FAN MOTORS THE MOTORS ARE POWERED BY DIRECT OR ALTERNATING CURRENT. A direct current motor is powered by a direct power supply. An alternating current motor is powered by an alternating power supply. Alternating current motors are the most widely used motors because the basic electric grid in the country has alternating power supply. ALTERNATING CURRENT MOTORS HAVE TWO TYPES: Synchronous electric motors are alternating current motors with a rotor that rotates synchronously with a magnetic field. Asynchronous electric motors are alternating current motors with the magnetic field frequency...

EC motors The electric motor with electronic commutation (EC motor) is a highefficient synchronous direct current motor driven by an electronic commutating unit (controller). It has no friction and wearing parts as a collector or brushes, unlike the standard motor. The function of these parts is performed with the maintenance-free electronic circuit of the EC controller. The EC technology is the state-of-the-art method for arrangement of energy saving and high efficient ventilation. The energy demand of EC motors is by 50 % less as compared to standard motors and efficiency reaches 90 %....
