Yaskawa Electric continuously improved machine performance in terms of speed and accuracy and performance according to customer demands on the basis of the company's technological expertise.

Because a linear motor is directly coupled to the load high positioning accuracies and wide operational speed ranges compared to other conventional drive/ translation mechanismsare achieved. An unlimited linear travel envelope can be obtained by coupling the stationary magnet tracks as needed.

Machine Performance

• Rare high energy magnets enable the linear motor high force density in compact units. Advanced magnetic circuitry, optimum winding geometry and d-q axis current control method enhance force linearity even near the peak force regions.

Simplified Machine Design & Construction

Since the moving part of the motor is rigid and is directly fixed to the load, the linear motion mechanism's stiffness is greatly improved. Multiple moving motor units can be operated independently over a single axis of the magnet track, a variety of motion can be generated from a very compact drive system. High dynamic stiffness of Linear Sigma motors combined with a Sigma Servo-drivers system reduces settling time after motion and improves machine motion cycle specifications.

Silent Operation & High Reliability

Linear motors are quiet even at high speeds since the only contacting mechanisms in the linear motor system are the linear motion slides. The system reliability is increased and maintenance requirements are reduced.

Application:

• The closed loop-linear servo system enhances smooth linear motion with minimum velocity ripple.
• The Linear Sigma Servomotor reachs a speed of up to 9 meters per second whereas operational speed ranges are not limited by factors such as travel length of the system.
• he Linear Sigma motors reach 20G of maximum acceleration.
• Optimized magnetic circuitry design and high-density windings from Sigma Servomotors result in remarkable energy efficiency of the Linear Sigma Direct Drive Servomotors
