Help please i am formula illiterate

[native34]

Could someone please help me understand what this stuff means and how to use these formula's to figure out the proper stepper motor size for my application?


hen a stepper motor is selected, eight different things must be considered:
Operating speed in steps/second
Torque in oz-in.
Load inertia in Ib-in.2
Required step angle
Time to accelerate in ms
Time to decelerate in ms
Type of drive to be used
Size and weight considerations

Some of this information will be provided from application specifications, such as the size and weight considerations, step angle, and the operating speed. Other information must be calculated. Several formulas are provided to help you with these calculations.

Calculating Torque
The formula for calculating the torque is


Calculating Load
The formula for equivalent inertia to overcome friction in the system and enough torque to start or stop all inertia loads is


Frictional and Rotational Acceleration Considerations
The formula for calculating the torque required to rotationally accelerate an inertia load is
