YBXN flameproof three-phase asynchronous motor
YBXn series motor application range
YBXn series high-efficiency flameproof three-phase asynchronous motor is a basic series of fully enclosed, self-fan-cooled, squirrel-cage, high-efficiency explosion-proof three-phase asynchronous motor developed by our company. Efficiency Executes the energy-saving evaluation value standard in GB18613--2002 "Energy efficiency limit value and energy-saving evaluation value of small and medium-sized three-phase asynchronous motor", and has excellent performance, safe and reliable use, vibration and noise characteristics lower than similar products, and meets environmental protection requirements. .
The power class and installation dimensions of this series of motors comply with the International Electrotechnical Commission (IEC) standards, and their correspondence is the same as the German DIN42673 standard, which is conducive to the matching of export equipment and spare parts for imported equipment.
The explosion-proof performance of this series of motors complies with GB3836.l-2000 "Electrical Equipment for Explosive Gas Environments Part 1: General Requirements" and GB3836.2-2000 "Electrical Equipment for Explosive Gas Environments Part 2: Explosion-proof Type "d" It also conforms to the regulations of IEC7, l, BS4683 and EN50018, and is made into a type of explosion. The explosion-proof marks are Exdl, Exd11, AT4, and Exdl1BT4, which are suitable for use in places where explosive gas mixtures are present.
Exdl is suitable for use in underground coal mine non-mining face environments where explosive mixtures of methane or coal dust are present.
ExdlIAT4 and ExdllBT4 are suitable for use in factory Class 11 Class A and Class B, and temperature groups are in the presence of explosive gas mixtures of TI, TZ, T3 and T4.
On the basis of YBXn basic series motor, it can also be made into YBXn-W outdoor type, YBXn-TH wet tropical type, YBXn-THW outdoor wet tropical type, YBXn-TA dry tropical type, YBXn-TAW outdoor dry tropical type, YBXn one T tropical type, BXn-TW outdoor tropical type and YBXn-WFI outdoor medium anti-corrosion type and other climatic conditions.
The main technical parameters
Motor structure
1. The flameproof structure of the motor has d ll AT4, d IIBT4, d ll CT4.
2. The protection level of the motor main body is IP55.
3. The cooling method of the motor is IC41 1.
4. The motor insulation grade is F grade, and the stator winding has a large temperature rise margin and a long service life.
5. The motor has a cylindrical shaft extension, which is driven by a coupling or spur gear.
6. The stator winding of the motor is made of high-strength polyester imide enamelled round copper wire, which is treated by VPI vacuum pressure immersion paint to form a complete whole. The winding and insulation have good electrical, mechanical, moisture resistance and thermal stability.
7. The rotor of the motor adopts cast aluminum structure, and the rotor is verified by dynamic balance. The motor runs smoothly, the vibration is small, and the noise is low.
8. The motor stator and rotor punching plate adopt high-magnetic, low-loss high-quality cold-rolled electrical silicon steel sheet, which has low motor loss and high efficiency.
9. The motor bearing uses low-vibration and low-noise bearings for the motor. The double-sided sealed bearing is used for the frame number 132 and below. The wave spring washer is installed at the shaft end to effectively suppress the vibration and noise generated when the motor is running. 160 and above adopt the inner and outer cover structure, and the bearing ring is axially fixed at the bearing part, effectively preventing the axial movement of the motor rotor.
In order to make the motor run safely and reliably, the motor bearing structure of the frame number 160 and above is provided with an oil-discharge device, and the motor with the frame number 200 and above is reserved for the position of the bearing temperature monitoring sensor element.
10. Motor fan and hood: The motor adopts anti-static plastic fan, which has small moment of inertia and low loss. The whole series of fans and shafts are connected by keys and operate reliably. The windshield is a steel plate structure, which can prevent the intrusion of a certain size of foreign objects to obtain the largest ventilation area and make the wind path unobstructed.
