 Why adopt linear motors?
 REDUCED COST OF OWNERSHIP
Direct coupling of the payload to the motor’s moving part eliminates the need for mechanical transmission elements such as leadscrews, timing belts, rack and pinion and worm gear drives. Unlike brushed motors, there is no contact by the moving parts in a direct drive system. Therefore there is no mechanical wear resulting in excellent reliability and long lifetimes. Fewer mechanical parts minimize maintenance and reduce the system cost. The direct drive technology intrinsic to a linear motor based system results in an efficient and effective gearless assembly.
EASY INTEGRATION
ETEL linear motors are available in a wide range of sizes and can be easily adapted to most applications. ETEL's unmatched standard product offering includes ironless and ironcore linear motors.
DYNAMIC PERFORMANCE
Linear motor applications have a wide range of dynamic performance requirements. Depending on the specifics of a system's duty cycle, the peak force and maximum speed will drive the selection of a motor.
WIDE FORCE-SPEED RANGE
Direct drive linear motors deliver high force over a wide range of speeds, from a stalled or low speed condition to high velocities. Linear motors can achieve very high velocities (up to 10 m/s) with a trade off in force for ironcore motors, as technology becomes limited by eddy current losses in magnetic field. |
