Y2 series motor can be used in various fields such as machine tools, water pumps, blowers and compressors as well as transportation, mixture, printing, agricultural machines and food processors where are no inflammable, explosive or corrosive gases. The mounting dimension and the power degree of Y2 series motor conform to IEC standard and DIN42673 standard of Germany. The protection degree of the frame is of IP54 and the cooling method of IC411 with continuous duty (SI). F-class insulation is used and the temperature rising is checked against B-class (except motors of H31512-2.4 and all the specifications of H355 which are checked against F-class). The noise level at load state is also checked.
