Take the Xi'an Simo YR series (H355 - 1000) high - voltage three - phase asynchronous motor YR3551 - 4 as an example: "YR" represents a wound - rotor asynchronous motor; "3551" indicates that the center height of the frame is 355mm and the core length is of No. 1 type; "4" represents the number of poles.
The YR series (H355～1000) 6KV, 10KV high - voltage three - phase asynchronous motors are wound - rotor asynchronous motors. The protection level of this series of motors is IP23, and the cooling methods are IC01, IC11, IC21 or IC31 (see GB/T1993). Among them, the motors of H355～630 are produced according to the technical conditions of JB/T7594 - 94 and JB/T10445 - 2004, and the motors of H710～1000 are produced according to the technical conditions of GB/T13957 - 1992.
The Xi'an Simo motors of the YR series have the advantages of high efficiency, energy conservation, low noise, small vibration, light weight, reliable performance, and convenient installation and maintenance.
The Xi'an Simo YR series (H355 - 1000) high - voltage three - phase asynchronous motors can provide increased starting torque with a relatively small starting current and can adjust the speed within a certain range. They are suitable for situations where: the capacity of the feeder line is insufficient to start a squirrel - cage rotor motor; the starting time is long and the starting is relatively frequent; and a small - range speed adjustment is required. For example, they are used to drive hoists, rolling mills, wire drawing machines, etc.
The YR series motors adopt a Class F insulation structure. The bearing structure is designed according to IP54. Grease lubrication is used for H355～630, and forced thin oil lubrication with sliding bearings is used for H710～1000.
The structure and installation type of the YR series motors are IMB3. The rating is a continuous rating based on the continuous duty system (S1). The rated frequency of the motors is 50Hz, and the rated voltages are 6KV and 10KV. For other voltage levels or special requirements, they can be jointly agreed upon with users when placing an order.
Simo Motor (Group) Co., Ltd. is a large domestic enterprise specialized in manufacturing large and medium - sized, high and low - voltage, AC and DC motors. It is a systematic power system provider integrating motor design and manufacturing, electrical control, mechanical processing, mold, casting, transportation and other automation and complete projects. Its production and sales scale ranks among the top in the national motor industry, maintaining a high - speed growth trend for 7 consecutive years. It was shortlisted in the top 500 of China's machinery industry in 2004 and ranked 58th in China's electrical industry in 2005. In 1995, it took the lead in obtaining the ISO9001 - 1994 quality system certification in the industry. In August 2005, it passed the ISO9001 - 2000 quality system certification of the China Quality Certification Center (CQC). In May 2006, it passed the ISO14000 environmental management system and OHSAS18000 occupational health and safety management system certifications. At the same time, it passed the European "CE", American "UL" and national mandatory "CCC" certifications. It is a quality and credit AAA - level enterprise. Its leading products have successively won honorary titles such as "Ministry/Provincial/Municipal Famous Brand Products", "Xi'an Inspection - free Products", and "China Glory Famous Brand Products".
In order to improve the quality of various electromechanical products, strengthen pre - sales and after - sales services, and make customers feel at ease and satisfied, Simo Motor resolutely implements the "Quality Assurance Statement" of eight scientific research and design institutes in the machine tool industry of the Ministry of Machinery Industry, conscientiously implements all the clauses in the statement, and strictly follows the rules and regulations of the ISO9001:2000 quality management system to ensure:
- Seriously implement relevant national standards, and strictly manufacture and inspect the products according to the standards or contract technical requirements. Unqualified products will not leave the factory.
- After the final assembly and on - line commissioning of various finished products such as product measurement bases, the assembly personnel conduct a 72 - hour running test before delivery. Strictly conduct running - in tests and reliability tests according to relevant standards to improve the reliability of new products and eliminate early failures.
- Under normal sales conditions, the above - mentioned finished products are delivered strictly on schedule. Functional components are guaranteed to be supplied within three months, and can be supplied in advance in special cases. In case of delay, compensation will be implemented according to the "1997 New Measures for Quality Improvement".
- When customers find quality problems during the use of products, a reply will be made within 24 hours after receiving the customer's notice. For on - site services, start within 48 hours and ensure that maintenance personnel do not withdraw until the fault is eliminated.
- Complete technical documents are provided when the product leaves the factory. All product quality problems are covered by three guarantees (repair, replacement, return). If the product still does not meet the factory requirements after repair, the product will be returned or replaced.
- Simo Motor products are guaranteed for lifetime maintenance at cost after being sold.
