YB2 series flameproof three phase asynchronous motor is the upgrading of the company YB series products is a basic series of explosion-proof motor. This series has the advantages of small size, light weight, beautiful appearance, safe and reliable operation, long life and excellent performance, installation and easy maintenance features.

This series of motor power rating, mounting dimensions conform to the standards of the International Electrotechnical Commission (IEC), the corresponding relationship with the German DIN42673 standard, the matching of the export of equipment and spare parts imported equipment.

This series motors are explosion-proof performance in line with GB3836.1-2000 "explosive gas atmospheres the electrical prepare Part 1: General requirements and GB3836.2-2000" explosive gas atmospheres - electrical equipment - Part 2: Flameproof "d" " shall also comply with IEC79-1, BS4683 and EN50018 requirements made of flameproof. The proof mark ExdI ExdIIAT4, ExdIIBT4 place with the presence of explosive gas mixtures.

ExdI apply to the explosive mixture of methane or coal dust coal mine mining face environment.
ExdIIAT4 for factory Class IIA, temperature class T1, T2, T3, and T4 group explosive gas mixture environment.
ExdIIBT4 for factory class IIB, temperature class T1, T2, T3, and T4 group explosive gas mixture environment.

Second, the Structure

The explosion-proof structure of the motor ExdI, ExdIIAT4, ExdIIBT4.
The main motor enclosure protection rating of IP55.
Motor cooling method is IC410, IC411.
Motor insulation class F, the stator winding temperature margin, long life.
The motor has a cylindrical shaft, by coupling or spur gear transmission.
Motor stator windings of high-strength polyester enamelled round copper wire, and the VPI vacuum pressure impregnated, processing as an integrated whole, winding and insulation has good
Good electrical, mechanical, moisture resistance and thermal stability.
Motor rotor with cast aluminum structure, the parity of the rotor by balancing the motor running smoothly, small vibration, low noise.
Given motor, the rotor plate with high permeability, low-loss high-quality electrical steel, motor, low loss, high efficiency.
Bearing motors use low vibration, low noise bearings, frame size 132 and below, double sealed bearings, shaft end with a wave spring washer to moderate Beat rely on bearings, effectively inhibited the vibration and noise generated when the motor running; frame size 160 and above, the inner and outer cover structure, and the bearing parts of the ring axial fixation to prevent axial movement of the motor rotor.
To make the motor safe and reliable operation, the frame size 180 and above motor bearing structure set Note row of oil installations, frame size 250 and above, motors, and reserved the position of the bearing temperature monitoring sensor.
