Brush-less Hub Motors
With these engines, there is no problem with closing the circuitry through the rotor over brushes, and therefore it is cheaper to maintain and there is no cheating between the rotor and the brush. As a controller dictating the direction of rotation of the motor, it must know where the rotor is in relation to the stator in the stator; there is a Hall sensor or a rotary encoder.
Due to the defects caused by the commutator in recent times, a two-dimensional brushless motor has been developed, which has a permanent magnet on the rotor, while through the wind winds break the current leading to rotation of the rotor. The current passing through the stator windings is controlled by an electronic circuit, the so-called electronic commutator or inverter, which replaces the classic commutator. In order to be able to correctly determine through which electronic commutator will fill the current, and the current to be directed, such a motor must have a rotor position sensor on the basis of which the commutator operates.
Efficient BLDC brushless motor
Stamina despite long-term continuous work
With the use of low-current BLDC motors, heat generation is induced; The increased temperature on the surface of the enclosure can be reduced even in heavy industrial applications, which require long and lasting loads.
More work with one charge of the battery
BLDC motors are more efficient and have better energy production and are specially designed to provide more work with one charge of the battery. The longer life of the battery reduces the cost of battery power tools.
DC motor without brushes
It’s not maintained because there are no brushes. Energy production is more efficient than a DC motor with wipers because there are no losses due to plugs, which allows lower current to reduce heat production and longer operation with one charge of the battery
