Detailed Description
The following embodiments are further described with reference to the drawings, wherein the motor is convenient to install.
Example 1
The embodiment provides a frequency conversion integrated machine convenient for hoisting, which comprises a motor 1 and a frequency converter 2 fixedly connected through bolts and also comprises a hanging plate 3, wherein the hanging plate 3 is a steel plate and is vertically welded on the outer circumferential surface of a base 4 of the motor 1; the number of the hanging plates 3 is 4, 2 hanging plates are divided into one group, 2 hanging plates 3 in each group are symmetrically distributed on two sides of a vertical central shaft surface of the machine base 4, the 4 hanging plates 3 are all positioned on the same horizontal plane, and the two groups of hanging plates 3 are respectively positioned on the circumferences of the front half part and the rear half part of the machine base 4; the lifting plate 3 is provided with lifting holes 5 for lifting the frequency conversion integrated machine, and the distance between the circle centers of each group of 2 lifting holes 5 is larger than the width of the frequency converter 2.
