All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In order that the above-recited objects, features and advantages of the present invention will become more readily apparent, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description.
Referring to fig. 1, the invention provides a method for determining the number of stator slots and a slot type structure of a variable camera, which comprises the following steps:
step 101, determining a stator slot number range of a three-phase winding and a stator slot number range of a five-phase winding in a target variable-phase stator structure.
Step 102, determining a target arrangement scheme of stator slots in the target variable camera stator structure. The target arrangement scheme comprises a complete shared slot scheme, a partial shared slot scheme and an unshared slot scheme, wherein the complete shared slot scheme is that three-phase windings and five-phase windings are placed in all stator slots in the target variable-phase stator structure, the partial shared slot scheme is that three-phase windings and five-phase windings are placed in part of stator slots in the target variable-phase stator structure, only five-phase windings are placed in part of stator slots, and the unshared slot scheme is that three-phase windings or five-phase windings are placed in all stator slots in the target variable-phase stator structure.
Step 103, determining the number of stator slots in the stator structure of the target variable-phase machine according to the target arrangement scheme, the stator slot number range of the three-phase winding and the stator slot number range of the five-phase winding.
And 104, determining the groove type of the stator groove in the target variable camera stator structure according to the number of the stator grooves in the target variable camera stator structure. The slot type of the stator slot includes the size of the stator slot.
The method for determining the number of stator slots and the slot type structure of the variable camera can convert the three-phase power supply of the variable camera into a five-phase power supply, and generate induced electromotive force in the five-phase winding by energizing three phases in the three-phase winding. And then directly supplying power to the five-phase propulsion motor through a five-phase power supply.
Further specifically, step 101 specifically includes:
The stator slot number range of the three-phase winding is determined according to the formula Q 1＝6p1q1, where Q 1 is the stator slot number range of the three-phase winding, p 1 is the pole pair number of the three-phase winding, and Q 1 is the slot number range per pole per phase of the three-phase winding.
The stator slot number range for the five-phase winding is determined according to equation Q 2＝10p2q2, where Q 2 is the stator slot number range for the five-phase winding, p 2 is the pole pair number for the five-phase winding, and Q 2 is the slot number range per pole per phase for the five-phase winding.
In one example, referring to fig. 2 to 5, the number of slots of the stator slots in the target variable-phase stator structure is determined according to a target arrangement scheme, a stator slot number range of the three-phase winding 2, and a stator slot number range of the five-phase winding 1, and specifically includes:
Referring to the embodiment of fig. 2, fig. 2 shows a stator slot number structure when the number of poles of the variable phase is 4, the number of slots per phase of each pole of the three-phase winding is5, and the number of slots per phase of each pole of the five-phase winding is 3, and two sets of windings share the slot 3. When the target arrangement scheme is the complete shared slot scheme, the least common multiple of the stator slot number of the three-phase winding 2 and the stator slot number of the five-phase winding 1 is obtained according to a stator slot number formula and is used as the slot number of the stator slots in the stator structure of the target variable camera, and the stator slot number is at least the least common multiple of 6 and 10, namely the least common multiple of the stator slot number is 30 or 30.

When the target arrangement scheme is a partial common slot scheme, the number of slots of the stator slots in the target variable camera stator structure is determined according to the number of stator slots range of the five-phase winding 1 because the three-phase winding 2 occupies only a part of stator slots in the target variable camera stator structure, i.e. the number of stator slots range of the five-phase winding 1 is larger than the number of stator slots range of the three-phase winding 2.
Referring to the embodiment of fig. 5, fig. 5 shows a stator slot number structure with a variable phase number of 2 poles, a three-phase winding number of 5 slots per phase per pole, and a five-phase winding number of 3 slots per phase per pole when two windings do not share slots.

It is possible to design the stator slots of the two sets of windings separately and to combine the stator slots of the two sets of windings together. At the moment, the stator slot number of the three-phase winding 2 is determined according to the stator slot number range of the three-phase winding 2, the stator slot number of the five-phase winding 1 is determined according to the stator slot number range of the five-phase winding 1, and the sum of the stator slot number of the three-phase winding 2 and the stator slot number of the five-phase winding 1 is determined as the slot number of the stator slot in the stator structure of the target variable camera.

When the target arrangement scheme is a partial common slot scheme, the number of the common slots 3 is determined according to the number of slots of the stator slots, the number of the three-phase windings 2 and the number of the five-phase windings 1 in the target camera stator structure, the size of the common slots 3 is larger than the size of the stator slots 4 except for the common slots according to the condition of the winding carrying capacity, the number of the common slots is the number of the stator slots shared by the three-phase windings 2 and the five-phase windings 1, the size of the common slots 3 and the size of the stator slots 4 except for the common slots are not limited herein, and suitable sizes can be selected according to actual needs.
