YB2 Series High Voltage Explosion-Proof Electric Motor

YB2 Series High Voltage Explosion-Proof Electric Motor Description

YB2 series flame-proof three-phase asynchronous motor is the basic flame-proof motor product that is developed by combining current market and domestic flame-proof motor industry, and is also the new generation product of YB series．

YB2 series of motors have the flame-proof performance meeting, the regulations of GB3836．1-2000, Gb3836.2-2000, IEC79-1 and DIN En50014～50020、and use the flame-proof marks of Exd I．Exd II AT4 and Exd II Bt4．thus are applied at the location with explosive gas compound．and the Exd I is applied in the non-excavation working condition and the coal mine with methane or coal dust．the Exd II AT4 and Exd II BT4 are applied in the condition of flame-proof gas compound with Factory II type，Grade A，B and the temperature T1，T2，T3 and T4．Basing on YB2 basic series motor, we may derive it into many kinds of flame-proof motors such as YB2-W outdoor type．YB2-WTH outdoor humid&tropic type etc.

Enclosure protection rating of the motor in this series are generally IP54, cooling method is IC411 the installation IMB3, also be made of different types of protection, cooling, installation methods according to user requirements.

YB2 Series High Voltage Explosion-Proof Electric Motor Features and Application

YB2 series motor has these good features of high efficiency, energy saving, big temperature-rising range,, low noise, small libration, high-grade protection, advanced flame-proof structure, safety& reliability, convenient saving power equipment being applied in the industries of coal, oil, chemical industry etc.

YB2 Series High Voltage Explosion-Proof Electric Motor Construction Features

This series motors are compact structure of the international fashion, frame, end caps and external surfaces of the distribution of cooling ribs, small size, beautiful appearance.

Stator exterior pressure structure, insulation class F stator coil made with insulated copper flat wound coil by wrapping the main insulation and VPI overall Impregnation with high electric strength, mechanical strength and insulation properties. moisture resistance and thermal stability.

Squirrel-cage rotor, high-precision calibration balancing the motor running smoothly, and little vibration.

High-voltage junction box sealing structure, the wiring cavity, leaving the cable connector position. The location of the junction box is generally the right side of the motor.

According to the different power and speed bearing structure selection: H355 ~~ 560-4,6,8 P Rolling H500, ~ 560-2P ​​with sliding bearings. Rolling bearings of the motor bearings at both ends Note oil discharge device set without stopping the machine, and regular replenishment of grease, sliding bearing end cap-type spherical plain bearings, pressure lubrication, oil ring self-lubricating composite lubrication methods (by the user freedom of choice , as no special requirements, compared with pressure lubrication), while taking measures to prevent the shaft current.

According to user needs, the motor can be installed on the bearing temperature measurement devices or instrumentation to monitor the bearing temperature stator temperature measurement devices, instruments and anti-condensation heating device can also be set according to user needs. Explosion-proof structure of the motor is explosion-proof type of cylindrical, planar and axial curved road.
