Motors & Gearboxes

JH

The JH is the intermediate motor in the range. It is designed for medium sized locomotives, but can be used in large locomotives where space is at a premium.

The motor can be purchased separately or combined with either a single reduction gearbox or a double reduction gearboxes. The latter units give slightly better control. Gearboxes may also be purchased separately. Flywheels for these units, which are optional extra, are available in two sizes – 22.0 mm or 28.5 mm diameter.

The single reduction gearbox suitable for this motor is available in three ratios, 18:1, 25:1 or 36:1 – the lower the number the faster the locomotive.

The double reduction gearbox suitable for this motor is available in two ratios; 25:1 & 33:1 – the lower the number the faster the drive axle revolves.

MT Helical Range

Formerly available from Ron Chaplin, this is a range of helical gearbox units mounted on the Canon EN22 motor. Helical gearboxes are mechanically more efficient than worm drive units, thereby allowing the use of a smaller motor for medium and larger size units where space is at a premium.

In addition to the range available with 3/16” wheel axles, we offer 14:1 and 30:1 two stage units with a ¼” wheel axle for Gauge 1 etc. The 14/1 ratio is very suitable for driving bogies on diesel or electric locomotives.

In addition to four ratios available for a conventionally shaped gearbox intended for steam locomotives, there is one unit that has been specifically designed for diesel and electric locomotives (including EMUs and DMUs). The gearbox has been designed in such a way that a Delrin drive sprocket (not supplied) can be fitted to the driving axle to enable a chain drive unit to be made.

These units are only available complete. A 22.0 mm diameter flywheel is an optional extra on these units.

The gearboxes in this range are available in four ratios, 22:1 2 stage, 30:1 2 stage, 30:1 3 stage or 40:1 3 stage – the lower the number the faster the drive axle revolves – final output speed is dependant on driving wheel diameter.

SM 1532

This is a small worm driven motor gearbox unit powered by the new 1532 SM motor. It is available in 25:1, 30:1 and 40:1 single reduction gearbox ratio’s. The SM is a 5-pole motor with approximately 2.9 watts of power it is 15mm wide and 32mm long with shafts at both end. It has a 10000rpm running speed with 8000rpm working speed. See prices below and photo a bottom of page.

Mashima 1833

This gearbox unit is powered by the Mashima 1833 motor and is suitable for medium and smaller locomotives. The 40:1 gearbox ratio is particularly suitable for shunting and slow speed operation. Single or double reduction gearboxes are available and both the motor and gearbox can be purchased separately, if required. A 22.0 mm diameter flywheel is an optional extra on these units.
