A motor comprising: a rotor supported for rotation about a longitudinal axis; a stator including a magnetic core; a first end plate positioned at a first end of the magnetic core; a second end plate positioned at a second end of the magnetic core, the magnetic core, the first end plate, and the second end plate cooperating to define a central opening, at least a portion of the rotor disposed within the central opening; a plurality of rods (50, 50a, 50b), each rod fixedly attached to the first end plate and the second end plate and including a first end that extends parallel to the longitudinal axis beyond the first end plate in a direction away from the magnetic core and a second end that extends parallel to the longitudinal axis beyond the second end plate in a direction away from the magnetic core; a first support disk (60, 60a) coupled to the first end of each of the plurality of rods (50, 50a, 50b) such that the first support disk is spaced apart from the first end plate; and a second support disk (60, 60a) coupled to the second end of each of the plurality of rods (50, 50a, 50b) such that the second support disk is spaced apart from the second end plate, wherein each of the plurality of rods includes a length (300, 305), the length measured between a first end fixedly attached to the first support disk and a second end fixedly attached to the second support disk, a cross-sectional shape, a cross-sectional area, and a stiffness that cooperate to define a natural frequency, and characterized in that the length of one of the plurality of rods is different from the length of another of the plurality of rods. a rotor supported for rotation about a longitudinal axis; a stator including a magnetic core; a first end plate positioned at a first end of the magnetic core; a second end plate positioned at a second end of the magnetic core, the magnetic core, the first end plate, and the second end plate cooperating to define a central opening, at least a portion of the rotor disposed within the central opening; a plurality of rods (50, 50a, 50b), each rod fixedly attached to the first end plate and the second end plate and including a first end that extends parallel to the longitudinal axis beyond the first end plate in a direction away from the magnetic core and a second end that extends parallel to the longitudinal axis beyond the second end plate in a direction away from the magnetic core; a first support disk (60, 60a) coupled to the first end of each of the plurality of rods (50, 50a, 50b) such that the first support disk is spaced apart from the first end plate; and a second support disk (60, 60a) coupled to the second end of each of the plurality of rods (50, 50a, 50b) such that the second support disk is spaced apart from the second end plate, wherein each of the plurality of rods includes a length (300, 305), the length measured between a first end fixedly attached to the first support disk and a second end fixedly attached to the second support disk, a cross-sectional shape, a cross-sectional area, and a stiffness that cooperate to define a natural frequency, and characterized in that the length of one of the plurality of rods is different from the length of another of the plurality of rods.
