Example Embodiment
[0022] The stator core of the permanent magnet motor of this embodiment is formed by stacking a plurality of ring-shaped laminations, and the ring-shaped laminations are a circular ring structure (such as figure 1 As shown, the shaded part is a stator segment), the stator segment is provided with a stator slot 5 with a slot depth of H1, and both sides of the stator slot 5 are provided with triangular cuts for placing slot wedges to prevent the conductor in the stator slot 5 from falling out .
[0023] When in use, the annular laminations are placed in a vertical state. The cuts on the annular laminations include incisions A1, B2, C3 and D4 arranged in the middle of the stator slot 5.
[0024] The radial dimension L of the notch at the notch is: the radial dimension of the notch A1 is greater than that of the notch C3, the radial dimension of the notch C3 is greater than that of the notch B2, and the midpoint of the circumferential length of the stator slot 5 where the notch A1 is lo...
