A brand new 6v dc high-torque can-style motor, as featured in our Lima and Hornby upgrade kits. With the correct wiring and components, these can be used on DC and DCC layouts.
At 10mm thick, this motor is a slimline version of the more common 12mm motor and will fit most co-co diesel and 0-6-0 models. This motor negates the need to cut down the 12mm version to accommodate the middle wheel on a co-co bogie.
Rated Voltage: 6Vdc
Rated Current: 0.03A
Mounting Screw Hole Diameter: 1mm/0.04″
Shaft Size: 2 x 6.5mm/ 0.08″ x 0.25″(D*L)
Body Size: 23.9 x 10mm/ 0.9″ x 0.4″ (D*H)
Cable Length: 6cm/2.4″
Please note: Unless you are buying this motor as a replacement for one provided in our conversion kits, you will also require a replacement drive gear and other materials to complete a conversion.
This motor will fit most OO gauge Lima and Hornby Co-Co and tender-drive ringfield models. However, these manufacturers have produced a wide range of ringfield motors and some configurations may be more tricky to covert than others.
On that basis, we strongly do encourage customers to discuss their requirements and proposals with us beforehand, so we can help to identify any potential issues or important considerations/precautions.
One Hornby ringfield variant that can prove particularly tricky to convert is a Co-Co/tender-drive motor that features left and right track pickups on the motor bogie and has a bogie that is live with the right-hand track voltage (normally the red wire). Some more recent HST power cars use this variant, but there may be others as well.
With these Co-Co/tender-drive models, it is necessary to ensure that:
- The body of the motor makes no contact with any wheels (which may not always be possible) or is isolated from them using tape (which may have a limited lifespan), and/or
- The motor is fully isolated from the bogie using glue around the sides and a thin insulator – e.g. layers of Kapton tape or heat-resistant plastic – placed between the face of the motor and the metal work of the bogies against which it sits.
Whatever model you are converting, please always use a multi-meter to check for short circuits before applying power to a converted locomotive or any decoder. A short could destroy a decoder instantly and also damage the replacement motor.
1. Our replacement motors are low-noise DC motors designed for CD/DVD drives. The output from a DCC decoder or a DC controller can exceed their voltage rating depending on how hard hard the loco is being worked. Whilst our own tests (and those of many others before us) show that these motors are capable of handling voltages higher than their rating, in order to avoid motor burn-out, prolong motor life and achieve prototypical speeds, we recommend:
★ For DC/Analogue use, speeds are kept low manually via the controller and a diode* voltage dropper should be considered in order to reduce voltage going to the motor (as outlined in the instructions);
★ For DCC use, speeds are kept low manually via the controller, decoders should have their CV5 value reduced (if available) and, particularly where CV5 adjustment is not available, a diode* voltage dropper should be considered in order to reduce voltage going to the motor (as outlined in the instructions).
2. With all CD-style motor conversions, it is good practice to: i) maintain very high speeds for relatively short periods only, ii) keep running on steep inclines to a minimum, iii) avoid coupled up with excessively long rakes of coaches/wagons, and iv) where less robust 10mm motors are fitted, resist the temptation to fit additional weight to the loco.
3. It is recommended that locomotives fitted with our 3D printed adaptor kits are not run for more than an hour continuously; this is to prevent the motor temperature from exceeding the glass transition temperature of the plastic.
4. We recommend that locomotives fitted with can-style CD motors are:
★ Not run without a DCC decoder as ‘Locomotive 0’ on a DCC model railway layout (this is will lead to over-heating and rapidly ruin the motor), and
★ Not placed on the tracks whilst a high frequency track cleaner (such as the Gaugemaster HF-1/HF-2) is in operation. There have been some reports that the frequency can damage the motors, although it is not something that we have tested.
We can accept no liability or responsibility for any damage or injury occurring from the installation and use of our motor replacement kits. Installation requires modifications and the use of tools, some of which have the potential to damage you and/or you models, as well as other components and equipment. Users must not commence work unless they are confident that they have the skills and experience necessary to complete it successfully, and install these kits and undertake work to their models at their own risk.
