Abstract
A rotor including a cylindrical iron core having a through hole for receiving a rotational shaft, and a squirrel-cage conductive body including a plurality of conductive bars and a pair of annular conductive end rings provided at both ends of the plurality of conductive bars is provided. The conductive bars extend along a direction in which the rotational shaft is received and are arranged at an outer circumference of the iron core at certain intervals. The rotor further includes a conductive reinforcing layer extends on at least a part of an outer surface of the conductive end ring. The conductive reinforcing layer is formed by spraying conductive particles in a solid phase onto the outer surface of the conductive end ring.
Claims6
A rotor comprising:
- a cylindrical iron core having a through hole for receiving a rotational shaft;
- and
- a squirrel-cage conductive body including a plurality of conductive bars and a pair of annular conductive end rings provided at both ends of the plurality of conductive bars, the conductive bars extending along a direction in which the rotational shaft is received and being arranged at an outer circumference of the iron core at certain intervals, wherein
- a conductive reinforcing layer extends on at least a part of an outer surface of the conductive end ring, the conductive reinforcing layer being formed by spraying conductive particles in a solid phase onto the outer surface of the conductive end ring.
A manufacturing method for manufacturing a rotor, the rotor comprising:
- a cylindrical iron core having a through hole for receiving a rotational shaft;
- and a squirrel-cage conductive body including a plurality of conductive bars and a pair of annular conductive end rings provided at both ends of the plurality of conductive bars, the conductive bars extending along a direction in which the rotational shaft is received and being arranged at an outer circumference of the iron core at certain intervals, wherein
- the method comprises:
- spraying conductive particles in a solid phase onto at least a part of an outer surface of the conductive end ring so as to form a conductive reinforcing layer thereon.
