Aeromodelling motors are the specialized motors used to power model aircraft, often referred to as drones or remote-controlled airplanes. These motors are designed to be lightweight yet powerful, providing the necessary thrust for flight. Here are the key types of motors commonly used in aeromodelling:
- Electric Motors:
- Brushed Motors: These are traditional DC motors with brushes and a commutator. They are simple, cost-effective, and can be used for smaller model aircraft.
- Brushless Motors: These are more efficient and durable than brushed motors. They have a higher power-to-weight ratio and are widely used in aeromodelling due to their performance and reliability.
- Internal Combustion Engines:
- Glow Engines: Also known as nitro engines, these are small internal combustion engines that use a glow plug for ignition. They are popular for powering larger model aircraft and provide a realistic engine sound.
- Gasoline Engines: Larger models, including scale airplanes, often use gasoline engines. These engines are more fuel-efficient and can provide considerable power for heavier aircraft.
- Turbine Engines:
- Jet Turbines: Advanced aeromodellers use miniature jet turbines to power high-performance model jets. These turbines are complex and replicate the operation of real jet engines, producing impressive thrust and speed.
Factors to consider when choosing an aeromodelling motor include the size and weight of the model, desired flight characteristics (such as speed or endurance), and the availability of suitable power sources (batteries, fuel). Electric motors have become increasingly popular due to advancements in battery technology (such as lithium polymer batteries) and the convenience of electric power systems for smaller and mid-sized models.
When selecting a motor for an aeromodelling project, it’s important to consider the motor’s specifications including its maximum power output, efficiency, weight, and compatibility with the aircraft’s design and intended use. The motor must also be matched with an appropriate propeller and battery (or fuel system) to achieve optimal performance and flight duration.
