Product catalog summary

About Blauberg Group
Blauberg Group is a manufacturer of energy-efficient ventilation equipment, including domestic and industrial fans, and air handling units. The company focuses on innovative technology, contemporary design, and traditional German quality. Blauberg Motoren, a division of the group, produces motors and fans with EC and AC technology, with facilities in Germany and Ukraine.

Fan Motors
The catalogue describes two types of motors: synchronous and asynchronous. Asynchronous motors are favored for their simple design and ease of operation, featuring a stator and rotor. They maintain constant speed under various loads, resist overloads, and start easily. EC motors are high-efficiency synchronous motors with electronic commutation, offering reduced energy demand and high performance.

Designation Key
A designation key is provided to identify fan models based on voltage, motor type, impeller modification, and casing type, aiding in selecting the appropriate fan for specific applications.

Backward Curved AC Centrifugal Fans
These fans feature backward-curved impellers made from PA plastic with glass fiber, offering continuous operation, ball bearings, and self-resetting motor protection. Technical data includes nominal voltage, frequency, speed, power input, and sound pressure levels.

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 exceeding...

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 %. These...
