Abstract

PROBLEM TO BE SOLVED: To provide a roller device with power functions. SOLUTION: A slender type shaft motor with an outer rotary type motor linked to a shaft has at least one roller unit which is provided with a fixed shaft rod. The fixed shaft rod has one coil stator set which is provided with a plain steel plate stators each wound with a coil. A cylindrical magnet set is arranged outside the coil stator set corresponding thereto and magnets are disposed in the magnet set with the one adjacent thereto placed eccentric in the axial direction thereof. An axial clamp device composed of a bearing and an outer lid of the bearing is placed at both ends of the magnet set. As a result, a roller unit is formed with a difference between a gap of the magnets and a gap of the plain steel plate stators in the axial position while after the electric energization of the coil stator set, the magnet set turns around the coil stator set. Thus, with power functions thus obtained, the roller device is applicable for matters to match wider different purposes.

As a result, after the motor 205 is activated, the front roller 202 is driven and rotated, and the front roller 202 further drives the belt 201 and the movement thereof causes the rear roller 2 to move.
Drive 03 to rotate. This shows that the walking machine 200 uses the motor 205 as a power source, and directly drives the front roller 202 and then further drives the belt 201 and the rear roller 203 by using frictional force. If the walking machine 200 has a total length of 1.8 meters, the length of the sidewalk is about 1.5 meters, and the rest is left in the space of the motor 205 which is the only power source. , Requires a motor with a large horsepower number, and generally the size of the motor volume is directly proportional to the horsepower number. Therefore, the longer the sidewalk, the more it is necessary to increase the motor horsepower. Therefore, the larger the motor volume, The mounting position required on the motor walking machine also became large, occupying a space and causing a problem of inconvenience.
