fit.
12 mm Flat can motors;
These small motors are surprisingly smooth and powerful for their size and have been used in several brass locomotives including HO V&T 4-6-0s and Overland HOn3 C&S 2-8-0s as well as N scale E and F units and the PSC HOn3 Galloping Goose.
10 mm Flat can motors;
These new flat can motors are specifically designed for N scale but are also very useful for small HO/HOn3 critters. These motors use rare earth magnets for far greater power and lower top speed than would be expected from this small a motor but the starting speed is fairly high. The FM-1020F(ast) and FM-1024F(ast) use Alnico magnets, have less torque and a higher top speed but also have a lower starting speed. The FM-1020F is used in the new Athearn N scale SD-70M.
9 and 10mm 5 pole motors;
This series of motors is perfect for N scale conversions and has been used in some HOn3/HOn2.5 Jonan models(Climax and 0-4-0Ts). These motors are not mounted in an enclosing can because that would reduce the armature diameter that could fit inside an N scale locomotive and the slower speed and greater power of the larger diameter armature is more important.

CANNON CN-22 CAN MOTOR:
Most Korean diesels made by Samhongsa and many by other factories
and some steam locomotives used a Cannon CN-22 can motor that measures 18mm x 33mm. They run
supurbly (comperable to the Mashima FM-1833) but getting an exact replacement for occasional
failures has been difficult.
We have developed a source for this motor and offer them to the model railroad industry. They have
a 2mm output shaft and we offer several versions.
CN-22A with a single 8mm long output shaft $34.95
CN-22B with two 22mm long output shafts $44.95
CN-22C with a 10mm long shaft on the brush end and a 34mm shaft out the front $44.95
This motor is specifically designed for steam locomotive gearboxes (NWSL 136 - 151 gearboxes with the
144-6 & 164-6 2mm shaft conversions) where the long shaft presses into the worm and both shaft bearings
in the gearbox and the whole motor gearbox becomes a single unit.See NWSL gearboxes The rear shaft can
mount a flywheel, See flywheels with 2mm holes
