Permanent-magnet engine永磁体发动机是将磁力直接转换成具有转动做功的机械力. The magnetic force of the permanent magnet motor is directly converted into a mechanical force acting with rotation. 转动时不断的改变气隙距离. Constantly changing rotation of the air gap distance. 由δ By δ高明山...
The meaning of PERMANENT MAGNET is a magnet that retains its magnetism after removal of the magnetizing force.
magnet- (physics) a device that attracts iron and produces a magnetic field stud finder- a small permanent magnet in a metal container; when the magnet clicks against the container it indicates that the magnet is directly over an iron nail that holds the wallboard to a stud ...
在通常情况下,与定子的铜损和铁损相比,永磁同步电机中的转子涡流损耗很小。但是由于转子散热条件不好,这些涡流损耗可能会引起很高的温升,引起永磁体局部退磁。 涡流损耗的大小与磁场的变化方式、导体的运动、导体的几何形状、导体的磁导率和电导率等因素有关。
而电枢磁场是电枢电流在电枢绕组周围产生的附加磁场,它会对主磁场产生电枢反应,影响电机的运行性能。 上下两块磁体产生励磁磁场,方向从N->S 一个与励磁磁场垂直的电枢磁场 x是电流流入的方向,o是电流流出的方向,电枢磁场左→右 右手螺旋定则又叫安培定则,是指用右手确定电流方向和由电流引起的磁场及磁感线方向的...
