2. Rotary actuator - Wikipedia

   en.wikipedia.org/wiki/Rotary_actuator

   A rotary actuator is an actuator that produces a rotary motion or torque. The simplest actuator is purely mechanical, where linear motion in one direction gives rise to rotation. The most common actuators are electrically powered; others may be powered pneumatically or hydraulically, or use energy stored in springs.

3. Valve actuator - Wikipedia

   en.wikipedia.org/wiki/Valve_actuator

   Electric actuator (blue cylinder) on a valve in a power plant. A black handwheel is visible on the actuator, which allows manual positioning of the valve. The blue valve body is visible in-line with the pipe. The valve actuator opens or closes the butterfly disc of the valve based on electrical signals sent to the actuator.

4. Actuator - Wikipedia

   en.wikipedia.org/wiki/Actuator

   Electric rotary actuators use a rotary motor to turn the target part over a certain angle. [11] Rotary actuators can have up to a rotation of 360 degrees. This allows it to differ from a linear motor as the linear is bound to a set distance compared to the rotary motor.

5. Linear actuator - Wikipedia

   en.wikipedia.org/wiki/Linear_actuator

   A traveling-screw linear actuator has a lead screw that passes entirely through the motor. In a traveling-screw linear actuator, the motor "crawls" up and down a lead screw that is restrained from spinning. The only spinning parts are inside the motor, and may not be visible from the outside. Some lead screws have multiple "starts".

6. Massage chair - Wikipedia

   en.wikipedia.org/wiki/Massage_chair

   Traditional massage chair. A massage chair is a chair designed for massages. It can refer to two types of products. Traditional massage chairs allow a massage therapist to easily access the head, shoulders, and back of a massage recipient, while robotic massage chairs use electronic vibrators and motors to provide a massage.

7. Motorized wheelchair - Wikipedia

   en.wikipedia.org/wiki/Motorized_wheelchair

   A motorized wheelchair, powerchair, electric wheelchair, or electric-powered wheelchair (EPW) is a wheelchair that is propelled by means of an electric motor (usually using differential steering) rather than manual power. Motorized wheelchairs are useful for those unable to propel a manual wheelchair or who may need to use a wheelchair for ...

8. Lift table - Wikipedia

   en.wikipedia.org/wiki/Lift_table

   Lift tables can also be driven by pneumatic sources, trapezoidal-threaded screw drives, push chains or by hydraulic foot pump when the load is not heavy. The choice of drive mechanism depends on factors such as load capacity, lifting height, speed requirements, and the intended environment. Lift tables can be mounted in a pit for floor-level ...
