Welcome to our collection of
Model Engine kits.
Early electric engines look like steam engines because their inventors copied steam engine design and practice. Over time other inventive designs were developed and our range of Model Engine kits reflect those exciting times.
Please watch the short 3 minute video introduction
The First Electric Engines
Many early electric engines followed steam engine design but replaced the steam with electromagnets. These were reciprocating engines and used connecting rods, beams and flywheels that had to be constantly accelerated.
These early reciprocating engines were quickly followed by revolving armature designs of which Paul Gustave Froment’s was the first in 1844. These were much more efficient and a variety of different and increasingly sophisticated designs emerged.
By the close of the Victorian era the flywheel had become a rotor and the age of steam was giving way to the age of electricity.
Model Engine kits from the Old Model Company
The model electric engine kits manufactured by the Old Model Company reflect those exciting times and every effort has gone into ensuring that each kit is historically correct and as close as possible to the original design.
Great attention to detail has been taken to ensure that all the parts are made in the style of the period. The brass pillars, finials and terminal connectors are typical of the times as are the elegant flywheels and fully functioning on/off switches.
The OMC range of engines are supplied in kit form and can be assembled using ordinary hand tools. No machining or soldering is necessary.
Each kit includes a fully illustrated instruction manual that is easy to follow. The parts are supplied in numbered packets that correspond to numbered instructions in the manual.
Even the packaging that the kit comes in is easily converted to an assembly jig that holds the model securely whilst connecting the wiring underneath.
These model engines work on safe and low DC voltages, typically 4.5 to 6 volts.
Clicking on the picture of each model will take you to a video presentation of that engine and to a complete specification.
Overview of our Model Engine kits.
OMC-1 Rocking engine. A reciprocating engine with two power pulses per rotation. The armature rocks too and fro on the coil rods and this motion is transferred via an arm, connecting rod and crank to a timing shaft. Timing is achieved with two timing blades acting on a cam fitted to the shaft. Power is taken off via a pulley. A flywheel ensures momentum.
OMC-2 Beam Engine. Two banks of coils are energized in turn causing an armature plate to rock. This movement is transmitted via connecting rods, a beam and crank to a timing shaft and power take off pulley. Two sets of timing points are activated by cams and this arrangement is fully adjustable. A flywheel ensures momentum.
OMC-3 Froment Engine. Four armatures are fixed directly to a flywheel immediately above an electro magnet. This magnet is energized as each armature approaches and turns off as it passes. Timing is cam operated via the shaft and is fully adjustable. Power is taken off via a pulley.
OMC-4, Series Two, Rotative Engine. An example of an Edwardian engine and the early use of a rotor instead of a flywheel. The armatures are placed within the rotor and pass between the coil rods for greater efficiency. With six power pulses per rotation, the timing is achieved via a six sided cam and is fully adjustable. Mounted on a classic hardwood base and fitted with a fully working on/off switch.
OMC-5, Series Two, Rotative Engine. With two banks of coils, one on either side of the rotor, this more powerful engine operates with 12 power pulses per rotation. Two sets of cams and timing blades, operating on a common shaft, are provided and can be individually adjusted. Mounted on a classic hardwood base and fitted with a fully functioning on/off switch.
