General description:YE4 (H80~355) series is a fully enclosed, self-fan cooled high, efficiency squirrel cage three-phase induction motor designed and developed by our company with high efficiency and energy saving, using new materials, new technology, and optimized design. YE4 series has a novel method, beautiful appearance, low noise, high torque, good starting performance, compact structure, convenient use, maintenance, etc.
Structure description:
(1) The motor base and end cover are made of high-strength cast iron, and the stator adopts an external press-fit structure. The stator winding is made of round copper wire scattered with soft grade F insulating material. The end of the winding is fixed by a unique binding process, which is firm and reliable. The entire stator is treated with vacuum pressure-impregnating solvent paint (VPI). The motor has reliable insulation performance and excellent moisture and impact resistance.
(2) The squirrel cage rotor of this series of motors adopts cast aluminum or cast copper rotor, which is reliable in operation; the bearing is a rolling bearing.
(3) H180~355 motors are equipped with non-stop refueling and oil discharge devices, and special refueling tools can be used for non-stop refueling and oil discharge.
(4) The main outlet box is a sealed structure, and the protection level is the same as that of the motor. The position of the main outlet box is generally installed on the top of the motor frame and can also be installed on the side of the structure according to the application. There is a separate ground terminal in the outlet box.
Application:
This series of motors can be used to drive various general machinery such as compressors, ventilators, water pumps, cutting machine tools, transportation machinery, and other mechanical equipment.
When YE4 is used to drive blowers, coal mills, rolling mills, winches, crushers, belt conveyors, and other machinery with large rotational inertia, relevant technical information should be provided when ordering. A technical agreement should be signed as the basis for the motor's unique design to ensure the engine's reliable operation.
Model Description:
According to the provisions of GB4831, the motor model is composed of two parts, product code and specification code which is composed of center height, core length serial number, and pole number.
