Product Model Identification – Accurate Motor Specification Recognition
En Simo Motor YRKS series wound rotor air-to-water cooled high voltage motor adopts a standardized model naming system. Taking YRKS7101-4 as an example:
- “YRKS” designation: Enclosed wound rotor three-phase asynchronous motor with air-to-water cooler
- “7101” code:
- “710” indicates a frame center height of 710 mm
- “1” represents core length No.1
- “4” poles: Indicates a 4-pole motor configuration
This naming system strictly follows JB/T 7594-1994 technical standards, ensuring users can quickly and accurately identify key motor parameters for reliable equipment selection.
Technical Overview – Professional Design for Heavy-Duty Industrial Demands
Core Technical Features
En YRKS series three-phase asynchronous motors (center height 710–1000) are 10 kV wound rotor high voltage motors utilizing innovative air-to-water cooling technology. The protection class reaches IP44 or IP54, with a cooling method of ICW81A. The dedicated 10 kV voltage design allows direct connection to 10 kV power grids, simplifying system configuration, reducing investment costs, and lowering operational energy consumption.
Advanced Insulation System
The stator windings use high-calidad Class F insulation materials, with securely bound winding ends. During manufacturing, the windings undergo multiple inter-turn impulse voltage tests and power frequency withstand voltage tests. Advanced VPI (Vacuum Pressure Impregnation) solvent-free varnish technology is applied, ensuring excellent insulation performance, superior mechanical strength, and strong moisture resistance.
The rotor windings are made of high-purity copper conductors and also adopt Class F insulation, guaranteeing reliability under high-speed and high-load operating conditions.
Flexible Bearing Configuration
According to different power ratings and speed requirements, the YRKS series motors are available with both rolling bearings and sliding bearings. Motors with frame sizes H710–800 are equipped with professional sliding bearing structures to ensure stable operation under heavy loads. The standard protection class is IP44, with customized options available for other voltages, frequencies, and protection levels.
Core Technical Advantages – Solid Assurance of Superior Performance
Innovative Air-to-Water Cooling System
En YRKS series motors adopt the ICW81A cooling method, using a high-efficiency air-to-water heat exchanger to achieve optimal heat dissipation. Compared with traditional cooling solutions, air-to-water cooling performs exceptionally well in high-temperature environments and confined spaces, ensuring stable operating temperatures during continuous heavy-load operation.
Excellent Starting and Speed Regulation Performance
En YRKS series wound rotor air-to-water cooled high voltage motors provide outstanding starting characteristics, delivering high starting torque with relatively low starting current. They are especially suitable for:
- Applications with limited grid capacity where squirrel cage motors cannot start
- Heavy-duty equipment requiring frequent starts or long starting times
- Industrial applications requiring speed regulation within a certain range
- Special equipment such as heavy-duty hoists, rolling mill units, and wire drawing machines
Robust Box-Type Structural Design
The motor features a high-strength box-type structure with excellent mechanical strength and rigidity. The mounting arrangement is IMB3, designed for continuous duty (S1 rating), ensuring adaptability to harsh industrial environments.
Energy-Saving and Environmentally Friendly Design
Through optimized electromagnetic design combined with advanced cooling technology, the YRKS series motors achieve high energy efficiency, low noise, low vibration, and reduced weight while maintaining reliable performance, fully meeting modern industrial requirements for energy saving and environmental protection.
