1. Overview General Introduction

The Y series 6KV and 10KV high-voltage three-phase asynchronous motors are squirrel cage cast rotor motors designed and produced using the latest domestic high-voltage motor technology. Its protection level is IP23 (GB4942.1), and the cooling method is IC01 (see GB/T1993).

This series of motors has the characteristics of high efficiency, energy saving, low noise, small vibration, light weight, reliable performance, easy installation and maintenance, and has good insulation performance and moisture resistance. It can be directly used in 6KV and 10kV power grids without the need for intermediate transformer equipment.

Suitable for driving various mechanical equipment with coupling transmission, such as ventilation fans, compressors, water pumps, crushers, cutting machines, and other equipment, and can be used as prime movers in coal mining machinery industry, power plants, and various industrial and mining enterprises.

The structure and installation type of this series of motors are IMB3, and the rating is based on the continuous working system (S1) as the continuous rating. The rated frequency is 501-1Z, and the rated voltage is 6KV and 10KV. If the user has special requirements, they can be mutually agreed upon when placing an order.

Y-series(6KV/10kv)squirrel-cage three phase asynchronous motor,is building on the advanced technology in the nation. The protection degree of the motor is of IP23(according toGb4942.1),and the cooling method is IC01(according to GB/T1993).

The motors has a lot of advantages such as height efficiency ,enerty-saving,low noise and vibration ,light weight and reilable performance . THey are easy for installation andmaintenance. The motor has high insulation class and moistureproof capacity.

The motor is used to drive various mechanical equipments such as blowers ,pumps,crushers,storkremoing machines and other equipments,It can serve as the prime movers in coalmines,mechanical industries,powerplants and various industrial enterprises.

3. Structure Description Brief Construction

3.1 The electric motor is an internationally popular box structure, with the base and end cover welded from steel plates, which has good rigidity and light weight. The top of the electric motor adopts a closed air air cooler, which is easy to disassemble and assemble, and is conducive to the maintenance and repair of the electric motor.

3.2 The stator winding adopts F-class insulation material and protective material. The end of the stator winding is fixed with special binding technology, which is firm and reliable. The entire stator is treated with vacuum pressure impregnation F-machine solvent-free (VPI) treatment. Therefore, electric motors have excellent and reliable insulation performance, as well as moisture resistance and impact resistance.

3.3 Most of the squirrel cage rotors in this series of motors are made of cast aluminum, which ensures reliable operation; The squirrel cage copper bar rotor adopts advanced and reliable welding technology, and is fastened in the groove.

3.4 There are two types of bearings, rolling bearings and sliding bearings, depending on the power and speed of the motor. Their basic protection level is IP44. If the motor has a higher protection level, the protection level of the bearings will also increase accordingly. Electric motors using rolling bearings are equipped with non-stop oil filling and oil drainage rotation.

The main junction box is a sealed structure with a protection level of IP54. It is generally installed on the left side. The inlet holes of the outlet box can be switched up, down, left, and right in all directions. There is a separate grounding terminal inside the box.

3.1 The motor adopts compacted box structure,welding-jointed steel plate forits frame,light weight ,rigid in construction,there is closed air to air coolers on the stator frame convenient for installation and maintenance.

3.2 Stator winding adopts F class insulation and its end adopts firm binding. The whole stator adopts solvent-free varnish Vacuum pressure impregnation(VPI) to ensure the stator has excellent electric property and humidity resistance.

3.3 Rotor is made of cast aluminium or copper bar. Aluminium rotor is made of pure aluminium,copper barwedging copper rotor enhances the entorety of rotor.

3.4 The motor adopts rolling bering or sliding bering ,according to the output power and rotary speed.bearing protection grade normally is IP44.If the motor's protect grade increases,so does the berings'. Rolling bearing adopts iubricating gresse and its grease charger and discharger can be charged or discharged without stopping the motor.

3.5 The junction box is of IP54 protection grade and it is usually mounted on the motor's right side(viewed from shaft extension end.)Lt is also can be mounted on the left side and its outlets have four optional orientations(up,down ,left or right.)Separated grounding unit is available in main junction box,too.
