A stepping actuator having a housing containing two linearly reciprocating members independently and axially slidable, and a common rotating member passed through them. One of the housing and linearly reciprocating members has endless circulating grooves formed by tilted grooves interconnected by circumferentially extending grooves while another one of them holds projections adapted to fit in the circulating grooves. The circumferentially extending grooves have a circumferential length equal to ...

A stepping exerciser, which includes a base frame having an upright support and two horizontal pivots at two opposite sides of the upright support, a damping mechanism mounted on the upright support at the top, the damping mechanism having two cranks disposed at two opposite sides and rotated to impart a damping force, two pedals respectively turned about the horizontal pivots at the upright support, the pedals each having a front end provided with a pivot hole and a rear end provided with a foo...

A stepping exerciser including a base frame, an upper support, a stepping device, a front stem, a rear seat stem and a damper. When two pedal levers of the stepping device are alternately stepped up and down, the pushing arms under the pivot tubes of the pedal levers drive the linkages to alternately swing back and forth. At this time, the driving rods under two sides of the rotary discs are driven to rotate the rotary disc. Responsively, the handle bar connected with upper end of the front stem...

A stepping motor that facilitates separate winding of annular bobbins of annular stator cores while preventing current-carrying terminals from acting as a bar to the winding work is provided. The stepping motor includes first and second annular stator cores (4, 5) having respective annular bobbins (42, 52) wound with first and second exciting coils (41, 51) around winding sections (45, 55), respectively, and a rotor (3) having a rotation shaft (32) within a concentrical lamination structure of t...
