SYSTEM AND METHOD FOR DETERMINING THE POSITION OF A MOVING PART DRIVEN BY AN ELECTRIC MOTOR

摘要

A system for determining the position of a moving part driven by an electric motor: a single position sensor, coupled to the electric motor, incrementally detects an amount of movement thereof; a direction switching arrangement controls a direction of movement of the electric motor; and a control unit, coupled to the single position sensor and the direction switching arrangement, at each incremental amount of movement detected by the single position sensor, determines a current position of the moving part based on a previous position thereof and the current direction of movement controlled by the direction switching arrangement.

1. A system for determining the position of a moving part driven by an electric motor, comprising:
a single position sensor, coupled to the electric motor and configured to detect an incremental amount of movement thereof; a direction switching arrangement, configured to control a current direction of movement of the electric motor; and a control unit, coupled to the single position sensor and the direction switching arrangement, and configured, at each incremental amount of movement detected by the single position sensor, to determine a current position of the moving part based on a previous position thereof and the current direction of movement controlled by the direction switching arrangement.
