Motor sensor, rotating speed and position measuring method and device and medium

Abstract

The embodiment of the invention provides a motor sensor, a rotating speed and position measuring method and device and a computer readable storage medium, and belongs to the technical field of sensors. The sensor comprises a main coil disc used for fixing a main coil, and the position of the main coil disc relative to a shell of the motor is fixed; the N main coils are fixed on the main coil disc, and N is an integer greater than or equal to 3; the secondary coil panel is arranged on a rotating shaft of the motor and rotates synchronously with the rotating shaft of the motor; two secondary coils fixed to the secondary coil panel; and the N current sensors are respectively connected with the N main coils and are used for measuring the current in the N main coils. The sensor can determine the rotating speed of the motor and/or the position of the rotating shaft according to the current of the main coil. 本公开的实施方式提供了电机传感器、转速和位置测量方法及装置和计算机可读存储介质，属于传感器技术领域。传感器包括：主线圈盘，用于固定主线圈，相对于电机的外壳的位置固定；N个主线圈，固定于主线圈盘，其中N是大于等于3的整数；副线圈盘，布置在电机的转轴上，与电机的转轴同步转动；2个副线圈，固定于副线圈盘；N个电流传感器，分别与N个主线圈中的主线圈连接，用于测量N个主线圈中的电流。本公开的传感器可以根据主线圈的电流可以确定电机的转速和/或转轴位置。
