Regarding motor shaft play
Thread Content
Can changes in motor current cause the motor shaft to shift? I invite all the gentlemen to provide answers; I urgently need them
It shouldn’t be possible. . . . . . . . .
It seems you’re talking about two issues... which are theoretically unrelated...
The most likely cause of axial movement of the motor shaft is that the motor rotor does not cut through the magnetic field lines perpendicularly. There are two reasons for this: one is a change in the positioning of the motor bearings, with mechanical energy and electromagnetic energy interacting with each other and resulting in axial movement of the motor; the other reason is abnormal magnetic field lines within the motor itself
Yes, changes in current can cause the magnetic center line to change. Once the magnetic center line stabilizes, the rotor basically stops moving. The movement of the rotor is also closely related to mechanical forces, so a comprehensive consideration is necessary.
The position of the magnetic center line is related to the coil arrangement, right, and it has nothing to do with the magnitude of the total current? Current can only affect the magnitude of magnetic field lines, not their position.
