High Efficiency Asynchronous Explosion-Proof Motor

YB2 explosion-proof asynchronous AC 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 arcs, sparks 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.

Feature of Product
YB2 series asynchronous explosion-proof 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.
