Y2 series three-phase asynchronous motors are the basic cases of low-voltage three-phase cage-type asynchronous motors for general use, which are updated and designed on the basis of Y series motors. The new basic series is divided into two designs. The first design, namely Y2 series (IP54) three-phase asynchronous motors, is the most complete series of low-voltage cage-type three-phase asynchronous motors in China. This series can meet the needs of general use at home and abroad, with a frame range of 63~355. The second design, namely the Y2-E series (IP54) three-phase asynchronous motor, is suitable for long-term continuous operation and high load rate applications, such as fans and water pumps. The motor has high efficiency and energy saving effect, and the frame range is 80~280. The basic series of three-phase parallel motors (IP54) includes two basic designs, the Y2 series and the Y2-E series. Under the general title of "Technical Cases of Three-Phase Asynchronous Motors", it is divided into two independent parts!
