Innovative Motion Control ABOUT ETEL LINEAR MOTORS What is a linear motor? Over the last 20 years, direct drive linear motors have provided significant performance improvements in numerous applications covering a wide range of high-tech industries. Today, direct drive technology is recognized as a leading solution towards meeting the requirements of high productivity, improved accuracy, and increased dynamics of modern machinery. Linear motors are a special class of synchronous brushless servo motors. They work like torque motors, but are opened up and rolled out flat. Through the...

Innovative Motion Control WHY ADOPT LINEAR MOTORS? Reduced cost of ownership Direct coupling of the payload to the moving part of the motor eliminates the need for mechanical transmission elements such as leadscrews, timing belts, rack and pinion, and worm gear drives. Unlike brushed motors, in a direct drive system there is no contact between the moving parts. Therefore there is no mechanical wear, resulting in excellent reliability and longevity. Fewer mechanical parts minimize maintenance and reduce the system cost. The direct drive technology results in an efficient and effective...

Innovative Motion Control LINEAR MOTORS Linear motors range During the last two decades, many linear motor variations have emerged on the market. Nevertheless, only a few were found to be practical, perform well and economically viable. ETEL has always remained dedicated to the flat, synchronous, 3-phase linear motors with permanent magnet excitation. This family of motors represents more than 90 percent of industrial applications worldwide. They can be classified into ironcore and ironless motors. ETEL offers the most comprehensive standard linear motor range in the industry. With more...

Innovative Motion Control DIRECT DRIVE SOLUTION Encoders To achieve optimum performance from a direct drive motor, it must be built to the necessary standards of precision and stiffness as part of a complete direct drive solution. In addition to the motor, the main key components of a direct drive system are the controllers, encoders, bearings and machine structure. Direct drives place rigorous demands on position-signal quality. Optimum measuring signals increase the quality of the machined workpiece surface, reduce vibration in the machine frame, stop excessive noise exposure from...

Innovative Motion Control LINEAR MOTOR SELECTION Motor constant Many factors must be taken into consideration when choosing a linear motor to ensure outstanding system performance. This brochure provides a basic overview of some of the key selection factors that should be taken into account when choosing a linear motor. For detailed calculation and sizing information, please refer to the ETEL linear motors handbook, or ask an ETEL application and support engineer for assistance. IRONLESS LINEAR MOTOR Winding codes Under static conditions with an applied load, one motor phase can get...

Innovative Motion Control CASE STUDIES ETEL linear motors in CMM machines ETEL product range in flying probe tester machines Metrology machines are among the final steps of a manufacturing process which ensure that the final workpiece is under the proper specifications for mass production. Coordinate measuring machines (CMM) are used as part of this process by using a measuring probe moving through X-Y-Z planes to take points along a workpiece surface in order to properly measure any deviations for the desired specifications. As the tolerance standards for machine parts increase along with...

Innovative Motion Control ETEL’S LINEAR MOTORS IN HIGH-END MOTION PLATFORMS ETEL technology in wafer inspection motion systems ETEL specific motor design in short stroke actuators Linear motor technology is also a key performance enabler for semiconductor applications of advanced motion solutions. Today, serving current and future needs of advanced solid-state electronics manufacturers, means mastering positioning challenges at nanometer level. When the tolerable error budget is a small fraction of the gate length and dynamics need to sustain continuous throughput enhancement, ETEL motion...
