查询词典 magnetization current

The intensity of the magnets in permanent-magnet motors can increase as the motor size and output power increase. This causes difficulty in manufacture of large scale PM motors and consequently increases the cost. Post-assembly magnetization can be treated as a solution to the above problem, which fabricates the motors before the magnet is magnetized by applying large current impulse on the motor stator windings.

中文摘要由於永磁马达转子磁铁强度，会随著马达尺寸与输出功率增加而增加，导致大型永磁马达在制作上，因磁铁的强磁性造成组装上的困难，且易有铁粉等杂物附著，使得制作成本增加，故有必要使用新的充磁技术或特殊制程解决。

The magnetic capability of the large dimension toroid for application was measured by the pulse magnetization method. When the outer and inner dimensions of the toroid core were 220 and 80mm, the bight was 60 mm, and the section was 4 200mm^2, the pulse width was 3.5~4.0μs, the repelition rate was 50Hz, the primary and second coils were 1 circle, the maximum volt-second product was 0.007Vs and the bias current was 8A to maintain the toroid not saturated.

使用脉冲法对成型的大尺寸磁环动态磁性能进行测量，励磁方式和工作中完全一致，在测量脉冲脉宽3.5~4.0μs，重复频率50Hz，初次线圈均为1匝，外径220mm，内径80mm，高60mm，截面积4 200mm^2时，得到磁环实际能够达到的伏秒数为0.007Vs，此时所需的偏磁电流大小为8A。

It is the key problem for studying the exciting current in the transformer under DC bias magnetization.

在直流偏磁条件下变压器励磁电流是研究变压器直流偏磁特性的关键。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
