A rotary transformer is generally installed on a permanent magnet synchronous motor for a new energy automobile and used for analyzing the position of a motor rotor, and a motor controller calculates the accurate magnetic pole position of the rotor by decoding the position of the rotor and a rotary transformation initial angle value prestored in a built-in program of the rotor, so that the closed-loop accurate control of the permanent magnet synchronous motor is realized. The initial angle of the rotary transformer is a deviation angle between a zero angle of the rotary transformer and a zero angle of the permanent magnet synchronous motor, and is also called as a zero initial angle of the motor, and is usually determined after the rotary transformer is installed.
