Coreless uses a no core rotor , that breaks the traditional motor with the structure of motor rotor . Thus , it is also called the coreless motor . Because of the loss of electricity caused by the eddy current . Using coreless motor can reduces its weight and moment of inertial , thereby we get less loss of mechanical energy . Changes of rotor structure make better movement of a motor , and it also leads to a prominent Energy-saving characteristic , most important of that , it has the control characteristic and drag characteristic that others can never realize . The tail cover of coreless motor has a large affect on the motor movement stability. This content concentrate on the machine designing, including designing of the tool, chuck, chuck sleeve and a connector. Also I choose a cylinder that can satisfy the task needs and an appropriate mean for cylinder control is resolved . In order to guarantee the stability of assembly, a buffer device is designed to improve the assembly yield .Finally I also have a PEA test on some important parts of the machine to make sure that this device can proper functioning. KEYWORDS: Tail cover of the coreless motor ；Assembly device ；PEA . 目　录 TOC \o "1-3" \h \z \u HYPERLINK \l "_Toc292955204" 摘要 PAGEREF _Toc292955204 \h II H
