Sectional torque motors are unique motion components that can be used to control or move elements that only require limited rotation. These devices provide very linear torque and high acceleration. They are ideal for limited movement applications where space is critical, no room for a full sized round motor.
Since the angle of rotation is limited, these motors require no commutation, which makes the design brushless, regardless of the excitation method used. The brushless design means that there is no brush wear debris to contend with in applications where cleanliness is an issue.
These devices are supplied as a parts-set and are intended to use existing structures as their supporting elements. This concept reduces the total mass of the complete assembly by eliminating redundant support structures and reduces total system cost.
Benefits
Saves physical space Ripple free operation Less friction Better heat dissipation Winding is on the outside element, namely the stator No cogging Two leads: simpler electronics Excellent form-factor: allows for use in very tight volume Integrate feedback devices

受限的旋轉電機剖轉矩電機是可用於控製或動議隻需要有限的轉動元件獨特運動分量。這些設備提供了非常線性的扭矩和高加速度。他們是理想的運動受限空間應用的關鍵，容不得一個全尺寸的輪馬達。
自的旋轉角度受到限製，這些馬達不需要換嚮，這使得設計無刷，無論使用的激勵方法的。無刷設計意味著冇有刷磨屑抗衡的應用中清潔度是一個問題。
這些裝置被提供作為一個部件集，並且意為使用現有的結構作為其支撐元件。這一概念通過消除冗餘支撐結構降低了整個組件的總質量，並降低係統成本。
優點
節省物理空間 紋波自由運作 少一些摩擦 更好的散熱 繞組是在外麵元件，即定子上 無齒槽 兩個線索：簡單的電子産品 出色的外形：允許使用在非常緊卷 集成反饋裝置
