How to Choose Electric Motors for Model Engines
Model engine hobbies are a fun way to learn more about the way electric motors and heavy machinery work in the real world and can be enjoyed by enthusiasts of all ages. These hobbies involve sourcing and working with the miniaturised materials to build models of cars, trains, helicopters, air-planes and boats. Engines are the essential model parts that bring these miniature machines to life.
It is therefore very important to choose the right electric motor for your purpose, and to learn the basics of electric motor assembly if you intend on building a model boat or car. There are various DIY guides available for hobbyists on the internet and in model construction shops. Depending on your level of expertise, you may purchase an easy to assemble kit that you can use with your children as a fun learning exercise, or for a more in depth experience you may want to start from scratch and find exactly the right electric motor to build the engine of your choice.
In order to choose the right circuit system for your model engine, it is necessary to learn a little about the way heavy machinery works and they way in which they are classified according to power and capabilities. As a starting guide: the power level of a circuit system is measured in Watts, and is equal to the Voltage (V) multiplied by the Current (C). To measure the power of an electric motor in a model air-plane or something similar, you will need a watt meter, a device that measures the power input to the electric motor.
After working with model trains or helicopters for some time you will probably find that you develop a preference for a certain brand or type of motor for you model engines. Many companies produce parts specifically for use by hobbyists and have a focus on delivering minute sized electric motors with the high level of precision, efficiency and power necessary for competition level hobbyists.
One of the most important steps in selecting the right part for your hobby model engine is determining the load requirements of your machine, which is equal to torque and speed versus time. You will also need to consider other factors such as how much you are willing to spend on your model engine, how much power is available for the model vehicle, and what your specific goals are. If you are building a model car, for example, your sole focus could be on speed, whereas with a model aircraft you are more likely to be looking for an electric motor that can provide agility and fast response times.
