1 . Overview
YBF series high-voltage explosion-proof three-phase asynchronous motor for fan is a new product designed and developed by SEALOCEAN explosion-proof combined with the introduction of German Siemens high-voltage explosion-proof motor design and manufacturing technology, and based on our company’s years of production and manufacturing experience. It has a small size and weight. Lightweight, high efficiency, low noise, low vibration, safe and reliable operation, convenient use and maintenance, etc.
The power level and installation dimensions of YBF series high-voltage flame-proof three-phase asynchronous motors for wind turbines conform to my country's standards and the International Electrotechnical Commission's IEC standards, and have contemporary domestic leading technical levels.
YBF series of high-voltage flameproof three-phase asynchronous motors for fans implement standards GB3836.1-2000 "Electrical Equipment for Explosive Gas Atmosphere Part 1: General Requirements" and GB3836.2-2000 "Electrical Equipment for Explosive Gas Atmosphere Part 2: Part 2: Explosion-proof type "d"" is made into an explosion-proof type with the explosion-proof mark ExdI, which is mainly used as the prime mover of the wind turbine.

3. Structure description
This series of motors use Siemens motor manufacturing technology, the insulation class is F, the stator coil is wound with mica tape-coated film wrapped rectangular copper wire, the winding end of the coil is suitable for material selection, and the steel end hoop is tied to the outer end. , The stator core with windings is impregnated with solvent-free paint by VPI vacuum pressure. Therefore, the stator winding has high electrical strength, mechanical strength, insulation performance, moisture resistance and thermal stability.
The rotor adopts cast aluminum rotor (frame size 400-450) or copper bar rotor (frame size 560-710). After high-precision balancing, the motor runs smoothly and has low vibration.
The high-voltage junction box is half-open, with a large wiring cavity and a cable head position.
The bearing structure adopts a three-bearing structure, and the shaft extension end adopts a double bearing (one of which is a four-point angular contact ball bearing), which can bear a large axial force while bearing the radial force, and the operation is safe and reliable.
Both ends of the motor are equipped with non-stop lubrication devices, which can regularly replenish lubricating grease.
Bearing temperature measuring devices are installed at the bearings at both ends of the motor, and the bearing temperature measuring devices are used to monitor the bearing temperature.
A stator temperature measuring device and an anti-condensation heating device are arranged at the stator winding of the motor. The stator temperature measuring device is used to monitor the temperature of the stator coil, and the stator anti-condensation heating device is used to prevent the stator coil from being damp and the insulation resistance is reduced.
The motors of this series of motor frame sizes 400-450 adopt IC411 cooling method; the motors of frame size 560-900 adopt IC511 cooling method.
