SERIES DA

 


The servomotors in the DA Series are characterized by their extreme precision in control tasks and a minimal detent torque and are therefore ideally suited to measurement engineering where positioning accuracy in the μ range is a matter of course.

DA motors are optimized for etremly smooth running and the smallest gear ratio and are thus especially sought-after in the sensitive and efficient machines used in precision industries

Continuous line = Continuous operation
At an ambient temperature of 25° C, the maximum rotor temperature is attained in case of continuous load.
Dotted line = Repeatable range of operation (S-3)
This range can be used under different load characteristics. It is limited by temperature effect, commutation and demagnetisation.

 

Dotted two-point line = Short-time operation
The motor may be loaded for a short time and recurrently. If this range is exceeded, the motor is damaged irreversibly.


Remarks
Tolerances according to VDE 0530. A tolerance of +/-10% is applicable for values not specified according to VDE 0530.
In case of assembly of a shaft seal at the drive shaft, a slightly lower torque should be expected due to frictional losses.


The technical specifications given in the table and in the power curves refer to DC voltage supply with a permissible harmonic content of up to 5%.
The specifications are applicable only for the use at an ambient temperature of 0°C to 40°C. This range should neither be undershot nor exceeded, since there is otherwise the risk of permanent magnet weakening.
