Technical description
Synchronous servomotor
18
Version: 2.1
OCT
This model features a different feedback system in place of the resolver.
Installation options and reduction of rated values
• With the exception of the sealing ring, the options cannot be retrofitted.
• The option sealing ring can lead to a reduction of the rated data.

Selection criteria
The three-phase servomotors are designed for operation with servo terminals.
Both units together form a speed or torque control Loop.
The main selection criteria are:
•
Standstill torque
M0 [Nm]
•
Maximal torque
Mmax [Nm]
•
Rated speed at rated supply voltage
nn [min-1]
•
Moment of inertia of motor and load
J [kgcm²]
•
Effective torque (calculated)
Mrms [Nm]
The static load
and
the dynamic load (acceleration/braking) must be taken into account in the calculation of
the required motors and servo terminals. Formulas and calculation example are available from our
applications department on request.
