Linear actuators are well used in motion control and are a vital device within this field. They usually consist of an AC or DC motor, some form of gearing and a lead or ball screw with driving nut. As the motor turns the screw which forces the nut along the shaft and whatever is being controlled by...

Lead screws are threaded bars of metal and a threaded nut which is in direct contact with the screw; this generates sliding friction as opposed to rolling friction from other alternative devices (such as a ball screw). Rotational motion will turn the screw, causing the nut to move along in a linear...

Servo motors are well suited to precision to applications where accurate control of motor speed,  position and/or torque is required. Advantages of Servo Motors Servo Motors are used throughout many industries and have the following advantages; High efficiency High output power...

Slip rings are a mechanical device that allow the transmission of electrical power and signals from a fixed point to a rotating device and are used to simplify the operation of a system or improve its mechanical performance. Slip rings are used across many industries including construction,...

How does a Direct Drive Motor work? Direct drive motors are either linear or rotary motors and are an integral part of the mechanical assembly. The motors essentially eliminate the need for mechanical transmission elements such as couplings, gearboxes or belt and pulley systems. Direct drive...

How does a Linear Actuator work? Linear actuators work by moving an object or piece of equipment in a straight line, moving an object extremely accurately and repeatably if required. The primary reason for designing a linear actuator into a system is for the need to move a payload in a linear...
