PROGRAM
he LUDRIVE drive calculation program meets the wishes of many
users for quick and easy calculation of the various drive solutions.
The drive program is divided into two sections.
The first section contains a formula bank with 38 formulae for calculation
of:
• Moments of inertia of various bodies
• Moments of inertia of applications
• v/t diagrams
• Tractive resistances and friction moments
• Effective torque loads
• Various drive capacities
• Drive torques
With the aid of the second section complete drive units can be configured.
The drive data are entered in a practice-oriented sequence. This second
section supports the design of:
• Horizontal traction drives
• Traction drives with rise for upward movement
• Traction drives with rise for downward movement
• Lifting drives without counterweight (lifting)
• Lifting drives without counterweight (lowering)
• Indexing tables with ball rim
• Indexing tables with shaft through the center point
• Spindle drives
• Rotational drives
After calculating the drive L
UDRIVE displays a graph on the PC. The graph
shows the characteristic of the mean torque, the speed and the moment
over time. Based on this graph, the behavior of the drive solutions in prac-
tical applications can be assessed. Of course, all influencing factors
such as the rotor moment of inertia of the motor, the field weakening
range, the nominal winding point of the motor etc. are analyzed and/or
calculated and translated onto the graph.
In addition to the functions described, the L
UDRIVE program also sup-
ports ancillary functions such as Help, Print, Save and Load.
Note: The LUDRIVE drive program is based on the theoretical prin-
ciples of the book entitled “Das 1x1 der Antriebsauslegung”
(“The ABC of drive design”) - see "Bibliography and source
reference".
