Take the Xi'an Simo YR series (IP44) three-phase asynchronous motor YR355M1-4 as an example. "Y" represents an asynchronous motor; "R" represents a wound rotor type; "355" indicates the center height of the motor (in mm); "M" is the code for the frame length; "1" is the code for the core length; "4" represents the number of poles of the motor.
The Xi'an Simo YR series (IP44) three-phase asynchronous motors have the advantages of high efficiency, energy saving, low noise, small vibration, safe and reliable operation, and convenient installation and maintenance. They can be used for various general-purpose machines, such as ball mills, fans, compressors, water pumps, crushers, machine tools for cutting, transportation machinery, etc., as prime motors. In addition, they can also be used to drive machines with large moment of inertia, such as fans, coal pulverizers, rolling mills, hoists, and electric shovels.
The YR series motors are general-purpose wound-rotor three-phase asynchronous motors. Their power ratings and installation dimensions comply with IEZ standards. The enclosure protection level is IP44, the cooling method is IC44, and the duty is continuous (S1).
The YR280-315 motors comply with the provisions of "Technical Conditions for YR Series (IP44) Three-phase Asynchronous Motors" JB/7119-1993. The YR355 is independently developed by our factory and complies with the provisions of the technical conditions OXD.510.083.
The Xi'an Simo YR series (IP44) three-phase asynchronous motors adopt Class F insulation. The rated voltage is 380V, the rated frequency is 50HZ, with the stator connected in △ and the rotor connected in Y.

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.
- When placing an order, please first refer to the product catalog to determine the model specifications and other data of the required product. Try to select the standard specification products listed in the catalog. Please indicate the motor model, power, speed regulation, voltage, frequency, noise, and installation type in the order contract. If the noise level is not specified, it will be supplied as level 2.
- For 2-pole motors with a power of 5.5KW and above and 4-pole motors with a power of 38KW and above, belt drive cannot be used.
- If there are no special requirements, the default parameters of Simo Motor are: the installation method is horizontal B3, the insulation class is Class B, and the protection level is IP44.
- If there are special requirements, such as double shaft extension, reverse terminal box position, reverse rotation of the shaft, requirements to be made into a wet tropical type, outdoor anti-corrosion type, or others, they need to be clearly indicated in the contract and contact our factory in advance.
