Motors & Gearboxes

Note: All motor/gearbox units are fitted with M3 grubscrews an M3 Allen key can be provided.

JH

The JH is designed for medium to large sized locomotives, but can be used in large locomotives where space is at a premium.

The motor can be purchased separately or combined with a double reduction gearboxes. 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 double reduction gearbox with this motor is available in two ratios; 25:1 & 33:1 – the lower the number the faster the drive axle revolves. JH double reduction units are also available with 1/4” axle for Gauge 1.

The JH motor has a  2.3mm shaft, a no load speed of 8,200 rpm (+/- 10%), and a stalled torque 409 gram cm. For JH motor/gearbox dimensions see the MSC Price List.

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 and 25:1, 33:1 and 50:1 double 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 with similar power to the Mashima 1833 motor. It has a 10000rpm running speed with 8000rpm working speed. If required a 22mm diameter flywheel is an optional extra on these units.

SM 1525

For smaller locomotives a smaller SM motor is available, this is the 1525 (15mm wide and 25mm long). The 1525 motor is available with a 40:1 single reduction gearbox for the same price as the SM 1532 40:1 gearbox unit.

Gearboxes may also be purchased separately. The single reduction gearboxes will also fit the Mashima 1833 motor.
