Abstract

The invention provides a motor, which can prevent spending time in restoring motor inherent information like error information of installation position of a rotor position detecting element even if the motor or control device are exchanged and the mutual combination is released. The motor (20) comprises a rotor (22), a position detecting element (63) used for detecting the position of the rotor (22), a storing part (80) used for storing motor inherent information which can be output to the outer part of the rotor (22) or storing error information of the installation position of the position detecting element (63). The error information of the installation position of the position detecting element (63) can be stored in the motor (20) itself by means of the storing part (80) without storing error information of the installation position of the position detecting element (63) in the control device (60) of the motor (20).

Description

technical field [0001] The present invention relates to an electric motor and a moving body of an electric vehicle equipped with the electric motor, wherein the electric motor is provided with a position detection element for detecting the position of the rotor required for the operation control of the electric motor. In addition, the present invention also relates to a method for storing error information of an installation position of a position detection element of a rotor. In addition, in the description of the present invention, "information indicating an error" is simplified and may be described as "error information". Background technique [0002] Conventionally, an automatic vehicle or an automatic two-wheeled vehicle has generally used an engine that uses gasoline or light oil as fuel to obtain driving force as a driving source. However, recently, as a measure for environmental protection, the development of an electric vehicle using an electric motor that obtains ...
