5 Steps to Choose Servo Motor, Say Goodbye to the Worries of Choosing the Wrong Model
Have you ever experienced equipment shaking or substandard accuracy due to improper selection of servo motors? Are you dizzy from being surrounded by various parameters during torque calculation? This article will break down the entire selection process through practical cases, and at the end of the article, a "Quick Reference Manual for Servo Motor Selection" will be prepared to help you quickly master this compulsory course.
In the fields of industrial automation, new energy vehicles, and intelligent manufacturing, the load matching problem of motor controllers is becoming a key factor affecting equipment performance and energy efficiency. Industry data shows that the failure rate of motor controllers caused by improper load matching is as high as 22%, and the average annual unplanned downtime loss of enterprises exceeds one million yuan.
A certain electric vehicle manufacturer once experienced frequent power system failures due to a mismatch between the motor controller and the load, resulting in a single repair cost of up to 150000 yuan. So, what is the reason for the difficulty in load matching of the motor controller? What precise solutions are hidden behind this to adapt to different loads?

5 core parameters that must be mastered
Torque Calculation: Conversion Techniques from F=ma to Actual Operating Conditions
The correct usage of formula T=9550 * P/n
Three calculation methods for acceleration and deceleration torque (with calculation template attached)
Hidden traps for speed matching
Principle of choosing between rated speed and maximum speed
The Golden Rule for Choosing Reduction Ratio
Practical points of inertia matching
4-step calculation method for load inertia conversion
Is the inertia ratio controlled at 3:1 or 5:1? (Comparison Table of Different Scenarios)
Parameterized expression of precision requirements
The Relationship between Encoder Resolution and Repetitive Localization Accuracy
Quantitative evaluation of rigidity and backlash

Selection and Avoidance Guide
Misconception 1: Only focus on power and not torque curve
Misconception 2: Neglecting the treatment of renewable energy
Misconception 3: Blindly pursuing imported brands
Misconception 4: The safety factor value is too high
