This article presents a simple and nonintrusive method to identify and compensate for current measurement errors in interior permanent magnet synchronous motor (IPMSM) drives. Each IPMSM has a distinct steady-state short-circuit current characteristic. By controlling the motor to operate at its steady-state short-circuit current during coasting down, the inverter can be used to smoothly switch the IPMSM into a three-phase short-circuit state. Then, the $d - q$ axis measured currents are compared with the true short-circuit characteristic of the IPMSM. The distortion pattern in the $d - q$ axis currents contains all the needed information to correct for current sensor errors in IPMSM drives. For a three-phase motor, the proposed method can correct for single-current-sensor error or dual-current-sensor error with good accuracy. The effectiveness of the method is validated by both simulation and experiment.
