(1) Ambient temperature: 20°C Winding temperature rise: 120°C

Motor in natural convection mounted on a g150 flange

(2) Cold motor at 20°C

(3) Overload characteristics on a 540VDC bus Peak torque is available up to:

- 300rpm for 500rpm version

- 1 000rpm for 1 500rpm version

At nominal speed, peak torque is limited to the value of continuous torque at stall.

Load graphs are accurate if:

• Loads are gradual with no shock loading

• The motor is operating within its designed operating envelope

• Loads are applied to the midpoint of the shaft (no incurring large moments loads)

For irregular operating conditions (e. g. shocks, vibratios, cyclic loading, temperature, enviroment) please contact us.
