A method for determining wear of brake pads of an electromagnetically actuable brake, and an electric motor with an electromagnetically actuable brake, and a signal electronics system for carrying out a method of this type, wherein the brake has an energizable coil, wherein, after a voltage is applied to the coil, the time-dependent profile (i(t)) of the electric current which flows through the coil is detected, wherein the values of parameters of a time-dependent function (l(t)) which is parameterized using the parameters are changed, starting from respective starting values of the parameters, until the deviation between the detected current profile (i(t)) and the function (l(t)) becomes as small as possible, that is to say an optimum of the parameters is found, wherein the deviation is formed as a functional of the difference between the function value (l(t)) which is assigned to the respective time (t) and the detected current value (i(t)) or a value which is extrapolated from the detected current values (i(t)), wherein a time (t 1) is determined from the parameters of the optimum as a measure of the wear.
