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

Provides a consistent torque over a limited angle
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

受限的旋转电机

剖转矩电机是可用于控制或动议只需要有限的转动元件独特运动分量。这些设备提供了非常线性的扭矩和高加速度。他们是理想的运动受限空间应用的关键，容不得一个全尺寸的轮马达。

自的旋转角度受到限制，这些马达不需要换向，这使得设计无刷，无论使用的激励方法的。无刷设计意味着没有刷磨屑抗衡的应用中清洁度是一个问题。

这些装置被提供作为一个部件集，并且意为使用现有的结构作为其支撑元件。这一概念通过消除冗余支撑结构降低了整个组件的总质量，并降低系统成本。

优点

提供了一个有限的角度一致的力矩
节省物理空间
纹波自由运作
少一些摩擦
更好的散热
绕组是在外面元件，即定子上
无齿槽
两个线索：简单的电子产品
出色的外形：允许使用在非常紧卷
