The invention mainly relates to a rotary linear permanent magnet electric motor and belongs to the technical field of electric motors. The rotary linear permanent magnet electric motor can simultaneously or independently perform rotary and linear motions. The two types of motions are achieved through a three-dimensionally distributed permanent magnet field. The electric motor can be divided into two types of magnetic circuit structures including a magnetic circuit coupling structure and a magnetic circuit dividing structure. The motor is provided with two independent stators and a hollow active cell, wherein the stators include a stator used for the rotary motion and serving as a rotary stator and a stator used for the linear motion and serving as a linear stator. Two independent non-interfering windings can supply power respectively. The rotary linear permanent magnet electric motor is more convenient to control, easy to achieve and more accurate in positioning, namely the electric motor can perform only-rotary motion, only-linear motion or only-helical motion. In addition, compared with formerly-mentioned linear motors, the number of permanent magnets is small, the electric motor is simple in structure, and the number of poles of the rotation portion and the number of poles of the linear portion need not be equal.
