Motor having two degrees of free motion |
摘要 |
A motor having two degrees of free motion includes: a motor casing; a combined core of cylindrical shape having a plurality of inner teeth inside and a plurality of outer teeth outside and fixedly coupled inside the motor casing; a first coil winding wound on the inner teeth of the combined core; a second coil winding coil wound on the outer teeth of the combined core; a rotating armature having a permanent magnet inside inserted inside the combined core and rotated by an interaction of a magnetic flux formed by the first coil winding and the permanent magnet; a linear armature located at one side of the second coil winding undergoing a linear movement by the flux formed by the second coil winding; a driving shaft penetratingly coupled to the rotating armature and to the linear armature and undergoing rotating and linear movements therewith; and a spring urging the linear armature away from the combined core. The motor is not only able to generate a linear reciprocating driving force and a rotating force at the same time, but is also able to generated one force between the two selectively, whereby only one motor can be used for a system which needs the linear movement and the rotating movement, and the system is constructed in a simple way because no additional motion translation device is needed.
