Explosion-proof Principle:

Explosion-proof "Ex d" motors are a form of explosion-proof motor. The principle is to place components that may generate sparks, arcs, or dangerously high temperatures in a flameproof enclosure during the regular operation of the equipment. The explosion-proof casing can withstand internal pressure without damage and can ensure that when the internal flame gas propagates through the gap, the energy is reduced. It is not enough to detonate the gas outside the casing.

YBX3 Series Explosion-proof Three-Phase Motor Features:

YBX3 series explosion-proof motor has the advantages of energy saving, large temperature rise margin, long life, good performance, low vibration, advanced explosion-proof structure, excellent starting performance, beautiful appearance, high reliability, and no electric spark is generated during operation. The main junction box of the motor is located at the top, and the temperature measurement, bearing temperature measurement, and heater can also be selected according to the user's needs.

YBX3 Series Flameproof Three-Phase Motor Applications and Advantages:

YBX3 series motor is suitable for equipment where flammable gas containing specific components or explosive mixtures of steam and air exist. It's mainly used in the petroleum and chemical industry, also widely applied in textile, metallurgy, city gas, transportation, grain and oil processing, paper, medicine, and other industries. The efficiency index conforms to the grade 2 specified in GB18613-2012 Minimum Allowable Values of Energy Efficiency and Energy Efficiency Grades for Small and Medium Three-phase Asynchronous Motors.

The remarkable characteristics of this series motor are high efficiency and energy conservation, large temperature rise margin, long lifetime, slight vibration, low noise, and high reliability. And auxiliary equipment such as winding temperature sensor, bearing temperature sensor, temperature transmitter, and heater can be installed according to user needs.

The Difference Between Explosion Proof Motor YB2/YB3 And YBX3:

The YB2 series flameproof three-phase asynchronous motor is an updated product of the YB series. It is the essential series of explosion-proof motors. This series of motors have the characteristics of small size, lightweight, beautiful appearance, safe and reliable operation, long service life, good performance, convenient installation, use, and maintenance.

The YB3 series is in YB, YB2 series motor based on the combination of the current domestic and foreign electromagnetic structure, technology, material, and other aspects of the new technology and developed new products with high efficiency and energy saving, temperature rise degree, long service life, good performance, low noise, flameproof advanced structure, high reliability, convenient use, and maintenance, etc.

YBX3 series is based on the original YB3 series motor, according to the 2-level energy efficiency standard in GB18613-2012, to standardize the design of the new motor. These explosion-proof motors' power levels and mounting dimensions conform to the IEC standard and are the same as those of the YB and YB2 series motors.
