Method for detecting sense of rotation on gearbox motor, comprises use of a motor signal with the sense of electricity supply

摘要

An error relative to the sense of rotation is discovered when a direction signal from a sensor over a determined time period does not correspond with a predefined sense of electricity supply to the motor. In the case of brushless motors a series of frequency levels from different sensors may be used to determine the sense of rotation. Independent claims are also included for the following : (1) a coupled or selective gearbox actuator motor which has equipment to study the authenticity of the sense of rotation; and (2) A coupled or selective gearbox actuator motor which has a Hall type sensor whose signals are detected by the equipment to study the authenticity of the sense of rotation.
