Fan coil units - Daikin
www.daikin.ammotors 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. This is combined with an electronic commutation system that is made up of an

www.rses.orgThe constant-airflow (variable-speed) ECM was introduced in 1987 by GE (rebranded Genteq™ in 2009). It was the first and only indoor blower ECM until the introduction of the constant-torque ECM in 2006. The term “variable-speed motor” was coined in the late 1980s. By function it is a “constant-airflow motor.”
