DC servo motor basics
I am an Electronic Engineer and need some Mechanical help for understand Servo motor:
Plz help me understanding Servo motor basic;
What is Motor inertia?
What is Rated Torque?
What is Stall Torque?
what is maximum Peak torque?
What is relationship between Torque and RPM and Watt?
Regards,
Ishaq

The reason to ask this question was to understand the servo terminologies.
I have searched for 100-200 oz-in BLDC servo motor and found that a 6VDC servo motor produces the same torque as a 48VDC servo motor.
How can I differentiate in these motors so I can reach a suitable solution.
e.g
6VDC Servo motor:
BLS253 Brush-less 3D Heli Servo
Futaba® Brushless Servos | 90D
48VDC Servo Motor:
60BLS Brush-less Servo Motor:
Brushless DC Servo Motor, Brushless Servomotor, 3 Phase Servo Motor, Servo Motor
In simple terms, motor inertia is the same for inertia in general, it is the effort required to move from one state to the next, in the case of a motor, a lower inertia motor will accelerate faster then a higher inertia motor for a given current.Originally Posted by ishaqahmed
Current which equals torque, and the stall torque or sometimes called continuous torque is the equivalent current that can be applied continuously without damaging the motor.
Maximum peak torque is the maximum current that can be applied before damage to the motor results.
The industry standard for motor to load inertia ratio is to attempt to keep this under 10:1, apart from motor load, required accel and decel rates affect this figure.
Reduction will increase torque by the ratio of the reduction, and the motor to load inertia ratio will be reduced by the square of the reduction.
