But servo motor calculations are often based on inertia and seem far more complicated. This is because industrial motors tend to run at constant speed, with acceleration and deceleration being virtually ignorable parts of the duty cycle.

But in servo systems acceleration and deceleration form a much larger part of the cycle, they must be under perfect control and are often extreme in order to effect a significant speed change in a tiny time frame. Servo selection can seem even harder because the duty cycle may be complicated, involving say four or five separate accelerations, as many decelerations, several different fixed speed periods and variable loads and timings. However, the calculation procedure is simply to break the motion profile down to its component steps and work through each one in turn.
The thing to remember here is that the servo motor chosen has to be adequate for the biggest step in the cycle.smegsipalypurb.tk/map22.php

Most manufacturers now have on-line calculators. To use a calculator you just follow the instructions and insert the parameters of your application; it does the calculations and recommends suitable motor sizes and types. Machine design trends Trends in machine design include reducing component including motor size and increasing power requirements.
Servo motor makers are responding to both of these, but it is worth noting that more powerful motors often need higher supply voltages, so multi motor systems may need multiple power supplies. Some manufacturers offer power supplies that can provide two or more voltages. High performance motors can prove unreliable, usually because the higher voltage increases heat output which degrades the critical insulation.
The better motors will tend to have high quality insulation and potted stators for good heat dissipation. It is also worth checking a motor's seals, as servo environments can be quite demanding.
Servo motors are always used with servo amplifiers. They are always supplied as a matched pair, so by specifying the motor, selection of the amp becomes a resolved issue. It is a common design solution to ask a manufacturer to customise a standard motor with a bespoke shaft or bearings.
Motor mounting issues do not represent the exciting end of servo design, but the fact that there are mounting standards suggests that it is a very important matter. Servo motors may accelerate at incredible speeds, so must be securely mounted. They also need isolation to reduce vibration, noise and associated damage. Then there are safety standards and myriad national standards. You may also need to accommodate a bearing, gearbox, brake or other component.
