| 摘要 |
The invention relates to a method for manufacturing an electrical machine (1) comprising a housing (2), a stator (3) housed in the housing (2), said stator made up of at least one stator body (19) and stator windings (20), a rotor (4) mounted in the housing (2) rotatably about a rotor axle (5) and a bearing shield (11) attached to the housing (2), wherein the housing (2) is manufactured by manufacturing a housing foam section (22) made up of at least three individual foam parts (23, 24, 25) and by manufacturing a housing casting blank (122) according to a lost foam casting process using the housing foam section (22). In the process, the individual foam parts (23, 24, 25) are made up of a center disc (24) that has a substantially hollow cylindrical shape and that constitutes an intermediate piece of the housing foam part (22), an annular disc (25) that has a substantially hollow cylindrical shape and constitutes another intermediate piece of the housing foam part (22), and a bearing shield disc (23) that has a substantially cupped shape and constitutes an end of the housing foam part (22). The method according to the invention facilitates flexible shaping of the housing (2) of the electrical machine (1) while minimizing the number of tools needed to manufacture the housing foam part (22). |
