Electric motor with adjustment flange between motor and a load

A method for aligning a load with an electric motor, which includes:

• a rotor having 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 said electric motor;
• a bearing shield attached to said first end plate;
• and
• an adjustment flange mounted to said first end plate with mounting bolts, said adjustment flange comprising two annular end portions joined together with a number of axial beams,
• wherein a non-drive end of said electric motor is supported by a non-drive end supporting foundation, and a drive end of said electric motor is configured to be mounted together with a load with help of an said adjustment flange, and
• wherein said electric motor further includes:
• at least three threaded adjustment pieces fixed to said bearing shield or to said adjustment flange;
• and
• at least three threaded adjustment screws, each of said adjustment screws configured for being driven through a respective threaded adjustment piece and for moving said adjustment flange radially, and
• wherein said at least three threaded adjustment pieces comprise one threaded adjustment piece for each axial beam of said adjustment flange,
• said method comprising:
• mounting said adjustment flange to said electric motor;
• measuring required alignment correction from the shaft of said electric motor;
• calculating applied adjustment for each utilized adjustment piece based on said measured required alignment correction;
• loosening the mounting bolts of said adjustment flange slightly to allow radial movement of said adjustment flange;
• adjusting the adjustment screws of each of said utilized threaded adjustment pieces in accordance with said calculated adjustments for moving said adjustment flange radially;
• and
• tightening the mounting bolts of said adjustment flange for securing said adjustment flange.
