Component for an electric machine
A method of securing a fan member to a rotor assembly of an electric machine. The method includes positioning the fan member adjacent the rotor, aligning at least two mounting members extending radially outwardly of the central hub of the rotor assembly with a corresponding at least two mounting elements extending radially inwardly of a hub portion of the fan member, and securing the at least two mounting members to the corresponding at least two mounting elements.
1. A method of securing a fan member to a rotor assembly of an electric machine, the method comprising:
positioning the fan member adjacent the rotor assembly;
aligning at least two mounting members extending radially outwardly of a central hub of the rotor assembly with a corresponding at least two mounting elements extending radially inwardly of a hub portion of the fan member; and
securing the at least two mounting members to the corresponding at least two mounting elements.
2. The method of claim 1 , further comprising: establishing a gap between the hub portion and the central hub.
3. The method of claim 2 , further comprising: maintaining the gap after joining the fan member with the rotor assembly.
4. The method of claim 1 , wherein securing the at least two mounting members to the corresponding at least two mounting elements comprises staking the at least two mounting members to the fan member.
5. The method of claim 1 , wherein aligning the at least two mounting members with the corresponding at least two mounting elements comprises aligning at least three mounting members with at least three mounting elements.
6. The method of claim 1 , wherein aligning the at least two mounting members with the corresponding at least two mounting elements comprises aligning at least two projections extending outwardly of the central hub with a corresponding at least two notches formed in the fan member.
7. The method of claim 6 , wherein aligning the at least two projections extending outwardly of the central hub with the corresponding at least two notches formed in the fan member comprises aligning the at least two projections with a corresponding at least two notches each having a discontinuous edge formed in the hub portion.
8. The method of claim 7 , wherein aligning the at least two projections with the corresponding at least two notches each having a discontinuous edge formed in the hub portion comprises aligning the at least two projections with a corresponding at least two notches having a curvilinear outer side.
9. The method of claim 8 , wherein aligning the at least two projections with the corresponding at least two notches having a curvilinear edge comprises aligning the at least two projections with the corresponding at least two notches having a semi-circular outer side.
10. The method of claim 1 , wherein aligning the at least two mounting members with the corresponding at least two mounting elements comprises aligning at least four mounting members with a corresponding at least four mounting elements.
