EP0202011A3 Torque motors and valve assemblies 失效
标题翻译：扭矩电机和阀组件

申请号：EP86302506

摘要： A torque motor is arranged at each end of a common shaft, e.g. for driving a servo valve. The motor comprises a rotor and a stator. Preferably, the rotor carries at least one pair of samarium cobalt permanent magnets at radially spaced positions, the core material being disposed between the magnets. Such a motor can be relatively compact whilst producing a high torque.
摘要翻译：扭矩马达设置在公共轴的每个端部，例如用于驱动伺服阀。电动机包括转子和定子。优选地，转子在径向间隔的位置处承载至少一对钐钴永磁体，芯材设置在磁体之间。这样的电动机可以相对紧凑，同时产生高扭矩。

摘要： An electrohydraulic servo valve (10) comprises a pair of electric motors (11) mounted on the body - (13) of a linear hydraulic spool valve (12) and driving a common motor shaft (77) whose rotation is transmitted directly to the valve spool (20) by a pivoted lever (90), one end of which is engaged in a cross-bore (89) in the motor shaft (77) and the other end of which is engaged in a cross-bore (30) in the valve spool (20). The lever (90) is pivotally suspended by two integral rectangular-section thin steel strips projecting at right angle from opposite sides of the lever and secured by screwed-down integral mounting blocks (107) at their outer ends. The strips are arranged with their widths transverse to the length of the lever (90), and twist resiliently about their lengths as the lever pivots about a pivotal axis (92) coincident with the lengths of the strips (105,106) providing a frictionless pivotal suspension for the lever with a resilient centering action.
