YB2 ac explosion-evidence asynchronous motor is a kind of motor that can be employed in flammable and explosive locations, and does not produce electrical spark during operation. It is a motor structure that does not produce arcing, sparking or hazardous substantial temperatures below normal functioning problems, and then requires some mechanical, electrical and thermal security steps to additional keep away from arcing, sparking or beneath normal or authorized overload problems. The threat of large temperatures assures the basic safety of explosion protection.
YB2 ac explosion-evidence asynchronous motors are mostly used in coal, oil and gas, petrochemical and chemical industries. In addition, it is widely utilised in textile, metallurgy, metropolis fuel, transportation, grain and oil processing, paper, medication and other departments. Explosion-evidence motors are utilized as the primary power gear and are commonly employed to travel pumps, fans, compressors and other transmission equipment.

YB2 sequence completely enclosed self-supporter cold squirrel-kind explosion-evidence 3-phase asynchronous motor, which has the characteristics of substantial efficiency, strength conserving, huge starting torque, very good efficiency, reduced noise, reduced vibration, high reliability and practical use and servicing.
(1) The correspondence among power class, installation size and pace is consistent with DIN42673. Taking into consideration the compatibility with the YB series and the interchangeability of the Y2 collection, the required changes are created, which is much more effective and relevant.
(two) The entire series adopts Class F insulation, and the temperature rise is assessed according to Class B.
(3) The sound limit is lower than that of the YB series, which is close to the Y-course sound of the YB sequence, and the vibration limit is equivalent to the YB collection.
(four) The enclosure defense degree is elevated to IP55.
(5) The complete sequence makes use of reduced-sounds deep groove ball bearings, and the heart of the device base is greater than 180mm.
(six) There are two kinds of motor warmth sinks: parallel horizontal distribution and radiation distribution, which are primarily parallel horizontal distribution.
Major method movement of the motor
Motor stator: casing processing → punching push → iron main seating → coil making → weaving → dipping paint drying
Electronic rotor: blank shaft processing → iron core press set up → iron core forged aluminum → rotor string shaft → weave → dipping paint drying → dynamic balance
Motor assembly: stator rotor assembly → machine examination → motor look coloring → packaging storage
