YB2-112M-4 flameproof three-phase asynchronous motor

Structural features
The flameproof structure of the motor has the following features:

The protection level of the motor body shell is.

The cooling method of the electric motor is,.

The insulation level of the motor is Grade 1, the stator winding has a large temperature rise margin and a long life.

The electric motor has a cylindrical shaft extension and is driven by a coupling or spur gear.

The stator winding of the motor is made of high-strength polyester enameled round copper wire, which is processed by vacuum pressure impregnation to form a complete whole. The winding and insulation have good electrical, mechanical, moisture-proof performance and thermal stability. properties, and marine motors undergo special anti-enzyme bacteria treatment at the ends.

The motor rotor adopts a cast aluminum structure. The rotor has been dynamically balanced and verified. The motor runs smoothly, has small vibration and low noise.

The stator and rotor stampings of the motor are made of high-quality electrical silicon steel sheets with high magnetic permeability and low loss. The motor has low loss and high efficiency.

The motor bearings are made of low-vibration and low-noise bearings. Double-sided sealed bearings are used for the frame size and below. A wave spring washer is installed at the extension end of the shaft to lean against the bearing with moderate pressure, effectively inhibiting the operation of the motor. To generate vibration and noise, inner and outer cover structures are adopted for the frame size and above, and retaining rings are used to fix the bearing axially, effectively preventing the axial movement of the motor rotor.
