This paper analyzes two adjustment principles for the adjustable magnetic release,namely,gap adjustment and reaction force adjustment.It is shown that the gap adjustment is superior in efficiency and linearity.Thereupon,a practical scheme and its principle are analyzed for the adjustable magnetic release with 3In-11 In range applied to motor protection,and a new implementation scheme is proposed as well.
