Abstract
В заявке описан электромагнитный датчик положения и способ определения положения вращающегося тела. Электромагнитный датчик положения включает вращающийся элемент, конструкция которого позволяет ему быть соединенным в рабочем положении с вращающимся телом. Вращающийся элемент имеет первую немагнитную корпусную часть и множество магнитов, равноудаленных друг от друга на внешней части первой немагнитной корпусной части. Электромагнитный датчик положения также содержит узел статора, содержащий вторую немагнитную корпусную часть с отверстием, проходящим сквозь нее и служащим для размещения вращающегося элемента. Стартер также включает множество витков обмотки и множество креплений для витков обмотки. Каждый виток из множества витков обмотки закреплен на соответствующем креплении из имеющегося множества креплений для витков обмотки. Крепления для витков обмотки прочно зафиксированы на равном расстоянии друг от друга на второй немагнитной корпусной части. За счет вращения вращающегося элемента витками обмотки генерируются сигналы напряжения, которые указывают на положение вращающегося элемента.
