Recommended areas for
continuous operation
Note:
The diagram indicates the maximum
speed in relation to the available torque
at the output shaft for a given ambient
temperature of 22°C.
The motor can provide more power with
adequate cooling (for ex. R
th 2
reduction
of –55%).
The maximum available torque and speed
will be reduced if the ambient temperature
is higher than 22°C and / or the motor
is thermally insulated to the ambient
environment.
