SERVOMOTORS
(DA Series)
The servomotors of the DA series are characterized by their extreme accuracy in control with a minimal residual torque, and are therefore predestined for use in metrology where accuracy of positioning in µ-area is expected. The perfect concentricity and the small installation dimensions will make them especially suitable for sensitive and efficient machines needed for economic production.
SPECIFICATION
TECHNICAL DATA
SPEED AND TORQUE
Solid line = continuous operation: At an ambient temperature of 25 ° C, the maximum armature temperature is reached with continuous load.
Dashed line = repeatable work area (S-3): This area can be used under different load characteristics. It is limited by the influence of temperature, commutation and demagnetization.
Dashed two-dot line = short-term operation: The motor may be loaded briefly and repeatedly. If this range is exceeded, the motor will be irreversibly damaged.
Remarks
Tolerances according to VDE 0530. For values not specified according to VDE 0530, a tolerance of +/- 10% applies.
If the output shaft is fitted with a shaft seal, a slightly lower torque is to be expected due to friction losses. The technical data given in the table and the performance curves relate to a DC voltage supply with a permissible harmonic content of up to 5%. The data are only valid for use in an ambient temperature of 0 ° C to 40 ° C. This range must neither be exceeded nor fallen below, otherwise there is a risk of permanent magnetic weakening.

EQUIPMENT
Attachments for engines
Gearbox: Planetary gearboxes of the PLE series are available for all motors. An assignment and a detailed description of the gearbox to the individual motor types here.
Brakes: The brakes are spring-applied holding brakes, which are described in more detail in the Braking section.
Encoder: The associated encoders are magnetic shaft encoders with a pulse count of 500 (motor 4DA) or 1000 pulses / rev (motor 5DA – 8DA).
Tachos: DC tacho generators with a voltage constant of 3V (motor 4DA) or 5V / 1000min-1 (motor 5DA – 8DA) are used as tachos.
DC servo controller: An assignment of the controller to the motor types and a description of the controller can be found in the section Servo controller.
