A displacement control motor provided with a rotary shaft (12) and a reel (21) capable of changing deflection angle according to the rotary speed of the motor whereby other articles can be carried, driven, or controlled via the reel. The motor includes a concealed motor (11), a driving gear A, a driven gear B, a reel shaft seat (2) and a load device (3), wherein the rotary shaft is connected with the driving gear while the driven gear meshes with the driving gear. The driving and driven gears (A, B) are both pivoted to the shaft seat (2) and the driven gear is linked with the load device, whereby the rotary shafts of the driving and driven gears are located on the same shaft seat and the driven gear is additionally loaded by the load device (3). A balance spring (22) is used to restrict the displacement of the driven gear so that by means of the change of rotary speed of the rotary shaft, the deflection magnitude of the reel can be controlled. In a toy car, the motor (11) propels the car and the output from the reel (21) actuates the steering mechanism. The motor can also be used in tachometers. <IMAGE> |
