aluminium Magnet wire also has corresponding application scenarios, the following is the introduction of aluminum wire motor:
(The resistivity at any temperature can be calculated with the [Resistance Temperature Rise Conversion Tool] function in the software) For a micro motor with a particularly small power, the efficiency is improved, and it is very likely that the test will pass in winter and fail in summer. This product can only be used in winter and should be paid attention to.
If the calculation efficiency of the software default value is very low, but the efficiency in the actual test is very high, it is necessary to check whether it is a problem caused by temperature. Another possibility of inaccurate calculation of winding copper loss is that the actual wire package length differs greatly from the software calculation.
Process of aluminum wire motor:
The length of the wire package is related to the wire die size and process. If you want to calculate it accurately, it is best to input this data by the user. However, considering that the software automatically calculates the value in most cases, it can basically be consistent with the actual situation. The software does not leave this input item. It may cause calculation errors in some micro motors with many turns.
If there is a significant deviation between the calculated wire package weight and the actual weight, you can modify the resistivity to make the winding resistance calculation accurate, and modify the density to make the winding weight calculation accurate. Of course, this is an indirect correction calculation. In fact, it is because the software's algorithm for automatically calculating the length of the thread package does not match the actual calculation. This situation is very rare.
