This paper presents a method for calculating the hysteresis loss in a linear dc motor (LDM). The main findings are as follows: (1) under dc bias magnetization, the hysteresis loss of the toroidal pure-iron core increases; (2) under the influence of the dc bias magnetization, the approximate relationship between the hysteresis loss and the maximum magnetic flux density changes from an exponential function to a polynomial one; and (3) the hysteresis loss of the LDM can be calculated from the measured values of the hysteresis loss of the toroidal pure-iron core under dc bias magnetization, and the error of the calculated results is 20.7%.
