Linear motors (LM) enable linear movements at high speeds with great accuracy. Most linear motors are used in the machine construction industry and for production automation purposes. In this White Paper, the following information can be found:- The basic physical principles of linear motors
- The 3 phase linear motor considered
- A comparison of standard electric (rotary) motors and linear motors
- The positioning system
- A brief description of a linear motor system and some practical considerations
- A brief description of both Tecnotion’s ironcore and ironless series of linear motors

Translating a superb theoretical design into a reliable servo requires attention to the mundane practical details that often eludes a gifted designer’s interest.
Poorly designed ground connections, for example, can lead to inadequate protection against common mode errors—or crosstalk in multi-axis motion control systems. Power supply selection that’s left to last moment decision may inhibit servomotor acceleration. Or the unusual duty cycles of a PCB drilling system—if not anticipated—cause MTBF-degrading heat dissipation. And don’t wait for a power supply explosion to focus attention on regenerative braking deficiencies.
This article may help differentiate between a superbly performing servo, and persistent problems that create customer friction or costly field fixes.

Energy is not a fixed cost, but rather a variable cost and there are many ways to improve energy efficiency such as turning off or dimming the lights when not needed, setting computers to hibernate when not in use, changing to more energy efficient light bulbs and introducing energy efficient strategies in automation.
Using energy in an efficient manner will cut running costs and benefit the environment and as a result, can significantly boost the image of a...Categories: Product Videos & Webinars - Posted: January 29, 2012
Linear motors have earned a reputation as highly precise and efficient alternatives to conventional rotary-to-linear transmission systems. Find out why, plus learn about the ultra-precise and energy-efficient linear shaft motor.
To fully appreciate the chief advantages of linear motors, it is helpful to compare them to ballscrews, another high-precision rotary-to-linear transmission system. Although typical ballscrews are roughly 90% efficient, servomotor efficiency (typically 75% to 80%) — plus losses introduced by the coupling and gearbox — reduces the power supply going toward actual work to 55% in some cases. In comparison, typical linear motors drive loads directly, which boosts overall efficiency.When the flat iron core motor (bottom) was introduced, it was more efficient than alternate forms of linear motion systems...Categories: Technical Support - Posted: January 29, 2012

There are a few different methods for developing a LabVIEW application that can communicate to a Galil motor controller.
1 – DMCWin32 Library and Galil developed VI’s. This method is simple, but limited support is offered beyond the vi’s that are provided on the Galil software CD.
2 – Active X Toolkit. This method has been the preferred method for any existing applications with LabVIEW and Galil motor controllers. It requires the purchase of the Active X Toolkit for $595 US. Details on using the Active X Toolkit with LabVIEW are covered in application note 4414. https://www.galilmc.com/support/appnotes/software/note4414.pdf
3 – GalilTools Communication Library. Using the GalilTools Communication Library is the recommended method for any new applications that are being developed with LabVIEW. This post will review 2 examples. The first covers basics of how to integrate the...Categories: Technical Support - Posted: August 02, 2011
The new Galil Sine drive amplifiers are a welcome addition to the existing DMC-40×0 and DMC-41×3 line-up of servo and stepper amplifiers – yet the addition of the new amplifiers also brings up a question – “When should I use a sinusoidal drive instead of a trapezoidal drive?”. This article will go over the Galil brushless servo drive architecture and highlight what you should know when making an amplifier selection.
Two Loop Architecture
In order to gain a better understanding of servo amplifiers and specifically how the Galil servo amplifiers work, the first thing to do is to understand the Controller/Amplifier architecture. Unlike most single axis drives on the market, Galil uses a split sample rate. The first and highest speed sample rate occurs on the amplifier and is used on the current loop. The D3540 Sinusoidal amplifier runs its current loop at 33 kHz and the D3040 Trapezoidal amplifier...
