Abstract: A strain wave gearing with a built-in motor is provided with a motor, a wave gear mechanism enclosing the motor coaxially, and a heat-insulation spacing formed therebetween. The wave gear mechanism has a wave generator attached to the motor rotor so as to rotate integrally with the motor rotor. A wave generator plug of the wave generator is fixed to a rotor magnet back yoke of the motor rotor so as to enclose the rotor magnet back yoke. The spacing is formed in a contact surface portion between the rotor magnet back yoke and the wave generator back yoke, whereby heat transfer from the motor to the wave gear mechanism is suppressed.

Abstract: A linear DC motor having first and second drive coils and first and second drive magnets arranged in a symmetrical state in relation to a motor central axis that passes through a sliding member in which a lens is mounted. The first and second coils on a moveable side are positioned to both the left and right sides of the sliding member. The first and second drive coils are designed to be independent without being affected by the shape, size, arrangement position, and the like of the sliding member, a linear guide, and a detection part. The first and second drive coils have high rigidity and do not deform when the sliding member slides. Accordingly, it is possible to obtain a linear DC motor that has a highly rigid moveable part and performs positioning action with high responsiveness and high precision.

Abstract translation: 一种具有第一和第二驱动线圈的线性直流电动机，以及相对于通过其中安装有透镜的滑动构件的电动机中心轴以对称状态布置的第一和第二驱动磁体。 可移动侧的第一和第二线圈位于滑动构件的左侧和右侧。 第一和第二驱动线圈被设计成独立的，而不受滑动构件，线性引导件和检测部件的形状，尺寸，布置位置等的影响。 第一和第二驱动线圈具有高刚性并且当滑动构件滑动时不变形。 因此，可以获得具有高度刚性的可动部件的线性直流电动机，并且执行高响应性和高精度的定位动作。
