A motor controller for an electric vehicle sufficiently reduces vibration components caused by torque ripples passing through a resonance frequency of a vehicle body. The motor controller includes motor torque setting means for generating a first torque command, based on vehicle information, rotation position detection means for detecting a rotation position of the motor, rotation speed calculation means for calculating a rotation speed from a rotation position signal, a high-pass filter that extracts an AC signal component of a rotation speed signal, and a resonance suppression gain circuit that outputs a resonance suppression signal. A signal in which the resonance suppression signal is added to or subtracted from the first torque command is used as a second torque command so as to perform drive control for the motor.
