Product Description

YB2 ac explosion-proof asynchronous motor is a kind of motor that can be used in flammable and explosive places, and does not generate electric spark during operation. It is a motor structure that does not generate arcing, sparking or dangerous high temperatures under normal operating conditions, and then takes some mechanical, electrical and thermal protection measures to further avoid arcing, sparking or under normal or approved overload conditions. The danger of high temperatures ensures the safety of explosion protection.
YB2 ac explosion-proof asynchronous motors are mainly used in coal, oil and gas, petrochemical and chemical industries. In addition, it is widely used in textile, metallurgy, city gas, transportation, grain and oil processing, paper, medicine and other departments. Explosion-proof motors are used as the main power equipment and are commonly used to drive pumps, fans, compressors and other transmission machinery.

YB2 series fully enclosed self-fan cold squirrel-type explosion-proof three-phase asynchronous motor, which has the characteristics of high efficiency, energy saving, large starting torque, good performance, low noise, low vibration, high reliability and convenient use and maintenance.
(1) The correspondence between power class, installation size and speed is consistent with DIN42673. Considering the compatibility with the YB series and the interchangeability of the Y2 series, the necessary adjustments are made, which is more effective and applicable.
(2) The whole series adopts Class F insulation, and the temperature rise is assessed according to Class B.
(3) The noise limit is lower than that of the YB series, which is close to the Y-class noise of the YB series, and the vibration limit is equivalent to the YB series.
(4) The enclosure protection level is increased to IP55.
(5) The whole series uses low-noise deep groove ball bearings, and the center of the machine base is higher than 180mm.
(6) There are two types of motor heat sinks: parallel horizontal distribution and radiation distribution, which are mainly parallel horizontal distribution.


Main process flow of the motor
Motor stator: casing processing → punching press → iron core seating → coil making → weaving → dipping paint drying
Electronic rotor: blank shaft processing → iron core press installation → iron core cast aluminum → rotor string shaft → weave → dipping paint drying → dynamic balance
Motor assembly: stator rotor assembly → machine test → motor appearance coloring → packaging storage
