Abstract: Disclosed is a realization method of a speed signal of a motor using a linear Hall-effect sensor that may include the steps of: determining coordinate values on a x-y coordinate system using a Hall signal in the form of a sine wave of a linear Hall-effect sensor, evaluating a summed coordinate value of the above coordinate values, calculating the angle (?) formed by a summed coordinate value and the x axis; determining the quadrant of the resulted angle (?), and determining a speed signal by dividing the final motor displacement value by the rate of time change.

Abstract: Disclosed is a realization method of a speed signal of a motor using a linear Hall-effect sensor characterized by comprising the steps of: by using a Hall signal in the form of a sine wave of a linear Hall-effect sensor, determining coordinate values on a x-y coordinate system of the position sensor; evaluating a summed coordinate value of the above coordinate values; calculating the angle(?) formed by a summed coordinate value and the x axis; determining the quadrant of the resulted angle(?); and determining a speed signal by dividing the final motor displacement value by the rate of time change.
