High-efficiency electric motors that deliver measurable energy savings for our customers
The rated voltage, rated current, power, and speed of explosion-proof motors are the same as those marked on ordinary motors. The difference is that YBX4 series non sparking motor has an explosion-proof mark Ex, which is basically displayed on the main junction box cover. Explosion proof motors use explosion-proof enclosures to separate electrical parts that may generate sparks, arcs, and dangerous temperatures from the surrounding explosive gas mixture. Therefore, in environments where flammable and explosive gases, powders, and water vapor may be generated, reliable and safe explosion-proof motors are definitely the best choice.
Brief Introduction
Explosion proof motors use explosion-proof shells, but these shells are not sealed, and explosive gas mixtures around them can enter the interior of the YBX4 series non sparking motor through the gaps between the joint surfaces of various parts of the shell. When in contact with ignition sources such as sparks, arcs, and dangerous high temperatures inside the casing, an explosion may occur. At this time, the explosion-proof casing of the motor will not be damaged or deformed, and when the explosive flame or hot gas is transmitted through the gap between the joint surfaces, it cannot ignite the surrounding explosive gas mixture.
The main characteristics of explosion-proof non sparking motors are as follows:
● The corresponding relationship between power level, installation size, and speed is consistent with DIN42673, and necessary adjustments have been made to make it more effective and applicable, taking into account the inheritance with YB series and interchangeability with Y2 series.
● The entire series adopts F-level insulation, and the temperature rise is assessed according to B-level.
● The noise limit is lower than that of the YB series, approaching the I-level noise of the YB series, and the vibration limit is comparable to that of the YB series.
● The protection level of the shell has been raised to a minimum of IP55.
● The entire series uses low-noise deep groove ball bearings, and motors with a center height of over 180mm are equipped with oil injection and discharge devices.
● There are two types of motor heat sinks: parallel horizontal distribution and radiation distribution, with parallel horizontal distribution being the main one.
● The main performance indicators have reached the international advanced level in the early 1990s.
