MotionSizer is a free download and can be used to size servo or stepper motors and drives for industrial applications. It is fast and easy to use with an intuitive interface.
There are 3 basic steps in using MotionSizer: 1. Define Axis. 2. Define Velocity Profile. 3. Set SafetyFactors & Product filters.
If a user is trying to quickly find a Kit motor for an application, the desired torque is needed, speed and the voltage available on the machine.
1. Define Axis
Click Generic mechanism and Append. Input inertia as low value and if needing a specific torque,input the torque as the Friction Torque at Shaft.
The more accurate the input, the better accuracy of the motor sizing results.
2. Define Velocity Profile
Quick Setup allows users to input a speed over a set time and either trapezoidal or triangular motion profile and an optional dwell time.
If the customer has only specified a desired speed, input as a velocity and input some number as Total time. MotionSizer would presume this runs continuously.
If the actual application runs for a some time and then stops for a long time, input a long dwell. (This can have a very large effect on motor size results based on the RMS (root-mean-square) continuous torque calculation for the move profile.)
3. Set Motor Selection filters:
a. Voltage and Product filters:
Set the machine's voltage available, either with the AC or DC presets or User Defined AC/DC Power Source input.
Select Filter Motor List and set K series motor family.
Users can use default drives (newer Parker drives) or Generic Amplifiers.
If selecting Generic Amplifiers, you must click Active Products.
(By default, only Featured Products are selected (newer Parker drives) and no results will display if only Generic Amplifiers are set in the Motor List.)
c. Factor of Safety
Set a Max Torque Margin. Setting this to 3 will not show motors that have 3 times the required torque and can narrow the search faster.
(Safety Factors are stored within Motion Sizer and not the sizing file, so if you re-run MotionSizer without these set the same, results will be different.)
4. Click Auto Select. As this runs the status bar will increment.
At any time, if you click Cancel, you may view the motors found.
This can take quite some time as MotionSizer does a thermal calculation on each motor/drive combination and there are over 2000 different K series kit motors,
between the different frame sizes, stack lengths and each having 26 different windings (13 windings wired in either Wye or Delta).
5. View results on Motor Selection screen.
Select column title to sort by Product Key, Drive/Amp, Torque by drive size.
6. Click Performance Curves to see motor/drive performance compared to application requirements.
Note: Report Generator Show Report or Create Word Doc will not work for Windows Office 365. Do not click Show Report or MotionSizer will close. Print Report will work if printing to a pdf.
