Inputs
User-classified record label only; the same shaft-power relation is applied and no motor class is selected or compared.
User-entered steady mechanical shaft torque at the stated operating point.
User-entered steady rotational speed at the stated operating point.
User-entered record-specific comparison reference; it is not validated against a motor curve.
User-entered record-specific comparison reference; it is not validated against a motor rating.

Method
Formula, when it applies, and when it does not
Calculate a shaft-power operating point and torque/power reference ratios for a user-classified servo, stepper, or AC motor record without assessing motor capability.
Pshaft = T·ω = T·n·2π/60; rT = T/Tref; rP = Pshaft/Pref
When
- User-declared motor class
- Declared steady shaft torque and speed
- User-entered reference torque and power
- Mechanical shaft-power relation
Don’t
- This applies the mechanical shaft-power relation to a user-classified servo, stepper, or AC motor record, then reports literal ratios to user-entered references. It does not compare motor types; select a motor/drive; predict torque-speed, holding, pull-out, overload, voltage/current, control, thermal, duty, efficiency, safety, suitability, or approval.
