Abstract
An actuator includes an actuator housing having a first engagement feature and a motor located within the actuator housing and configured to rotate a driver. The actuator also includes a stroke limiting component coupled to the driver and has a second engagement feature. One of the first and second engagement features is a channel and another of the first and second engagement features is a protrusion. The protrusion is configured to fit within the channel to define a stroke of the actuator based at least in part on a length of the channel or a length of the protrusion.
Claims21
An actuator comprising:
- an actuator housing having a first engagement feature;
- a driver;
- a motor located within the actuator housing and configured to rotate the driver;
- and
- a stroke limiting component coupled to the driver and having a second engagement feature,
- wherein one of the first and second engagement features is a channel and another of the first and second engagement features is a protrusion, the protrusion configured to fit within the channel to define a stroke of the actuator based at least in part on a length of the channel or a length of the protrusion.
An actuator comprising:
- an actuator housing;
- a driver;
- a motor internally coupled to the actuator housing and the driver and configured to adjust a position of the driver;
- a circular disk operationally coupled to the motor and configured to rotate in relation to an operation of the motor and the position of the driver, wherein the circular disk comprises one or more markers;
- one or more sensors coupled to the actuator housing and configured to detect a position of the one or more markers;
- and
- an actuator controller operationally coupled to the motor and configured to adjust operation of the motor to adjust the position of the driver, the actuator controller comprising a processor and a memory, the memory storing instructions that, when executed by the processor, cause the processor to perform operations to control an orientation of the circular disk, the operations comprising:
- receiving output actuator orientation data from the one or more sensors based on the orientation of the circular disk;
- determining a rotation distance between an actuator output orientation and a target actuator orientation based on the output actuator orientation data;
- and
- rotating the circular disk based on the rotation distance.
A system comprising:
- an actuator;
- and
- a plurality of interchangeable stroke limiting disks, each stroke limiting disk of the plurality of interchangeable stroke limiting disks configured to be disposed at a face of the actuator and configured to limit a stroke range of the actuator to a different stroke range.
A system comprising:
- an actuator;
- and
- a plurality of interchangeable stroke limiting disks, each stroke limiting disk of the plurality of interchangeable stroke limiting disks configured to couple to a face of the actuator and configured to limit a stroke range of the actuator to a different stroke range, wherein one stroke limiting disk of the plurality of stroke limiting disks comprises:
- a first face having a first channel having a first length configured to limit the stroke range of the actuator to a first stroke range;
- and
- a second face having a second channel having a second length configured to limit the stroke range of the actuator to a second stroke range, wherein the first length is different from the second length.
