Structural characteristics of YX high-voltage high-efficiency motor
The electric motor adopts a box shaped structure, and the base is welded into a box shape from steel plates, which is lightweight and has good rigidity. The top of the motor YX is equipped with a protective top cover and YXKS is equipped with an air-water cooler.
The stator adopts an external pressure structure, and the stator winding adopts 155 (F) grade insulation material. The 10kV motor adopts reliable anti corona measures, and the winding ends are reliably fixed and tied, and treated with vacuum pressure impregnation solvent-free paint process (VPI). Therefore, the motor has good insulation performance, high mechanical strength, strong moisture resistance, and long service life.
The squirrel cage rotor has two structures: cast aluminum and copper bars, which are manufactured using advanced and reliable cast aluminum or welding processes, and have undergone dynamic balance verification. Therefore, the motor runs smoothly and reliably.
The bearings are in two forms: rolling bearings and sliding bearings, determined by the power and speed of the motor. The rolling bearings are equipped with non-stop oil injection and discharge devices.
The main junction box is placed on the right side of the motor (viewed from the shaft extension end), or can be placed on the left side according to user requirements. Both the inside and outside of the junction box are equipped with separate grounding terminals. When the power is ≥ 2000kW, the motor is equipped with a neutral point junction box.
