CR12 - CR165 50/60Hz CONDENSERS General Description Fan & Motor Assembly CR12 - CR16 Axial flow fan assembly with low noise sickle type blades. CR22 – CR165 Axial flow fan assembly with low noise sickle type blades and bellmouth. All Models The external rotor ac motor allows the use of a low power output, single phase and speed controllable motor to power the fan. -
Page 9: Electronically Commutated (Ec) Fan Motor
Each fan incorporates electronically commutated DC motor control using semi-conductor modules responding to a signal from the Airedale indoor unit. EC motors are DC motors with integrated ac to DC conversion; this gives the flexibility of connecting to ac mains with the efficiency and simple speed control of a DC motor. -
