Three-phase asynchronous electric motors YXKK355-4-250KW-10KW (IP55, IC611)

A welded steel box base is used, providing high rigidity, low weight and excellent vibration resistance. The center height of the base is 355mm, the default is IMB3 horizontal installation with supports. Bearings can be either rolling or sliding. The rolling bearings are equipped with a continuous oil supply and drainage device, while the sliding bearings use a composite lubricant, which simplifies maintenance and provides improved protection.

It is a three-phase asynchronous motor with a squirrel-cage rotor. The rotor is mainly made of copper rods (optional cast aluminum), precisely welded and slotted, ensuring stable performance. The stator has an external press-fit design coupled with low harmonic windings and magnetic slot wedges to reduce losses. The Class F insulation system is treated with VPI technology to provide moisture and impact resistance, suitable for 6kV and 10kV high voltage environments, and can withstand high frequency surges.

The IC611 air cooling system is used. The fan combination optimizes the ventilation path, resulting in efficient heat dissipation, low power consumption and low noise, ensuring the temperature rise meets S1 duty cycle standards. Protection℃IP55, suitable for harsh operating conditions; Adjustable main distribution box installation and incoming wire direction, built-in independent grounding terminal to ensure the safety of high voltage wiring.

Achieving Level 2 energy efficiency with an electromagnetic design optimized through finite element simulation results in 20% lower losses compared to conventional high-voltage motors and 20% annual energy savings greater than Level 3 energy efficiency. Low harmonic windings and optimized ventilation systems improve energy efficiency, delivering significant long-term energy savings, making it suitable for energy-efficient and socially impactful projects.

Class F insulation combined with scientific heat dissipation and large thermal reserve ensures stable operation in altitudes of<=1000 m and temperatures from -15℃to 40 degree. High precision processing, low vibration and noise, copper rod rotor and reliable welding processes ensure trouble-free starting, stopping and operation under high voltage conditions, ensuring long service life.

Adaptable to high voltage of 6KV and 10KV and frequency of 50Hz, can drive a variety of general purpose equipment, and is widely used in mining, petrochemical and other industries. Standardized mounting dimensions ensure high interchangeability. Non-stop bearing maintenance and adjustable junction box design significantly reduce maintenance time and lower operating costs.

Compliant with numerous national and IEC standards, and ISO9001 certified, it features stable electrical performance without harmonic distortion and is grid-safe. The sealed high-voltage distribution box, independent grounding and multi-level protection system effectively prevent leakage and arcing, meeting the safety requirements of high-voltage equipment in the mining industry.
