Abstract: A field of electric motors, such as electric motors and electric generators for industrial applications, and more particularly to an electric motor. The electric motor of the present invention includes a rotor including a shaft and a rotor core supported on the shaft, a stator surrounding the rotor, a motor frame surrounding the stator and including a first end plate at a drive end of the electric motor, and a bearing shield attached to the first end plate, wherein a non-drive end of the electric motor is supported by a non-drive end supporting foundation, and a drive end of the electric motor is configured to be mounted together with a load with help of an adjustment flange, and wherein the electric motor further includes at least three threaded adjustment pieces fixed to the bearing shield or to the adjustment flange, and at least three threaded adjustment screws, each of the adjustment screws configured for being driven through a respective threaded adjustment piece and for moving the adjustment flange radially.

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.
