Abstract
Provided are an electronic seal label apparatus, an electric motor assembly with the electronic seal label apparatus, and an electronic seal label verification method. The electronic seal label apparatus includes: a magnet configured on a first component; and a sensing element configured on a second component and fixed opposite the magnet. When relative motion takes place between the first component and the second component, the sensing element generates a first signal according to the Wiegand effect, so that a disassembly or assembly state between the first component and the second component, which can be removed from each other, can be detected automatically.
