Abstract: To provide a motor capable of preventing a loss due to an excessive leakage current, by increasing the number of poles when comparing to the related art.
A motor 2 includes a cylindrical stator 8 and a cylindrical rotor 9 rotatably provided in the stator 8 coaxially with the center axis of the stator 8 and is used to drive front wheels FW of a vehicle 1 with rotation of the rotor 9. The rotor 9 includes a cage unit 13 including a single short-circuit ring 18 formed in a ring shape and a plurality of secondary conductors 17, and one end portions 17a and the other end portions 17b of the secondary conductors 17 are respectively connected to positions separated in the circumferential direction in the single short-circuit ring 18.

Abstract: According to the present invention, a stator has stator slots and stator teeth. A rotor has rotor slots, rotor teeth, and rotor slot tips projecting in a circumferential direction from the ends in the circumferential direction of the rotor teeth by a prescribed length in a radial direction. The relationship of Nss ≥ Nrs is satisfied, where Nss represents the number of stator slots, and Nrs represents the number of rotor slots. The relationships of Tst ≤ Trt and (Wst - Wrs) + 2 × Dtip ≥ Wst are satisfied, where Wst represents the minimum widths of the stator teeth in the circumferential direction, Wrt represents the average width of the rotor teeth between rotor bars in the circumferential direction, Wrs represents the average width of the rotor slots in the circumferential direction, Tst represents a total of the minimum widths Wst of all the stator teeth, and Dtip represents the length of each of the rotor slot tips in the radial direction.

Abstract: Ein Aktivteil (1) einer elektrischen Maschine (10), weist elektrische Leiter (3,3',3",3"') auf, wobei die elektrischen Leiter (3,3',3",3"') gedruckt sind, wobei zwischen den elektrischen Leitern (3,3',3",3"') ein Zwischenkörper (4,4',4",4"') ist. Bei einem Verfahren zur Herstellung eines Aktivteils (1) einer elektrischen Maschine, werden elektrische Leiter (3,3',3",3"') gedruckt, wobei zwischen elektrischen Leitern (3,3',3",3"') ein Zwischenkörper (4,4',4",4"') gedruckt wird, wobei zwischen dem Druck zumindest eines elektrischen Leiters (3,3',3",3"') und eines Zwischenkörper (4,4',4",4"') abgewechselt wird.
