Electric motor Foxy C2209/30

Product detailed description

FOXY C2209/30 is a miniature brushless motor designed for driving small models with a flight weight of up to 450 g, powered by a two-cell or three-cell Li-Pol battery. It can successfully power small rubber-powered models with a wingspan of approximately 800-1200 mm, and is also excellent for park flyers of a similar wingspan. The motor is designed for both front and rear mounting.

Foxy motor designation system: CxxYY/zz

Application: *Glider up to 450 g, Trainer up to 450 g, Acrobat up to 400 g, 3D up to 330 g

*) In the table, a glider is understood as a thermal glider, for slope gliders and "hotliners" of a given flight weight, it is necessary to choose an engine as for aerobatic models, or even more powerful.

The "AC" electric motor commonly referred to by modelers is actually a misnomer, because it does not use alternating current, as we have at home in the 230V network. A more correct designation should be a DC brushless electric motor with electronic commutation. They are often referred to as BL DC motors. (from the English BrushLess - carbon-free...).

A classic DC commutator electric motor is very reliable, but its weakness is the use of commutation, which occurs by sliding contact between the brushes - carbons and the commutator on the rotor. It wears out and with poor maintenance or overloading, the life of the motor is significantly shortened. With electronic commutation, this problem disappears. The design of a brushless electric motor is basically reversed, the rotating parts are replaced. The BL DC motor has a fixed stator winding and rotates an exciter consisting mostly of permanent magnets. It is not enough to simply supply voltage to such an electric motor, a control unit is needed that switches the individual stator windings (replacing the commutator). The information from the feedback is processed by a microprocessor that also controls other activities so that the motor works properly. In model making, such an electric motor is controlled by an electronic speed controller (ESC), in which various values ​​​​of the necessary functionality of the electric motor can usually be set and programmed (direction of rotation, start-up, brake, etc.)

Electric motors currently use modern magnets that have significantly stronger magnetic properties. So even with a smaller and lighter design, they provide much higher power than classic commutator motors. Most of these motors are also referred to as "Outrunner", in a classic arrangement with a rotating casing. They have found use in RC models of airplanes, helicopters, drones. In car and boat models (but also aircraft models), these motors are used hidden in the outer casing, they look similar to commutator motors, but have three power wires. They are referred to as "Inrunner".

When combining individual "AC" motors with controllers, it is good to maintain a certain compatibility, not every motor works with any controller. It is advisable to follow the manufacturer's recommendations and it is ideal to use the motor and controller of the same brand and model series. This guarantees compatibility and trouble-free operation. Motors are divided mostly according to size and use and have a recommended operating power supply range, which must be combined with the corresponding power-built controller. For beginners, the choice is made easier by the option to buy a set of motor + controller, which are in the ideal combination. These sets are usually referred to as "Combo Set".

The installation of an Outrunner type motor can be of two types. Either classic, when it is mounted on the motor bulkhead behind the stator and the propeller (or other output) is mounted on the shaft in a classic way, or the so-called inverted assembly (also called the necessary parts for mounting the motor), when the motor is mounted in an inverted position and a special carrier is attached to the rotor, on which the propeller (or other output) is mounted. The assembly depends on the model design.

These electric motors currently represent the cutting edge in the field of electric drives and, with their properties, have almost completely replaced classic commutator electric motors in some industries (e.g. aircraft modeling).
