3.3.1 1. Clarification of the type of drive
The motor is selected on the basis of the required torque, which is defined by the application,
e.g. traveling drive, hoisting drive, feed drive or main spindle drive. Gear units to convert
motion or to adapt the motor speed and motor torque to the load conditions must also be
considered.
As well as the load torque, which is determined by the application, the following mechanical
data are among those required to calculate the torque to be provided by the motor:
• Masses to be moved
• Diameter of the drive wheel/diameter
• Leadscrew pitch, gear ratios
• Frictional resistance
• Mechanical efficiency
• Traversing paths
• Maximum velocity
• Maximum acceleration and maximum deceleration
• Cycle time
3.3.2 2. Definition of supplementary conditions and integration into an automation
system
You must decide whether synchronous or induction motors are to be used.
Synchronous motors are the best choice if it is important to have low envelope dimensions,
low rotor moment of inertia and therefore maximum dynamic response.
Induction motors can be used to increase maximum speeds in the field weakening range.
Induction motors for higher power ratings are also available.
You should also specify whether the drives are to be operated as single-axis drives or in a
group as multi-axis drives.
The following factors are especially important when engineering a drive application:
• The type of line supply, when using specific types of motor and/or line filters on IT line
supply systems (non-grounded systems)
• The utilization of the motor in accordance with rated values for winding temperatures of
60 K or 100 K
• The ambient temperatures and the installation altitude of the motors and drive
components.
Other boundary conditions apply when integrating the drives into an automation environment
such as SIMATIC or SIMOTION.
