Technical Parameter Sheet of Model YX355-2-220kW

Revised Product Description

1. Product Profile

Our company has over 30 years of experience in developing and manufacturing high-voltage three-phase induction motors under the YX series.

In recent years, major upgrades have been carried out across the motor’s core components and manufacturing workflow: we adopted advanced high-performance insulation materials, low-loss silicon steel sheets, refined production craftsmanship, plus optimized structural design. These comprehensive improvements effectively cut various power losses inside the motor and boost overall energy efficiency by roughly 20%.

Manufactured with premium raw materials and standardized production procedures, this motor series features outstanding energy efficiency, low vibration, stable continuous operation, and simple installation & maintenance.

All technical indicators including power ratings, electrical performance, mounting dimensions and dimensional tolerances fully comply with IEC34-1 Rotating Electrical Machines – Rating and Performance standards, meeting universal criteria for machinery and mining equipment worldwide.

Five enclosure protection grades are available for this motor range: IP23, IP44, IP54, IP55 and IP56, all designed in line with IEC34-5 Enclosure Protection Class for Rotating Electrical Machines.

The base IP23 model can be modified into IP44 (duct ventilation version) or IPW24 (climate-proof variant). Customized motors with alternative protection ratings can also be provided upon clients’ special requests.

For cooling systems, IC01, IC81W and IC611 solutions are compliant with IEC34-6 Cooling Methods for Rotating Electrical Machines. Custom cooling configurations are offered if customers require other cooling types.

To specify the standard cooling setup for each sub-series: the base YX series comes with IC01 cooling, YXKS series matches IC81W, and YXKK series adopts IC611. All three sub-lines support upgrades to IP54, IP55 or IP56 protection levels.

This motor series applies the IMB3 mounting structure (horizontal foot-mounted), which satisfies all requirements defined in IEC34-7 Rotating Electrical Machines – Types of Construction and Mounting Arrangements.

The attached data sheet covers full technical parameters and installation dimensions for YX, YXKK and YXKS motors from frame size H355 to H1120, with 10kV rated voltage and three cooling types: IC01, IC81W, IC611.

2. Application Scope

These high-voltage motors serve as drive units for a wide array of general industrial machinery, such as compressors, ventilation blowers, water pumps, unloader equipment and conveyor systems. They act as prime movers for facilities in mining, general manufacturing, petrochemical and power plant sectors.

If clients order motors to drive heavy machinery with massive rotational inertia – including blowers, coarse grinding mills, rolling machines, roller presses, crushers and belt conveyors – you are required to submit complete technical data of the matched equipment and sign a dedicated technical agreement with our team. We will design tailor-made motors to guarantee long-term reliable running under heavy-duty working conditions.
