Simo YKK Series (H355-1000) High-Voltage Three-Phase Asynchronous Motor Model Description
Example: Simo YKK Series (H355-1000) High-Voltage Three-Phase Asynchronous Motor
Taking the model YKK3551-4 as an example:
- “YKK” indicates a squirrel-cage rotor asynchronous motor with an enclosed air-to-air cooler.
- “3551” represents the center height of the motor frame, which is 355mm, and “1” denotes the core length.
- “4” specifies the number of poles.
Motor Overview
The Simo YKK Series (H355-1000) high-voltage three-phase asynchronous motor, rated for 6kV or 10kV, is a squirrel-cage rotor asynchronous motor. This series features a protection level of IP44 or IP54 and utilizes the IC611 cooling method (as per GB/T1993 standards).
Key Advantages:
- High efficiency
- Energy-saving
- Low noise
- Minimal vibration
- Lightweight
- Reliable performance
- Easy installation and maintenance
The YKK series motors are versatile, capable of driving various machinery such as fans, compressors, pumps, crushers, cutting machines, and more. They are suitable for use in coal mines, the mechanical industry, power plants, and various industrial and mining enterprises as prime movers.
The structure and installation type of the YKK series motor is IMB3, with a continuous duty rating (S1). The motor’s rated frequency is 50Hz, and the rated voltage is 6kV or 10kV. Other voltage levels or special requirements can be negotiated with the user during the order process.
For a 2-pole motor, when viewed from the shaft extension end, the rotation direction is clockwise. If a counterclockwise rotation is required, it must be specified at the time of order.
Technical Features of Simo YKK Series (H355-1000) High-Voltage Three-Phase Asynchronous Motor
The Simo YKK Series adopts a box-type structure, with the frame made of a welded steel plate box structure, which is lightweight and offers good rigidity. Both sides and the top of the frame are equipped with protective covers and plates. After removing these covers, the internal parts of the motor can be observed and accessed, making maintenance and repair convenient.
The stator uses an external pressure structure with a slide-in installation method. The stator winding is made of F-class insulation material with minimal resin, with reliable end fixation and binding. A vacuum pressure impregnation process using solvent-free paint ensures excellent insulation reliability, mechanical strength, and moisture resistance.
The bearings are available in both rolling and sliding types, depending on the motor’s power and speed. The basic protection level of the bearings is IP54, and this level can be increased if the motor requires higher protection.
