The 3 phase 4 pole squirrel cage induction motor (frame numbers 80-355) is a low-voltage fully enclosed self fan cooled ultra high efficiency squirrel cage three-phase asynchronous motor that meets the IE4 efficiency requirements in the latest version of the international standard IEC 60034-30 "Efficiency Classification of Single Speed Three Phase Cage Induction Motors". Its efficiency value fully meets the energy efficiency level 1 requirements in the international standard GB18613 "Energy Efficiency Limit Values and Energy Efficiency Grades for Small and Medium Three Phase Asynchronous Motors", which is currently the highest efficiency standard in the world. The efficiency is determined by the loss analysis method of measuring input-output power (according to the provisions of 11.3 in GB/T 1032-2012).
The installation dimensions and power rating of the electric motor comply with the IEC international standard, which is consistent with the German DIN42673 standard. Its enclosure protection level is IP55, the cooling method is IC411, and it operates continuously (S1). Adopting F-class insulation structure, but the temperature rise of the entire series is assessed as B-class; And require assessment of load noise.

The 3 phase 4 pole squirrel cage induction motor has a rated voltage of 380V, a rated frequency of 50Hz, and a power range of 0.75-375kW, including 2-pole, 4-pole, and 6-pole motors. Power of 3kW and below is the Y connection, while other powers are the Δ connection.
H80-160 machine base numbers are fully enclosed bearing structures, while H180 and above machine base numbers are open type bearings with non-stop filling devices on the front and rear axles. The motor is equipped with anti condensation drainage holes. The conventional wire box for electric motors has a top outlet, but it can also be made into a right or left outlet according to user requirements. The junction box can be rotated 90 ° and 180 °, making it convenient for users to wire out from different positions.
The 3 phase 4 pole squirrel cage induction motor is mainly used in various fields of the national economy, such as machine tools, water pumps, fans, compressors, and can also be applied to various power transmission systems such as transportation, mixing, printing, agricultural machinery, and food.
