Gimbal system

摘要

A gimbal system. The gimbal system may include space-saving features configured to accommodate one or more payload components, thus increasing the payload capacity of the gimbal ball without necessarily increasing the outer dimensions of the gimbal ball. Alternatively, or in addition, the gimbal system may include a motor configured to move at least one gimbal relative to another gimbal about a first axis, with the motor peripherally mounted distal the axis.

1. A gimbal ball, comprising:
an inner gimbal; first and second motor magnets mounted to the inner gimbal; an outer shell rotatably connected around the inner gimbal and extending to the far periphery of the gimbal ball; an intermediate gimbal disposed between the inner gimbal and the outer shell; and first and second motor coils mounted to the outer shell without any intermediate shells separating the first motor coil and second motor coil from the outer shell; wherein the first motor magnet and first motor coil are collectively configured to rotate the inner gimbal relative to the outer shell about a first axis, and the second motor magnet and second motor coil are collectively configured to rotate the inner gimbal relative to the outer shell about a second axis; wherein mounting of the motor coils to the outer shell is configured to facilitate heat transfer away from the first and second motor coils by heat transfer across the shell; wherein the intermediate gimbal is rotatably connected around the inner gimbal, and the outer shell is rotatably connected around the intermediate gimbal; and wherein the first motor magnet and first motor coil are collectively configured to rotate the inner gimbal and the intermediate gimbal relative to the outer shell about a first axis, and the second motor magnet and second motor coil are collectively configured to rotate the inner gimbal relative to the outer shell about a second axis while leaving the intermediate gimbal in a fixed orientation.
