What is the difference between them?
First, whether the motor is equipped with a common brush-commutator, the commutation of the brushed DC motor has been achieved by the contact of the graphite brush with the ring-shaped commutator mounted on the rotor. The brushless DC motor feedbacks the rotor position to the control circuit through the Hall sensor, so that it can know the exact time of the motor phase commutation.
Intelligent pendulum brake motor and brushless motor drive principle different brush motor: the periphery is a magnet, the rotor is surrounded by multiple sets of coils; through a direct current, so that the rotor winding produces a driving magnetic field, in the brush commutator The mechanical structure acts to change the magnetic field of the winding to drive the rotation of the motor.
Brushless motor: The internal rotation is a permanent strong magnet, and the peripheral stator has a fixed winding. By loading different sizes and currents in different directions, the winding produces different magnetic fields acting on the stator, so that the motor rotates at different speeds and directions.
The advantages and disadvantages of the intelligent swing gate brush motor and brushless motor have the advantages of the brush motor: low cost and simple structure; the speed control is relatively simple, and only the voltage can be controlled. The disadvantage is that the mechanical friction of brush-commutator will produce some electric sparks. It can not be used in some special flammable and explosive situations. The friction will produce certain noise and electromagnetic interference; the wear of the commutator and the loss of current; make the motor The life expectancy is short, and it requires frequent maintenance.
The advantages of intelligent pendulum brushless motor: no mechanical friction, small running sound, long life (more than several times to more than ten times of brushed motor), can achieve higher rotation speed, higher power conversion efficiency, more energy-saving Under the condition of use, generally no maintenance is required. The electronic commutation facilitates the control of the rotation direction and rotation speed of the motor, low-speed torque, precision of rotation speed, and better operation efficiency. However, the price is high and the controller's requirements are high.
Beijing Ximo Luo smart swing gate is the brushless motor used, and the smart swing gate in the case runs smoothly and is comfortable. For example: 322DS intelligent swing gate used in the A5 floor of Beijing 58 city headquarters, and 322ES intelligent swing gate installed by Beijing Insurance Supervision Committee. 
If intelligent swing gates are to be installed in office buildings, office buildings, scenic spots, factory sites, etc., first we need to understand the difference between intelligent brushless motors and brushless motors.
