1. Linear wheel ọsọ ihe mmetụta
Ihe mmetụta ọsọ ụkwụ kwụ ọtọ bụ nke nwere ndọta na-adịgide adịgide, ogwe osisi, eriri induction na ihe mgbanaka. Mgbe mgbanaka mgbanaka na-atụgharị, eze n'elu na azụ azụ na-eche ihu axis pola ụzọ ọzọ. N'oge ntụgharị nke mgbanaka mgbanaka, mgbanaka magnetik dị n'ime eriri induction na-agbanwe ọzọ iji mepụta ike electromotive na-ebute, yana mgbama a bụ ntinye aka na njikwa eletrọnịkị ABS site na eriri na njedebe nke eriri induction. Mgbe ọsọ nke mgbanaka mgbanaka na-agbanwe, ugboro nke ike electromotive a na-ebute na-agbanwekwa.
2. Mgbanaka wheel ọsọ ihe mmetụta
Ihe mmetụta ọsọ wheel nke anular bụ nke mejuputara nke magnet na-adịgide adịgide, eriri induction na ngwa mgbanaka. Ihe ndọta na-adịgide adịgide nwere ọtụtụ ụzọ abụọ nke okporo osisi magnetik. N'oge ntụgharị nke mgbanaka mgbanaka, mgbanaka magnetik dị n'ime eriri induction na-agbanwe ọzọ iji mepụta ike electromotive na-ebute.
