Bi-axial electromagnetic actuator |
摘要 |
A biaxial electromagnetic actuator for a materials testing apparatus comprises a first electromagnetic actuator for imparting a linear force to an output shaft and a second, direct drive electromagnetic actuator for imparting a rotational force to the shaft. The shaft is mounted in two combination bearings which permit the shaft to move axially and rotationally. One of the bearings is located within a hollow cylindrical member which constitutes the armature of the direct drive actuator in order to provide a compact and symmetrical arrangement. |
