Recerse Polarity Centrifugal Fan 310 Backward Curved 230V 2350 Medical Ventilation

EC stands for Electronically Commutated, and it combines AC and DC voltages bringing the best of both worlds.

The motor runs on a DC voltage, but with a single phase 230VAC or three phase 400VAC supply. The motor incorporates voltage transformation within the motor.

The non-rotating part of the motor (stator) is extended to make room for an electronic PCBoard which includes power transformation AC to DC, as well as the controls.

EC centrifugal fans with backward-curved blades are used primarily for intake suction. Since most of the pressure build-up takes place in the impeller, there is generally no need for a scroll housing. The centrifugal fans have very good hydraulic efficiency and are ideally suited for high pressures. The centrifugal fans are used in applications such as central air conditioning units or building ventilation systems.

EC centrifugal fans with forward curved blades always require a spiral housing. Their characteristic features are a low noise level, relatively small air flow with a high increase in static pressure, and space-saving application. Depending on aerodynamic and geometric requirements, the impellers are arranged in single-inlet or dual-inlet configurations.

An EC motor (Electronically Commutated) is a brushless, direct current, external rotor type of motor. In commutation electronics, an AC voltage is changed into a direct voltage by a commutator.

The motor position is dependent upon voltage supplied via an inverter module (similar to the principle of a frequency inverter).

The EC commutation electronics are different from a frequency inverter in that they decide how the motor phases in the stator are supplied with current (commutation) depending on position, rotation direction and default.
