All current models are fitted with electric motors or internal combustion engines.
Models with electric motors, in turn, are divided into two types: the collector and brushless motors.
Electric Collector engine - is the heart of a large number of radio-controlled models, in particular - the economy. The principle of operation of the mechanism is simple enough - currents flow in opposite directions in the two sites combined motor - rotor and stator, whereby there are electromagnetic fields that move the movable part of the engine - the rotor.
The simplicity of this mechanism makes it quite cheap to produce and easy to use, making these engines are often used in radio-controlled models. In most cases, the collector engines are used in radio-controlled entry-level model.
Benefits collector engines for model aircraft :
Easy to repair.
Disadvantages collector engines for model aircraft :
rapid wear of brushes. This leads to the need for frequent repairs of these machines in comparison with models of the brushless system;
low efficiency (60%) compared with brushless motors.
Collector engines on the remote machines are powered by direct current network or from ordinary batteries.
Brushless models are more serious. They do not honk, they can run even in covered areas.
In brushless motors for model aircraft is moving part of the stator and the rotor with a three-phase winding - fixed. Such motors are compared with the collector are more reliable, which is achieved by the absence of the brush mechanism.
Benefits brushless motors for model aircraft :
high engine efficiency - up to 92%;
High maximum speed;
wear-resistant thanks to the closed type motor;
good protection against dirt, dust and moisture.
Disadvantages brushless motors for model aircraft :
complex motor repair in case of breakage.
