Eco-fan is an electric motor of 220 (VAC), 50 (Hz), PMSM type (with ferrite magnet rotor). According to the IRAM 62480:2017 Standard, an Energy Efficiency (EE) Type: A. With an energy consumption lower than 55% of the nominal value of the motor. Value calculated for one (1) hour per day at maximum power: 25 (Watts). 59% active electrical energy saving. The physical unit of physical measurement (MKS) shows an energy consumption of 15 kWh/month (kiloWatt-hours/month), at maximum speed, without losing or lowering revolutions per minute (close to 3000 RPM), which is the synchronous speed of the two (2) pole rotor with the frequency of the alternating current (50 Hertz). PMSM type motors (like the one used here) provide rotation at a fixed speed in synchronicity with the frequency of the power supply, regardless of the load fluctuation (higher or lower) that produces the resistant torque. The voltage (Volts) and current (Amps) of the current drops when the TRIAC acts; and anyway, the motor runs at a synchronous speed (3000 RPM) with mains frequency (50 Hz).
