Copperhill Media offers literature on servo motor sizing that is available as paperback through Amazon.com or in form of eBooks (PDF) through the publisher’s web site.
The Importance of servo motor sizing should not be underestimated. Proper motor sizing will not only result in significant cost savings by saving energy, reducing purchasing and operating costs, reducing downtime, etc.; it also helps the engineer to design better motion control systems. However, the knowledge of mechanical systems and their influence on motor speed, inertia and torque requirements seems to decline in a world where modern technology aspects, such as tuning and programming, seem to be the main focus. The motor sizing process involves a number of mathematical equations, which are most certainly documented, but not necessarily with the motor sizing process in mind. A Comprehensible Guide to Servo Motor Sizing by Wilfried Voss focuses primarily on servo motor sizing and it documents in detail the inertia and torque calculations of standard mechanical components and the motor selection process.
‘A Comprehensible Guide to Servo Motor Sizing’ describes all equations and algorithms necessary for the sizing process, including inertia and torque calculations for mechanisms such as lead screws, rotary tables, actuators, gears, and more. Also included is the calculation of duty cycles including a detailed description of S-Curve (Jerk Limitation) calculation.
The information in the book is accompanied by a free download of VisualSizer, the most popular servo motor sizing software in the motion control business. To download VisualSizer: http://www.visualsizer.com.

Why is Servo Motor Sizing so important?
The importance of servo motor sizing should not be underestimated.

Calculation of Motion Parameters
This page provides all equations necessary to determine the parameters of a triangular or trapezoidal motion profile. The equation address velocity, acceleration, distance and time based on what parameters are known and which need to be determined. Click here to read more…
Holding Brake and Motor Torque Requirements
The effect of a holding brake on motor torque requirements is usually minimal in a regular rotary or linear horizontal motion application and is therefore not necessarily recommended. However, the torque and power reduction can be quite dramatic in case of vertical linear applications. Click here to read more…
Servo Motor Selection Criteria
The motor data needed to select a motor are rated speed, rated torque, intermittent torque, and rotor inertia. However, the best servo motor selection criteria is to use the motor’s performance curve (torque over speed) and to verify it with the application requirements. Not all motor data sheets do provide such detailed information, since some manufacturers prefer to define the rated/intermittent torque and the rated speed of their motors in a more conservatively manner. Under certain conditions it is, however, possible to operate motors beyond their rated data. Click here to read more…
Optimizing motion-control-system design
Choosing the right PC-based motion-control system requires evaluating motion controllers, software, amplifiers, motors, and positioning hardware.

When to Choose a Linear Motor
For rotary or linear motors, motion is produced the same way and the same basic physics and electromagnetic forces apply. The theory that produces “torque” in a rotary motor produces “force” in a linear motor. But a closer look reveals that linear motors provide unique advantages for motion applications. Click here to find out how linear motors work and what the advantages are for motion applications.
