A brushless electric motor or brushless motor is un electric motor not used brushes to change the polarity of the rotor.

Electric motors used to have either a slip ring commutator or a pair of slip rings. These systems, which produce friction, reduce performance, give off heat and noise, require a lot of maintenance and can produce carbon particles that stain the engine with a dust that can also be conductive.

The first brushless motors were the de  motors.alternating current async. Nowadays, thanks to electronics, they are very advantageous, since they are cheaper to manufacture, weigh less and require less maintenance, but their control is much more complex. This complexity has been virtually eliminated with ESC electronic speed controllers.

Other brushless motors, which only work with direct current, are those used in small low-power electrical devices, such as CD-ROM drives, computer fans, cassette players, etc. Its mechanism is based on replacing the mechanical commutation (change of polarity) with another electronic one without contact. In this case, the loop is only driven when the pole is correct, and when it is not, the electronic system cuts off the current supply. To detect the position of the rotor turn, detection of a magnetic field is used. This electronic system, in addition, can report the speed of rotation, or if it is stopped, and even cut the current if it stops so that it does not burn. They have the disadvantage that they do not rotate backwards when changing their polarity (+ and -). To make the change, two conductors of the electronic system should cross.

A somewhat similar system, to avoid this friction in the rings, is used in los alternators. In this case, the use of slip rings is not avoided, but rather the use of a more robust one, which would slow down the motor a lot, is avoided. Currently, alternators have the inducing magnetic field in the rotor, which induces the magnetic field to the stator, which in turn is induced.

As the magnetic field of the inductor needs much less current than the one that will be generated in the armature, rings with a lower friction are needed. This configuration is used from small car alternators to power plant generators with powers of the order of megawatt.

Advantages, disadvantages and applications

The motors have the characteristic that they do not use brushes in the commutation for the transfer of energy; in this case, the switching is done electronically. This property eliminates the great problem that conventional electric motors with brushes have, which produce friction, reduce performance, give off heat, are noisy and require periodic replacement and, therefore, greater maintenance.

Brushless motors have many advantages over brushed DC motors and over induction motors. Some of these are:

  • higher speed-torque ratio

  • higher dynamic response

  • greater efficiency

  • longer shelf life

  • less noise

  • increased speed range

ROGER motors for door automation.

ROGER 600Kg BH30/600 HS Brushless motor kit for sliding gates.

Extremely strong motor, with a lot of torque but at the same time extremely small and compact, thanks to its special windings of concentrated coils and powered by a three-phase sinusoidal system.

The silence or practically non-existent noise of the BRUSHLESS motor during all its movements is very surprising.

The BRUSHLESS digital controller, which works at low voltage 24V/36V DC, allows the automation to be controlled 100% in digital mode. Thanks to an operation based entirely on a DSP microcontroller, the stroke and all the movements of the automation can be programmed and customized in a simple, exact and elegant way.

The ROGER H30/640 HS Motor with BRUSHLESS digital technology produces perfect, elegant movements with constant force and torque at each of its points with maximum safety and always with the possibility of varying its speed, directing perfect slowing movements and acceleration.

Thanks to digital technology we can detect an obstacle and reverse the motor instantly, easily defining the torque of the motor, the sensitivity, the time and the reversal stroke. Always respecting the maximum security conditions.

A motor that can work at low voltage, with super-intensive use, operating in environments with very difficult climatic conditions and always maintaining extremely low consumption.
