Abstract
In a method of mounting attachment parts to an electric machine, a rotor of the electric machine is non-rotatably supported in a bearing device. A stator of the electric machine is detachably secured in a predefined first installation position by a clamping device, and a first attachment part is mounted to the stator. The clamping device is then released, and the electric machine is operated as motor for a time period sufficient for the stator to rotate in relation to the rotor until reaching a second installation position. The stator is secured by the clamping device in the second installation position, and a second attachment part is mounted to the stator.
Claims11
A method of mounting attachment parts to an electric machine, said method comprising steps in a following order:
- non-rotatably supporting a rotor of the electric machine in a bearing device;
- detachably securing a stator arranged in a stator housing of the electric machine in a predefined first installation position by a clamping device, wherein the stator is secured by clamping the stator housing of the stator via the clamping device;
- mounting a first attachment part to the stator housing;
- releasing the clamping device;
- operating the electric machine as a motor while the stator together with the stator housing rotates in relation to the rotor until reaching a second installation position;
- securing the stator via the stator housing by the clamping device in the second installation position;
- and
- mounting a second attachment part to the stator housing,
- wherein the clamping device comprises laws arranged external to the stator housing.
A method of mounting attachment parts to an electric machine, said method comprising steps in a following order:
- clamping a stator arranged in a stator housing in a first installation position that allows access from above by externally clamping the stator housing with jaws;
- lowering a first attachment part onto the stator housing in the first installation position and mounting the attachment part to the stator housing;
- releasing the stator housing from the jaws;
- moving the stator with the first attachment part in relation to a stationary rotor of the electric machine away from the first installation position to a second installation position which corresponds to the first installation position as occupied by the stator for mounting the first attachment part;
- clamping the stator by externally clamping the stator housing with the jaws;
- and
- lowering a second attachment part onto the stator housing in the second installation position and mounting the second attachment part to the stator housing.
