How to Mate Yaskawa Motors with a Lintech Actuator

Greg Haley | November 21st, 2017

Yaskawa is a key manufacturer in the motion control world and has an impressive lineup of servo motors. All applications call for these motors to be connected to some sort of mechanical system to achieve the desired motion and functionality. One of the most common types of mechanics is a linear actuator, which Yaskawa does not manufacture or sell.

When an application calls for a linear actuator and it’s desired to take advantage of Yaskawa’s servo platform, it becomes necessary to find a manufacturer of actuators that is reliable but will also allow easy mounting of Yaskawa motors. LinTech is one such company that makes excellent mechanics and this tutorial will show what to look for when coupling these actuators with Yaskawa servos.

Step 1: Size the Actuator

LinTech’s actuator manuals have instructions and tutorials for how to size linear slides and actuators. The key thing to keep in mind here is you’ll want to select an actuator that comes with a motor mount compatible with Yaskawa. See the table below for which series has a Yaskawa motor mount option.

Table 1. Lintech series and Yaskawa motor compatibility.

Step 2: Select the Motor

There are several tutorials online and in the Yaskawa servo motor manuals, which describe how to size servo motors. An important item to be aware of is even though an actuator may support a Yaskawa motor, it might not support every size of Yaskawa Sigma 5 and Sigma 7 series motor. When configuring the actuator on LinTech’s websiteuse the motor mountoption drop-down list to see what Yaskawa motors are compatible with that particular series.

Step 3: Select the Proper Motor/Shaft Coupling

Now that the actuator and the motor have been selected (and the motor will mount to the actuator) the last thing to do is to select the proper coupling. Yaskawa servo motors typically have larger shafts than other manufacturers, so in most cases, the coupling option will need to be changed. Follow these steps to select a coupling:

Image 2. Three types of coupling offered by LinTech.
  • LinTech’s manuals describe the 3 different coupling options: C, H, and G. Select the one that best fits the application.
  • Find the shaft diameter of the motor in the Yaskawa datasheet.
  • Find the input shaft diameter of the selected actuator in the LinTech datasheet.
  • Check the maximum coupling diameter for the actuator series in the LinTech datasheet.
  • Select the proper coupling following this convention G126-312-014 where:
    • G indicates the coupling type.
    • 126 indicates the diameter of the coupling in inches.
    • 312 indicates the bore diameter of the coupling on the actuator side.
    • 014 indicates the bore diameter of the coupling on the motor side.*

Example: Using an SGMJV 200 W servo with LinTech 130 series actuator.

  • From the Lintech datasheet, the input shaft diameter is 0.312 inches.
  • From the Lintech datasheet, the maximum shaft diameter is 1.5 inches.
  • From the Yaskawa motor data sheet, the output shaft diameter of the motor is 14mm.
  • The application calls for a G type coupling.

Therefore, we need a G126-312-014 coupling.

*The value here can be either inches or mm, check LinTech datasheet for each series to see valid values.

Get the Most From Your Paired Devices

These are the steps to pair a Yaskawa servo motor with a LinTech actuator or slide. The two key items here are selecting actuators that have a standard mount option for Yaskawaand making sure the coupling will fit on the larger Yaskawa shaft. If you want to use Yaskawa with a LinTech actuator or slide that does not have Yaskawa as a standard option, contact us and we’ll be glad to help you solve your problem.

How to Upgrade from Yaskawa Sigma-II to Sigma-7

Greg Haley | September 6th, 2018 It doesn’t matter what industry you are in, at some point in time a product you’ve used for years will go obsolete and you will have to upgrade. Fortunately for Yaskawa servo users, this path to upgrade can be straightforward and easier than expected. This is thanks to Yaskawa consciously designing
