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
• Maximal torque
• Rated speed at rated supply voltage
• Moment of inertia of motor and load
• Effective torque (calculated)
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.
