Fan Coil Units with BLDC Technology - Customers | Daikin
www.daikin.amWhat is BLDC technology? Brushless Direct Current technology or BLDC motors are also known as Electronically Commutated (EC) motors and consist of a motor combined with an inverter. The BLDC motor has a rotor that is a permanent magnet, the magnetic field of which interacts with the rotating magnetic field produced by the stator windings.

cdn.intechopen.comA BLDC motor is composed of the motor, controller and position sensor. In the BLDC motor, the electromagnets do not move; instead, the permanent magnets rotate and the armature remains static. The rotor magnetic steel is radially placed, and the permanent magnets (generally Neodymium-iron-boron: NdFeB) are installed on the surface. The
