This invention relates to the field of transverse flux motor technology, and more particularly to a miniature transverse flux motor, comprising a motor housing and an electromagnetic core assembly. The electromagnetic core assembly includes a first stator core, a second stator core, and a magnetic ring disposed between the first and second stator cores. Both the first and second stator cores include several horseshoe-shaped stator blocks arranged in a circular pattern, and each stator core contains a coil winding. The magnetic ring includes a rotor body, a shaft, and permanent magnets. The shaft is coaxially fixed to the center of the rotor body, and the permanent magnets are evenly distributed at equal angles along the circumference of the rotor body. This invention employs a transverse flux structure with upper and lower double stators and a central magnetic ring. During operation, this is equivalent to two motors working collaboratively, significantly increasing the motor's output torque within the constraints of a miniature structure, effectively solving the problem of insufficient torque in existing miniature stepper motors and coreless motors.
