1. Product Description
YX series high voltage three-phase induction motor is designed and developed by our company and it has more than 30 years experience history. With the improvement of insulation material performance of the motor in recent years, the application of low consumed silicon steel sheet, the enhancement of craftwork level, and the optimization and improvement of design, which have the ability to reduce all kinds of consumptions of motors, generally reduce over about 20%, thus increase the motor efficiency.
This series products adopt the high quality materials, good manufacturing process, have the characteristics of high efficiency, energy saving, small vibration, reliable operating and convenient for mounting and maintenance.
The power grade, electric property, mounting dimensions and tolerance are in coincident with International Electrical Committee standard IEC34-1 Rotating Electric Motor Rating and Property and machinery industry standards etc.
The enclosure protections of this series of motor include 5 types, i.e. IP23, IP44, IP54, IP55 and IP56 in accordance with the standard of the IEC34-5 Enclosure Protection Class of Rotating Electrical Machine. The IP23 motor can be changed to IP44 (pipeline ventilation) or IPW24 (climate protection type). If the users need other protection class, we may also provide relevant products.
The cooling method of this series of motor is IC01, IC81W and IC611 in accordance with the standards of IEC34-6 Cooling Methods of Rotating Electrical Machine. If the users need other cooling methods, we may also provide relevant products.
The protection class of the YX series motor (IC01) is IP23, YXKS series (IC81W), YXKK series (IC611) is IP44, which also can be made into IP54, IP55 and IP56.The structure and Installation method of this series of motor is IMB3 (horizontal with footing), which complies with the specifications of IEC 34-7 Motor Structure and Mounting Type Code.
This sample table lists the technical data and installation sizes of (H355~1120) 6kV, 10kV, IC01, IC81W, IC611 in YX, YXKK and YXKS series.
2. Application
This series of motor may be used for driving all kinds of general machines such as the compressor, ventilation fan, water pump, stock-removing machine, transportation machines and other mechanical equipment, and are applied as the prime mover in all industrial and mining enterprises such as the mine, machinery, petrochemical industry and power plant, etc. If the users place an order for the motors that are used for driving the machines with huge rotary inertia such as the blower, coal grinder, rolling machine, crusher, belt machine, etc, they shall provide us with relevant technical data, sign the technical agreement with us as the basis for specific design of motor to ensure the reliable operation of motor.
