要想更好的利用开关磁阻电机的功效,首先要掌握它的结构及工作原理,这样才不会不明不白的在操控使用该电机时,发生问题也没有察觉到。因此下面小编就来详细的为大家介绍一下它的结构及工作原理到底是怎样的。  【开关磁阻电机的结构及工作原理】  基本结构:定子和转子均为凸极结构,定子和转子的齿数不等,转子齿数一般比定子少两个。定子齿上套有集中线圈,两个空间位置相对的定子齿线圈相串联,形成一相绕组。转子由铁心叠
In order to make better use of the function of the switched reluctance motor, we must first master its structure and working principle, so that it will not be unclear when the motor is used and the problem is not noticed. Therefore, the following small series will tell you in detail about its structure and working principle.
[Structure and working principle of switched reluctance motor]
Basic structure: Both the stator and the rotor are salient pole structures, and the number of teeth of the stator and the rotor are not equal. The number of teeth of the rotor is generally two less than that of the stator. The stator teeth are sleeved with a concentrated coil, and the two stator teeth coils with opposite spatial positions are connected in series to form a phase winding. The rotor is made up of laminations of iron core with no windings on it.
Working principle: The working principle of the switched reluctance motor is the same as that of the reluctance (reactive) stepping motor, based on the principle that the magnetic flux always closes along the path with the largest permeance. When the center line of the rotor teeth does not coincide and the magnetic conductance is not maximum, the magnetic field will generate a magnetic pull force, forming a reluctance torque, and turning the rotor to the position where the magnetic flux is the largest. When current is sequentially supplied to the stator phase windings, the motor rotor will be rotated step by step in the opposite direction of the energization phase sequence. If the order of energization of the phases of the stator is changed, the motor will change direction. However, the change in the direction of the phase current flow does not affect the steering of the rotor.
Therefore, in general, the stator and rotor of a switched reluctance motor are its main structural devices. Therefore, when maintaining, maintaining, and repairing the motor, these two parts must be carefully maintained, and Xiaobian tells you that many aspects Knowing the knowledge of this motor can help you to better control the use and better and more fully play its role.
