Abstract: An electric machine including a stator and a frame, the stator is supported with support necks on the frame in at least two axially spaced support locations. The support locations include a first group of support necks and a second group of support necks. The support necks in the first group are positioned in connection with a vertical centre plane. The second group includes two side support necks positioned opposite to each other at an angular distance above or below a horizontal centre plane. The angular distance is defined by a first angle which is determined in degrees by the formula α1=(90/P)±(⅕)*(90/P), where P is the number of poles of the electric machine and P>2.

Abstract: A rotation apparatus comprises a machine base and a stator. The machine base comprises a driving end intermediate support board and a non-driving end intermediate support board disposed parallel along the length direction of the machine base. Inner holes used for supporting the stator are separately provided in the driving end intermediate support board and the non-driving end intermediate support board. The inner holes in the driving end intermediate support board are asymmetrical on the top and the bottom. The vibration of the rotation apparatus can be effectively reduced, the output power is improved, and a good cooling effect is provided.
