Xi’an Taifu Simo YRKK Series High-Voltage Wound Rotor Three-Phase Asynchronous Motor Model Explanation
Taking the Simo motor model YKK3551-4 as an example: YRKK indicates a wound rotor asynchronous motor with an enclosed air-to-air cooler; “3551” represents a frame center height of 355mm and core length of 1 unit; “4” represents the number of poles.
Overview of the Xi’an Taifu Simo YRKK Series High-Voltage Wound Rotor Three-Phase Asynchronous Motor
The YRKK series 6KV and 10KV wound rotor three-phase asynchronous motors are the latest products developed in China during the 1980s, with power levels and installation dimensions conforming to IEC (International Electrotechnical Commission) standards.
The YRKK series motors are characterized by high efficiency, energy savings, low noise, minimal vibration, light weight, reliable performance, and ease of installation and maintenance.
The Xi’an Taifu Simo YKK series (H355-1000) high-voltage three-phase asynchronous motor can provide high starting torque with a relatively small starting current. It is particularly suitable for situations where the feeder line capacity is insufficient to start squirrel-cage rotor motors, where the starting time is longer, where starting occurs frequently, and where minor speed adjustments are required. Typical applications include driving winches, rolling mills, wire drawing machines, etc.
The YRKK series motors adopt an F-class insulation structure. The bearing structure is designed according to IP54 standards, with grease lubrication that allows for oil addition and discharge without stopping the motor.
The protection level of the YRKK series motors is IP44 or IP54 (as per GB4942.1), the cooling method is IC611 (as per GB/T1993), and the structure and installation type is IMB3 (as per GB997). The motor’s rating is based on a continuous duty (S1) as the reference standard. The rated frequency is 50Hz, and the rated voltage is 6KV or 10KV. Other voltage levels or special requirements can be arranged with the manufacturer at the time of order.
