Schematic workflow for project planning
The following flow diagram illustrates the project planning procedure for drive selection. The drive consists of a gearmotor that is supplied by an inverter.
Required information about the machine to be driven
- Technical data and ambient conditions
- Speed setting range
- Calculating the travel cycle

Calculation of relevant application data
- Travel diagram
- Rotational speeds
- Static, dynamic torques
- Regenerative power
|
↓ |
Gear unit selection
- Define the gear unit size, gear unit ratio, and gear unit design
- Check the gear unit load
- Check the input speed
|
↓ |
Motor selection
- Maximum torque
- With dynamic drives: effective torque at medium speed
- Maximum speed
- Observe dynamic and thermal torque curves
- Motor equipment (brake, plug connector, thermal motor protection, etc.)

Inverter selection
- Selection of communication
- Motor/inverter assignment
- Check whether the inverters fulfill the duration and overload requirements
|
↓ |
Select other system components
- Motor and supply system cables
- Signal cable
- EMC accessories
