Method of forming a secondary for linear drive motor comprising sheet of highly permeable magnetic material having synchronized motor teeth, encoder teeth, and commutation tracks integrally formed therein |
摘要 |
A method for forming a secondary for a motor, for instance a linear drive motor, includes providing a sheet of highly magnetic permeable material with a plurality of slots extending through the sheet spaced along a length of the sheet. The slots define a plurality of teeth in the sheet and enable the sheet to be conformable to a mounting surface when forming the secondary of the motor. The top surface of the sheet has a plurality of pockets formed adjacent the plurality of slots. The pockets extend parallel to the width and are spaced along the length of the sheet. The pockets form a sensor operatively connected to a control of the motor. The sensor may be an encoder, and/or operatively connected to a control for controlling commutation of the motor, and/or setting positional limits, absolute positional information, and/or providing information about the sheet.
