Thomson ECT 系列 精密线性传动装置

T Series
The proven design of the T series precision linear actuators has found its way into thousands of applications throughout the world. Precision-rolled ball screws provide smooth motion, accurate positioning and quiet operation while the slide guide bushings and the rugged exterior design allows it to be used in the thoughest applications. The T series combines durability, performance and ease-of-use with a large selection of factory-engineered options and accessories. Regardless of the environment or requirement, we can customize our standard models to fit just about any application.

ECT Series
The ECT series is our line of packaged precision linear actuators. They are based on the proven T series and equipped with a high quality selection of motors and gears that make them ready to take on the most demanding applications. The ECT series is ideal when short design times, maximum performance and the longest life cycle are required. And if you can‘t find a standard unit that fits our engineers can build you a customized unit to suit just your needs.

PC Series
The design of a PC-Series™ precision linear actuator delivers extended life, high repeatability, and quiet operation. In addition, it requires minimal maintenance and resists corrosion in harsh environments.

The motor type (if any) of the precision linear actuator.

The manner in which the motor turns the screw inside the unit.

The dynamic load rating is the maximum load the actuator can move at a given speed. The relation between the the dynamic load and the speed can be studied in the speed versus load diagrams. For some actuators however, the column load limit will be exceeded if the extension tube extends beyond a certain point. 

The maximum allowed speed at any given dynamic load ranging from no load to maximum allowed dynamic load. For some actuators however, the critical speed limit can be a limiting factor for the maximum allowed speed if the extension tube extends beyond a certain point.

Brake type, if any.

A resolver is basically a type of rotary electrical transformer used for measuring degrees of rotation and are commonly used on AC servo motors as a feedback device to control the commutation of the motor windings. The resolver is mounted to the end of motor shaft and when the motor rotates the resolver will transmit the position and direction of the rotor to the servo drive which then can control the motor. Most servo drives for AC servo motors on the market today can convert the resolver signal in to a pulse train (encoder signal simulation) which can be used by a motion control to determine and control the position of the motor.

Mounting options to mount the cylinder to the customers machine.

Options for the rod end of the actuator.

How far the cylinder will advance with one full turn of the input shaft or motor.

The magnetic sensors used to the precision linear actuators consist of a reed switch that are molded into a plastic housing. In the actuator a magnet is mounted that travels back and forth with the extension tube. The magnet triggers the magnetic sensors which are mounted on the outside of the cover tube. The sensors come in both normally open and normally closed versions.

The nominal diameter of the screw inside of the actuator.

Roughly the outside cross section dimensions of the actuator cylinder.

The protection class refers to the environmental rating of the enclosure. The first digit applies to airborne contaminants and the second digit to water/moisture. IP65: dust tight and protected against low pressure water jets from any direction.
