Design of Decelerator in tube-motor

Tubemotor is used n production and daily life as controller of some kinds of coils and curtains. It consists of single phase and asynchronous motor, stop, distant controller and decelerator. Ratio and dimensions in decelerator decide sizes and efficiency of tubemotor. This paper analyzes decelerator′s work on principle and studies design questions for tubemotor. It raises an even load measure to drop uneven load.
