Linear Actuator for Rotary Motion Control
|
The linear actuators are integral parts in all manufacturing units. They are used to control rotary motion or excessive vibration in production machines of various commodities. A linear motor also performs the same function. It is usually installed at the base surface of a moving machine and hence, with these you can expect much greater efficiency. Both these devices come with various features and specifications to suit the needs of individual users in the respective industry sectors.
The ones with lesser moving parts are easy to assemble and hence more productive. This is exactly the reason why they are most widely used in various application areas. A linear actuator is generally powered by various energy sources like hydraulic fluids, pneumatic and electric power. Use these devices for the ultimate reduction of shuddering, and increase longevity of machines.
Traits of Quality Linear Motor
All good linear motors should be equipped with appropriate speed, acceleration, and accuracy capability linear motor for high-throughput technology. Only then can you expect the linear actuator to perform effectively in pick-and-place machines, gantry axes, shuttle stages, assembly machines, or in general-purpose positioning. They should also come integrated with the required mechanical and electrical components to eliminate the hassles of choosing bearings, motors, encoders, and the other components required for a linear motor system.
Linear Actuators vs. Hydraulic & Pneumatic Actuators
Good quality linear actuators, unlike the hydraulic and pneumatic varieties are known for being very stable even when you are using them at low speeds. They also offer smoother acceleration and deceleration process. Some of the latest ones can be computer programmed to control the motions at multiple stopping points. Moreover, unlike other motors, the latest linear motor varieties can be programmed to be used for seamless adjustment of position and speed. Even using a stepping motor is easier with these motors. Computer controlling of these devices ensure that setup change is simple, with change only in the data.
Compact Linear Actuators
The compact linear actuators have emerged as the most popular motion control devices these days. Equipped with the best features, they have become the choice of millions of users in various industry sectors. Compact in design, these are known to perform better and allows for greater mobility. These linear actuators help to achieve a significant reduction in the size of your equipment and system. The linear motors of some customized ones also come in a ground ball screw model for higher positioning accuracy.
Remember these points for effective motion control when you wish to get linear actuators for your needs.
