Servos (also RC servos) are small, cheap, mass-produced servomotors or other actuators used for radio control and small-scale robotics. [citation needed] Most servos are rotary actuators although other types are available. Linear actuators are sometimes used, although it is more common to use a rotary actuator with a bellcrank and pushrod.
A traveling-nut linear actuator has a motor that stays attached to one end of the lead screw (perhaps indirectly through a gear box), the motor spins the lead screw, and the lead nut is restrained from spinning so it travels up and down the lead screw. A traveling-screw linear actuator has a lead screw that passes entirely through the motor.
The SE series and monster trucks featured selectable frequencies within the 27 MHz band for up to six racers along with working headlights and taillights. The SE series had proportional control and used a pistol grip style remote control. Motors, tires and wheel covers (called "hubs") were interchangeable between regular ZipZaps and the SE series.
It started operating in Sweden in 2008 with the purchase of Remote Control. [7] In 2009 the company acquired Flow-Quip, [8] and in 2010 Ralph A. Hillier, US-based businesses. [9] In 2011 Rotork Servo Controles de Mexico S.A. de C.V. became fully owned by Rotork after being part-owned since the 1970s. [10]
A servomotor (or servo motor or simply servo) [1] is a rotary or linear actuator that allows for precise control of angular or linear position, velocity, and acceleration in a mechanical system. [ 1 ] [ 2 ] It constitutes part of a servomechanism , and consists of a suitable motor coupled to a sensor for position feedback and a controller ...
By means of a leadscrew, rotary motion can be adapted to function as a linear actuator (which produces a linear motion, but is not a linear motor). Another broad classification of actuators separates them into two types: incremental-drive actuators and continuous-drive actuators. Stepper motors are one type of incremental-drive actuators.
