Technical solutions are described herein for position estimation of permanent magnet synchronous machines through vibration induced saliency. An example permanent magnet synchronous machine (PMSM) includes a motor control system to provide input command to the motor to cause a position of the motor to change. The PMSM further includes a motor position estimation module configured to estimate the position of the motor. The estimation includes measuring a current Iabc across the motor. The estimation further includes extracting a filtered current Iabc_inj at a predetermined frequency from the current Iabc. The estimation further includes estimating the position of the motor based on the filtered current Iabc_inj.
