Embodiment Construction

[0056] Combine below Figure 1 to Figure 5 Specific examples of the present invention will be described in detail.

[0057] see Figure 1 to Figure 2 , taking d=8 as an example, a method for arranging the number of slots in fractional slot windings of single-phase and three-phase motors, including the following steps:

[0058] Step 10, such as figure 1 As shown, arrange the first row list of the fractional slot winding with an equal number of rows and columns:

[0059] The number of rows and the number of columns of the first row list are all defined as d, that is, the first row list is a d row d list; if the first row list includes a complex number group and a plurality of numbers b, the described The number group is composed of c numbers a, wherein a=b+1; the number a and the number b represent the number of slots of the motor, the first number a of the number group is defined as the first number, and the last number a is defined as last number;

[0060] Each row of num...

Abstract

The invention discloses an arrangement method for number of distribution slots in single-phase, three-phase motor fractional-slot windings. The arrangement method comprises the following steps of: calculating the numbers of slots per phase per pole as follows: q =Z / (2p*m); representing q value in the form of a mixed fraction, making b equal to the integer part of q value, c equal to the numerator of the proper fraction in the q value, and d equal to the denominator of proper fraction in the q value, namely q =b+c / d; arranging a first line list and a second line list, then determining the cycle number sequence and the cycle period number k to arrange distribution series of the fractional-slot windings. The arrangement method is simple and easy to understand, convenient to memorize, grasp and use, thus, the arrangement method is completely suitable for the arrangement of frictional-slot double-layer windings, more importantly, particularly suitable for the arrangement of various frictional-slot single-layer windings.

Description

【Technical field】 [0001] The invention relates to a method for arranging the number of slots in fractional-slot windings of single-phase and three-phase motors, in particular to a method for arranging the number of slots in fractional-slot single-layer windings. 【Background technique】 [0002] Low-power motors are characterized by small punches and fewer slots, and are used in single-phase and three-phase low-power motors. In practical applications, multi-pole design and serialization design require general punching, so fractional slot winding problems are often encountered. To design fractional slot windings, it is necessary to sort out the cycle number sequence of the winding distribution, and accordingly to sort out the winding distribution of the entire motor. Fractional slot windings are generally double-layer windings, but for small-power motors, for the convenience of manufacturing, they are also designed as single-layer windings in many cases. The arrangement of wi...
