1. Motor winding at temp. rise, δT = 100°C , at 40°C ambient
2. All data referenced to sinusoidal commutation
3. Add parking brake if applicable for total inertia
4. Motor with resolver feedback and standard heat sink
5. May be limited at some values of Vbus
6. Measured at 25°C
7. See de-rate chart for the de-rate of different motor options.
8. Brake motor adds 4.5 kg [10lbs]
9. Shaft seal increases Static Friction by 0.12 Nm [1.06 lb-in]
