1. Clarification of the drive type
Select the motor on the basis of the required torque (load torque), which is defined by the
application, e.g. traveling drives, hoisting drives, test stands, centrifuges, paper and rolling
mill drives, feed drives or main spindle drives.
Gearboxes to convert motion or to adapt the motor speed and motor torque to the load
conditions must also be taken into account when selecting the motor.
You must know the following mechanical data in order to determine the torque to be supplied
by the motor:
● The load torque specified by the application
● Masses to be moved
● Diameter of the drive wheel
● Leadscrew pitch, gear ratios
● Frictional resistance data
● Mechanical efficiency
● Traversing distances
● Maximum velocity
● Maximum acceleration and maximum deceleration
● Cycle time

2. Specification of the supplementary conditions and integration into the
automation system
Take the following into account during the confguration:
● The line system configuration when using specific motor types and/or line filters
● The utilization of the motor rated values for winding overtemperatures of 60 K or 100 K
(for synchronous motors)
● The ambient temperatures and the installation altitude of the motors and drive
components
● The heat dissipation from the motors through natural ventilation, forced ventilation or
water cooling
Other conditions apply when integrating the drives into an automation environment such as
SINUMERIK or SIMOTION.
For motion control and technology functions (e.g. positioning), as well as for synchronous
operation functions, the corresponding automation system, e.g. SIMATIC S7-1500 or
SIMOTION D is used.
