Embodiment Construction

[0029] Below, refer to figure 1 The embodiments of the present invention will be specifically described.

[0030] The present invention is based on a "prototype motor" with a rated frequency of 50Hz (or 60Hz), through an equivalent method, obtains the corresponding "derived motor" parameters, and makes the windings of the "derived motor" according to the parameters of the "derived motor", thereby Obtain the "derived motor".

[0031] Among them, the equivalent method is:

[0032] Based on the parameters of the "prototype motor", the correlation between the "derivative motor" and the "prototype motor" is obtained according to the rule that the amount of copper used in the stator winding wire of the "prototype motor" is equivalent to that of the stator winding wire of the "derived motor" Then multiply the equivalent coefficient by the corresponding "prototype motor" parameter to calculate the corresponding "derivative motor" parameter. Among them, the equivalent coefficient is the pr...

Abstract

A method for producing a ''derived motor'' based on an ''original motor''. Based on the parameters of the ''original motor'' (A), and on the principle that the weight of the copper wires of the stator windings of the ''original motor'' is about equal to that of the copper wires of the stator windings of the ''derived motor'', an equivalent (S) coefficient for relating the ''derived motor'' with the ''original motor'' is obtained. Then the corresponding parameters of the ''original motor'' (A) are multiplied by the equivalent coefficient (S) to obtain the corresponding parameters of the ''derived motor'' (C). Windings of the ''derived motor'' are produced according to the parameters of the ''derived motor'' so as to produce said ''derived motor''. The equivalent coefficient is the product of the factor of the number of windings, the series-parallel connect factor and the Y-delta conversion factor.

Description

Technical field [0001] The invention relates to the field of three-phase asynchronous motors used for frequency conversion and speed regulation, in particular to a method of forming a "derivative motor" from a "prototype motor". Background technique [0002] The "derivative motor" in the name is a concept proposed by the inventor in an invention patent application [application number: 200710039396.0 (hereinafter referred to as A application)] on April 12, 2007. In the application A, the general-purpose three-phase asynchronous motor with a rated frequency of 50Hz (or 60Hz) is called a "prototype motor", and the parameters of the stator winding of the "prototype motor" are designed in a sequenced manner according to certain rules, and calculated Corresponding series of "derived motor" parameters, and then make windings one by one according to these parameters, instead of the stator windings of "prototype motor", a series of new motors can be obtained. Each new motor is called a "...
