Can a high-voltage motor change its direction by altering the phase sequence (wiring)? If not, please give the reason.
High-voltage motors can change direction by altering the phase sequence (wiring).
For three-phase asynchronous motors, changing the phase sequence can alter their direction of rotation; as long as the insulation class of the stator windings is suitable, there’s no reason why high-voltage motors cannot have their phase sequence changed.
Synchronous motors cannot be changed; it is not possible to adjust the polarity of the excitation in order to change their direction of rotation. Asynchronous motors, on the other hand, can have their phase sequence changed
As long as it is an AC asynchronous motor, the same principle applies.
