device and method for correcting phase error of resolver

The resolver phase error correction apparatus and method is disclosed. Resolver phase error correction apparatus includes a command for outputting a torque command signal to stop after rotating the rotor by a predetermined phase angle of the motor output signal; A phase of calculating the phase error value in advance using the difference for a given rotor phase gakgan to correspond to the resolver phase angle and the torque command signal corresponding to the sensing signal of the torque made by the command signal sensing the rotation of the rotor resolver error calculating unit value; And by reflecting the phase error value to the resolver phase angle corresponding to the sensed signal of the resolver it is input during operation of the motor and a controller for recognizing the rotor phase angle. According to the invention, the resolver is the by detecting the resolver and the rotating phase error between e (that is, an average of one phase between the resolver and the rotor mismatch) the easy way more, even though they are mounted in place, and compensate the motor It can generate the maximum output.
