| The motor rotor inertia values are listed in the motor section
of the catalog. Please note there are two values listed for each motor size, with and without brakes. |
| The heavy flywheel is a cast iron high inertia fan available as an option with the NORD motors. It is used to soften the shock at start and stop. If you have no heavy flywheel set this value to 0. |
| Load moment of inertia reflected to the motor shaft. To calculate this value pick: "Linear moving body inertia reflected to input" or "Reflected inertia from output to input" |
| The motor speed under full load conditions ( Full-load means listed nominal power ) For values see the motor section of the catalog. |
| The maximum available brake torque for a selected motor is listed in the motor section of the catalog. |
| Load torque at the motor shaft or gearbox input shaft. |
| The overall efficiency consists of the driving unit ( the gearbox )
and the driven unit efficiency ( such as the chain or belt stage efficiency etc. ) see "Overall efficiency" calculation. |
