1 1KW, but kaicheng uses a 6-pole motor with 930 rpm. Generally, insomnia changes from 1380- 1400 to 4 poles. The 1 1KW-6 pole of Kaicheng (original) or 10T of Kaicheng must be used. +03KW is more powerful. Theoretically, it can reach 20T. Kaicheng is a Sino-Japanese joint venture. It follows the frugal style of Japan. Don't look at 1 1 1kW 16T. Not as good as 10T 13KW. The main reason is that their wire ropes are wound in different ways. 10T is twice the ratio of double rope and double winding. It is impossible to make a simple power comparison. 16T is indeed 1 1KW.
