The outer contour of 1 The Y2 series motor frame is square and round, and the radiating fins are distributed in vertical and horizontal parallel, all of which are cast iron structures. In addition, H63 ~ 1 12 also has aluminum alloy die-casting structure.

2. This series of motors adopt shallow end cover structure, which increases the number and size of internal ribs, and all adopt cast iron structure. In addition, H63 ~ 1 12 also has aluminum alloy die-casting structure. In order to facilitate users' use and maintenance, non-stop oil injection devices are added in H 180 and above.

3. The protection grade of junction box is IP55. In order to reduce the weight of the motor, H63~280 junction box adopts aluminum alloy die casting (iron castings can also be used), and H3 15 ~ 355 adopts iron castings. In addition, there is a special grounding device in the box, and the installation position of the thermal protection device is considered to be the base of H 160 or above. The power inlet hole adopts double-hole wire inlet, and there are two sealing structures: one is the encryption cover, and the other is the locking seal. The junction box is generally located at the top of the base and can be wired from all sides. In addition, the junction box of H80~355 cast iron base can also be located at the side of the base.
