YRKK series high - voltage wound - rotor three - phase asynchronous motors.

Model Description of Simo's YRKK Series High - Voltage Wound - Rotor Three - Phase Asynchronous Motors in Xi'an

Take Simo Motor YKK3551 - 4 as an example: YRKK represents a wound - rotor asynchronous motor with a closed air - to - air cooler; "3551" indicates that the center height of the frame is 355mm and it has a No. 1 core length; "4" represents the number of poles.

Overview of Xi'an Simo YRKK Series High - Voltage Wound - Rotor Three - Phase Asynchronous Motors

The YRKK series 6KV and 10KV wound - rotor three - phase asynchronous motors are the latest products in China in the 1980s. Their power ratings and installation dimensions comply with the standards of the International Electrotechnical Commission (IEC).
The YRKK series motors 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 YKK series (H355 - 1000) high - voltage three - phase asynchronous motors can provide a large starting torque with a small starting current; when the capacity of the feeder line is insufficient to start a squirrel - cage rotor motor; when the starting time is long and the starting is relatively frequent; and in occasions where a small - range speed regulation is required. For example, they are used to drive winches, rolling mills, wire - drawing machines, etc.
The YRKK series motors adopt a Class F insulation structure. The bearing structure is designed according to IP54, and grease lubrication is used, allowing for oil addition and drainage without shutting down the machine.
The protection level of the YRKK series motors is IP44 or IIP54 (see GB4942.1), the cooling method is IC611 (see GB/T1993), the structure and installation type is IMB3 (see GB997), the rating is a continuous rating based on the continuous duty system (S1), the rated frequency of the motor is 50HZ, and the rated voltages are 6KV and 10KV. For other voltage levels or special requirements, they can be negotiated with the manufacturer when placing an order.
