Brushless DC motor – why has it become the \”darling\” of electric doors?

In the past two years, the field of pedestrian gates has developed rapidly, and motor applications have evolved from brushed Motors gradually transitioned to brushless motors and then to brushless DC motors. Have you ever wondered why pedestrian walkway doors favor brushless DC motors? What are the unique advantages of brushless DC motors for pedestrian advertising doors?

DC brushless The motor has significant advantages, its control is simple and the technology is mature, and it has excellent control characteristics that are difficult to match with the AC motor. In the early days of the development of electric vehicles, DC motors were widely used, and some electric vehicles are still driven by DC motors. However, DC motors have brushes and mechanical commutators, which limit the motor\’s overload capability and do not perform well at speed increases. If it runs for a long time, the brushes and commutator need to be maintained and replaced, the rotor will also suffer losses, and heat dissipation will be difficult, which greatly limits the torque-to-mass ratio of the motor. For this reason, newly developed electric vehicles basically no longer use DC motors.

The brushless motor can be called a high-performance \”artifact\”. Its external characteristics are similar to a DC reducer, and it has a brushless mechanical contact structure and a permanent magnet rotor, so there is no excitation loss. Its armature winding is located on the outer stator, allowing easy heat dissipation. Brushless motors do not produce commutation sparks, have no radio interference, have long service life, reliable operation, simple maintenance, and their speed is not limited by mechanical commutation. If equipped with air and magnetic bearings, it can even rotate hundreds of thousands of times per minute. with other motorsCompared with other systems, brushless motors have high energy density and high efficiency, and their application prospects in electric doors and other fields are bright.
