The invention provides a motor control optimization method and device and a motor controller, and relates to the technical field of motor control, and the method comprises the steps: presetting a plurality of given direct currents of different types of motors, and controlling each type of motor to rotate under each given direct current, so as to obtain a zero offset value of each type of motor under each given direct current; target direct currents corresponding to all types of motors are determined from all the given direct currents according to a preset zero offset reference value, and the error of a zero offset value determined under the target direct currents relative to the zero offset reference value is minimum; the target direct current corresponding to the working motor is obtained according to the type of the working motor, zero offset control is performed on the working motor under the target direct current, and the problem that an existing motor is large in zero offset error is solved. 本发明提供一种电机控制优
