Description

  The present invention relates to a kind of stator coil set for an electric motor or a generator, and in particular, is a centralized winding structure in which coil winding structures are combined with a separate irregular columnar conductor, which is used instead of the well-known coil conductor continuous winding method. In addition, the coil groove size is adjusted to the shape of the irregular columnar conductor in the coil groove to greatly increase the groove ratio of the conductor in the coil groove, and thereby the bending when the conducting wire in the coil set advances into the coil groove. It is applied to motors or generators that prevent operation, especially high power and difficult to multi-pole winding, and in multi-pole stator structure, the difficulty of winding is reduced and the groove spacing ratio is increased, and at the time of high current output The present invention relates to a stator coil set for an electric motor or a generator that reduces copper loss.

  An electric motor or generator with a concentrated coil set design has better output efficiency, output power, and heat dissipation capability than an electric motor or generator with a distributed coil set design under the same volume. However, when the traditional coil conductor performs a winding operation, if the conductor is not bent by 180 degrees, it cannot enter from one coil groove to another coil groove. For this reason, as the conductor cross-sectional area increases, the number of stator poles increases. The number of windings becomes difficult and the cost of the winding becomes high, and the conductor having an excessive cross-sectional area cannot perform the bending operation.

  However, when a large power output is required for an electric motor or generator, the first thing to consider is the cross-sectional area of the conductor wire, because when a large current flows through the conductor, the copper loss formed by that resistance is very In other words, if the design is not appropriate, the lead wire burns out and forms a short circuit, which creates a danger. For this reason, all high-power motors or generator stator coils increase the cross-sectional area of their coil conductors to reduce resistance and reduce copper loss at the time of large current output of the motor or generator. .

  For this reason, electric motors or generators with a concentrated coil set design are limited to the difficulty and high cost when conducting a wire with a large-area conducting wire, and are currently only used in facilities or electric devices with low power output.
