Mainly applications: HVACR ventilation systems, air purifier, air cleaner, AHU, FCU, etc
DC motors are around 30% more efficient than AC motors because the secondary magnetic field comes from permanent magnets rather than copper windings. An AC motor consumes additional energy solely to create a magnetic field by inducing a current in the rotor. But this is only half the story. The use of modern electronics in controlling the motor has opened up many other possibilities which contribute to using less power.
Construction:
Cowls are of galvanised steel construction.
Impellers are backward-curved centrifugal design and are of high performance composite material.
