Control quality
The control quality of a direct drive with torque motor is governed by the:
• Rigidity of the drive system (dynamic quality of the machine construction, bearing,
encoder mounting)
• The precision when mounting and adjusting the encoder system
• Quantification of the angular signal and speed signal (the number of encoder lines and
their multiplication in the encoder evaluation of the converter for each axes rotation and
the measuring accuracy of the encoder are crucial here).
• Sampling time of the current, speed, and position controller.
In addition to selecting a suitable motor, encoder and controller, the precision and control
quality of the machine axis is essentially determined by the integration into the overall
mechanical system. As a consequence, a general recommendation for integrating the motor
cannot be given for all axis concepts.
To ensure that the motor and the encoder are optimally integrated into the mechanical
structure, Siemens offers its Application & Mechatronic Support Direct Motors service, see
Catalog. For additional information, please contact your Siemens contact person, also refer
to the Internet link in the Introduction under "Technical Support".

Benefits

Features of the motors:
• Extremely high power density
• High torque with a compact design and low unit volume
• High overload capability (factor 1.7)
• The motors are adapted to the Motor Modules of the SINAMICS S120 drive system.
• High degree of availability as there are no gearbox components in the mechanical drive
transmission line which are subject to wear
• Water cooling to increase the rated power
• Directly flanged to the machine
• Axial cable outlet
As a result of water cooling, the motors meet high requirements regarding their thermal
behavior within the machine construction.
