Abstract
An electromechanical device includes a rotor and a stator, wherein the stator includes multiple teeth excitable by a coil. The stator is formed from multiple stator sections with one section having a protrusion in spaced relation with a first tooth and a second section having a second protrusion in spaced relation with a second tooth. The protrusions have voids for receiving opposing protrusions in an overlapping manner to integrally form the first stator section with the second stator section. The electrical coil is extended around at least a portion of one tooth before mating the multiple stator sections. The rotor has a diametral magnetized magnet extending into the aperture.
Claims34
An electromechanical device comprising:
- a stator having an aperture extending axially therein, wherein the stator includes at least two teeth, with each tooth of the at least two teeth extending toward the aperture, the stator including multiple stator sections with at least one of a first stator section having a first protrusion in spaced relation with a first tooth and a second stator section having a second protrusion in spaced relation with a second tooth, the first protrusion having a first void therein for receiving the second protrusion therein, and the second protrusion having a corresponding second void therein for receiving the first protrusion therein in an overlapping manner to integrally form the first stator section with the second stator section;
- a rotor having a shaft and at least one diametral magnetized magnet operable therewith extending into the aperture, wherein a gap is formed between the magnet and the at least two teeth;
- and
- an electrical coil extending around at least a portion of one tooth of the at least two teeth, wherein the electrical coil is excitable for magnetizing the at least one tooth.
A method of assembling an electromechanical device, the method comprising:
- providing multiple stator sections, wherein a first stator section includes a first protrusion in spaced relation with a first tooth, wherein the first protrusion includes a first void therein, and wherein a second stator section includes a second protrusion in spaced relation with a second tooth, the second protrusion having a second void therein;
- forming an electrical coil around at least a portion of one tooth of the first and second teeth, wherein the electrical coil is excitable for magnetizing the at least one tooth;
- placing the first protrusion of the first stator section into the second void of the second stator section and placing the second protrusion of the second stator section into the first void of the first stator section in an overlapping manner to result in integrally forming the first stator section with the second stator section to form a stator having at least two teeth and an aperture between free ends thereof;
- and
- extending a rotor having a shaft and at least one diametral magnetized magnet operable therewith into the aperture, wherein a gap is formed between the magnet and the at least two teeth.
