對(duì)于低壓大功率電機(jī)，為了獲得適宜的通電截面，往往需要多根電磁線進(jìn)行并聯(lián)，同時(shí)，電機(jī)繞組的引接線部分，為了規(guī)避電機(jī)物理空間的局限性，以及電機(jī)接線、繞組絕緣處理過(guò)程可能涉及到的質(zhì)量問(wèn)題，也會(huì)通過(guò)多根較細(xì)導(dǎo)電直徑的引接線進(jìn)行關(guān)聯(lián)。問(wèn)題來(lái)了，并聯(lián)的引接線如何與并繞的電磁線進(jìn)行連接？如何保證連接后繞組及引接線的正常運(yùn)行？這是一個(gè)非常關(guān)鍵和重要的設(shè)計(jì)和工藝控制環(huán)節(jié)。
從簡(jiǎn)單的物理知識(shí)我們可以分析，只有將每一相多股并繞的電磁線均勻地分配給多根的電機(jī)引接線，且保證每一個(gè)連接部位都可靠，才能有效保證電機(jī)繞組性能的正常運(yùn)行，任何分配的不均勻，以及頭尾分配的不一致性，都可能導(dǎo)致引接線及電磁線電流密度的不均勻，出現(xiàn)繞組或引接線發(fā)熱的不良后果。
For low-voltage high-power motors, in order to obtain a suitable cross-sectional area, multiple electromagnetic wires are often required to be connected in parallel. At the same time, in order to avoid the limitations of the physical space of the motor and the quality issues that may be involved in the motor wiring and winding insulation treatment process, the connection of the motor winding's lead wire is also linked through multiple lead wires with finer conductive diameters. The question is, how can parallel lead wires be connected to parallel wound electromagnetic wires? How to ensure the normal operation of the connected winding and lead wire? This is a crucial and important design and process control process.
From simple physical knowledge, we can analyze that only by evenly distributing each phase's multi stranded electromagnetic wire to multiple motor leads, and ensuring that each connection is reliable, can the normal operation of motor winding performance be effectively guaranteed. Any uneven distribution, as well as inconsistency in head and tail distribution, may lead to uneven current density in the leads and electromagnetic wires, resulting in adverse consequences such as heating of the windings or leads.
