YBX4 series hazardous area motor have a wide range of applications, including petrochemicals, coal mines, underground mines, oil tankers, pharmaceuticals, aerospace, rail transportation, ships, and other fields.
Common explosion-proof types of low-voltage explosion-proof motors include explosion-proof motors, increased safety motors, positive pressure motors, spark free motors, and dust explosion-proof motors.
● Explosion proof motors use explosion-proof enclosures to separate electrical components that may generate sparks, arcs, and hazardous temperatures from the surrounding explosive gas mixture, preventing sparks or arcs from igniting the mixture.
● Measures have been taken in the design of increased safety motors to improve the safety of electrical equipment and reduce or eliminate external and internal factors that may cause explosions, such as increasing insulation levels and reducing surface temperatures.
● Positive pressure motors prevent explosive gases from entering the equipment by maintaining the internal gas pressure higher than the external environment, thus avoiding the occurrence of explosions.
● Non sparking motors are designed and material selected to ensure that sparks are not generated under normal operation or fault conditions, making them suitable for spark sensitive environments.
● Dust explosion-proof motors are specifically designed to prevent dust accumulation and ignition, and are suitable for places with dust explosion risks.
These explosion-proof hazardous area motors are selected according to different usage environments and safety requirements to ensure safe operation in flammable and explosive places

Explosion proof motors are classified into different temperature groups based on their usage conditions and environmental temperature requirements. The common temperature groups for explosion-proof motors are T1, T2, T3, T4, T5, and T6.
T1 group: Suitable for places with a maximum surface temperature not exceeding 450 ℃.
T2 group: Suitable for places with a maximum surface temperature not exceeding 300 ℃.
T3 group: suitable for places with a maximum surface temperature not exceeding 200 ℃.
T4 group: Suitable for places with a maximum surface temperature not exceeding 135 ℃.
T5 group: Suitable for places with a maximum surface temperature not exceeding 100 ℃.
T6 group: suitable for places with a maximum surface temperature not exceeding 85 ℃.
Based on actual usage and temperature requirements, selecting the appropriate explosion-proof motor temperature group can ensure that the motor can operate safely and reliably in harsh environments.

| Exd explosion-proof junction box belongs to the pressure explosion explosion-proof level and is suitable for places where explosive gases exist. This type of junction box, through special design and structure, can withstand the pressure generated by internal explosions and prevent the spread of explosion flames outward. | Explosion proof metal gland is specifically used for explosion-proof equipment such as explosion-proof distribution boxes and explosion-proof instrument boxes of YBX4 series hazardous area motor. Their most important function is explosion-proof and isolation, so they are widely used in various places that require electrical safety and explosion-proof, such as petroleum and chemical industries. | Temperature sensors play an important role in motor monitoring. It can monitor the temperature of YBX4 series hazardous area motor in real time and detect motor overheating problems in a timely manner. Meanwhile, the temperature sensor can also detect the ambient temperature, providing more reliable data support for the normal operation of the motor. | Generally speaking, the service life of imported bearings may be longer than that of domestic bearings, reaching 2 to 5 years, while domestic bearings are generally between 2 to 4 years. However, the actual service life of bearings is affected by various factors, such as usage environment, load capacity, and structure. |
