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.

Purchasing Guide

Conduct environmental analysis: Understand the nature, level, and temperature requirements of the explosion.

Determine motor type: Select the corresponding explosion type (gas, dust, or coexistence) based on environmental classification.

 Choose explosion level: Select based on the nature and level of the explosion present in the actual environment.

 Consider temperature rating: Ensure that the temperature rating of the motor meets environmental requirements.

 Refer to product certification: Ensure that the selected motor meets the safety standards and certification requirements of the relevant country or region.

 Pay attention to the performance of YBX4 series non sparking motor: consider the power, speed, insulation level, and protection level of the motor.

These explosion-proof types are selected according to different usage environments and safety requirements to ensure safe operation in flammable and explosive places.

The maintenance of rolling bearings is the key to ensuring their long-term effective operation. Choose lubricants correctly, considering environmental conditions, temperature, speed, and load, and follow the manufacturer's recommendations.Regularly replenish or replace lubricants to maintain the good operating condition of bearings. ‌‌	The main features of IP68 waterproof gland include waterproof, dustproof, salt resistant, acid and alkali resistant, alcohol, oil, ester and other general solvents. They also have excellent sealing performance and can achieve an IP68 protection level by tightening the nut with a sealing ring within the specified range of the checkpoint. YBX4 series non sparking motor with IP68 gland will have high protection while producing.‌‌‌‌	RTD is a temperature sensor that works based on the resistance value changing with temperature. This type of sensor not only provides good accuracy, but also has excellent stability and repeatability, which is crucial for protecting YBX4 series non sparking motor from overheating damage. ‌	During transportation, YBX4 series non sparking motor should avoid damage from external forces such as impact, compression, and vibration. This requires packaging materials with certain mechanical strength and corrosion resistance, such as wooden boxes, metal boxes, or plastic films. Choosing suitable packaging materials is crucial for protecting the motor.
