Device Electromechanical wheel brake.

Device electromechanical wheel brake, with an electric motor (18) comprising a rotor (20) annular gear (48) converting rotation-translation operable rotatably to the motor (18) power, and a liner (14) friction brake which can be pressed by the gear (48) converting rotation-translation against a body (16) brake, wherein said electric motor (18) is configured as motor (18) transverse flow a coil (22) annular exciting surrounding an imaginary axis of the motor, wherein the motor (18) electrical number of yokes (24) are arranged distributed over the circumference of the winding (22) excitation and can be excited with it, and a number of poles (30) which preferably matches the number of yokes (24) driven such that they can move together with respect to the yokes (24) in a circular path in the circumferential direction of the yokes (24) and can be magnetically attracted to achieve a circular by exciting the yokes (24) movement.
