YB3 Series Explosion Proof Three Phase Induction Motor

YB3 Series Explosion Proof Three Phase Induction Motor

YB3 series explosion proof three-phase induction electric motor is applicable to be used in a place containing explosive mixtures of flammable gas or vapour and air. YB3 ranges of three-phase induction motors are flameproof motors obtained by renewal and generation-changing of YB2 and YB ranges of motors. The performances of the YB3 series explosion proof motor have come up to advanced international standards, providing the petrol and chemical industry with new-generation driving equipment which is safer, more advanced, more reliable, and more efficient. The outputs, mounting dimensions, and their corresponding relationships comply with IEC standards.

Model Analysis of YB3 Series Explosion-proof Motor:

The Meaning of the Explosion-proof Mark of YB3 Motor: ExdⅡBT4Gb

  • Ex: mark (explosion proof)
  • d: Explosion-proof type of electrical equipment (explosion-proof type)
  • IIB: Electrical equipment category level (Class II Class B)
  • T4: Temperature group (T4)
  • Gb: Equipment Protection Level (Gb)

YB3 Explosion-proof Motor Model Representative Meaning: YB3-355M1-4W

  • Y: induction motor
  • B: flameproof type
  • 3: Design serial number, 3 represents three designs
  • 355: The center height of the base (355mm)
  • M: base length (M means middle base)
  • 1:1 iron core length
  • 4: Number of poles (4 poles)
  • W: special environment code (outdoor type)

The Difference Between Explosion-proof Motors and Ordinary Motors:

Ordinary motor refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction.

1. The explosion-proof motor adopts brushless excitation, equipped with a rotating rectifier disk and a static excitation cabinet, and the excitation control system is reliable; the forward polarity slip excitation is accurate without impact; the excitation system has reliable out-of-step protection and strong re-stepping ability; circuit design Reasonable, the discharge resistance does not generate heat during work; the excitation current has a wide adjustment range.

2. Synchronous machine, AC exciter, and rotating rectifier disc are coaxial. The rectifier disk is located between the main motor and the exciter or outside the bearing seat.

3. Meet the requirements of increased-safety explosion-proof motors, adopt a series of reliable measures to prevent sparks, arcs and dangerous high temperatures, and can safely operate in explosion-hazardous areas in Zone 2.

4, the protection level of the explosion-proof motor shell is IP55.

YB3 Series Explosion Proof Motor Characteristic YB3 Series Explosion Proof Motor Characteristic

5. The explosion-proof motor adopts class F insulation, and the temperature rise is assessed according to class B. Ordinary motors cannot meet this requirement.

6. ​​The explosion-proof motor changes the traditional lower water cooling to upper water cooling, that is, the water cooler is placed on the upper part of the motor.

7. An increased-safety moisture-proof heater is installed, which is fixed in the cover at the bottom of the motor for heating and moisture-proof during the shutdown.

8. The end cover of the explosion-proof motor adopts recessed dark bolts, and the slot is 5 times deeper than the ordinary motor (asbestos pad is required as required), mainly to prevent the internal winding from being burned, the spark will not go along the gap Fleeing.

9. For the cooling fan at the end of the explosion-proof motor, in order to prevent the blade from rubbing against the windshield, the outer edge of the wind blade is far away from the wind deflector, and the wind blade is made of plastic.

10. Of course, due to the special structure and material of the explosion-proof motor, the price of the explosion-proof motor will be much more expensive than the ordinary motor.

YB3 Series Explosion Proof Motor Application Field:

The YB3 series explosion proof motor is used as the drive motor of the mechanical equipment in the underground coal mine (non-excavation working face) fixed equipment or factory IIB grade, the temperature group is T1-T4 group of flammable gas or explosive mixture of steam and air. , mainly used in coal mining, petroleum natural, petrochemical and chemical industries. In addition, it is also widely used in textile, metallurgy, city gas, transportation, grain and oil processing, papermaking, medicine and other departments. As the main power equipment, explosion-proof motors are usually used to drive pumps, fans, compressors, conveyors and other transmission machinery.
