Drive dimensioning
In order to carry out an accurate drive dimensioning process, you can use our conguring
soware, the »Drive Soluon Designer«.
With the «Drive Soluon Designer«, you can design the drive both quickly and to a high
quality. The soware contains profound and proven experse with regard to drive applicaons
and mechatronic drive components.
Please get in touch with your Lenze representave.
NOTICE
The dimensioning is suitable for the operang modes S1, S2, S3 and S6
The following 3 elements are taken into consideraon in the dimensioning process :
Drive funcon
On the basis of the values required for the process that are specied, a drive is selected, for
which all operang points are within the speed-torque characterisc curve of the motor.
As a result, a motor with a suitable speed with an inverter with a sucient maximum current
is selected. Further limits (maximum speed, installaon height...) are specied in tables.
Mechanical strength
On the basis of the forces and torques which build, a drive is selected that has a sucient
mechanic strength (endurance strength for the periodically occurring torques and faque
strength for the sporadically occurring torques).
Thermal dimensioning
For the inverter, the thermal dimensioning process is carried out on the basis of the
connuous inverter current or on the basis of the connuous torque from the motor-inverter
combinaon, which can be reached.
The motor is thermally dimensioned on the basis of the mean speed and the eecve torque.
The thermal dimensioning of the gearbox is based on the medium speed and the permanent
torque of the motor/gearbox combinaon. The thermal limit speed is to be understood as a
recommendaon.
The mean speed of the drive should not exceed the values specied.
