A variable speed drive should be selected from the motor and application data. Motor kW is a useful starting point, but rated current, supply voltage and load duty are equally important.
Information to collect before selecting a VFD
Record the motor nameplate before choosing the drive. This reduces the risk of selecting a drive that matches the nominal kW but not the actual current or supply.
- Motor kW
- Motor rated current
- Supply voltage and phase
- Application type
- Required speed range
- Ambient and enclosure conditions
Altivar for different applications
Schneider Electric Altivar ranges cover different machine, process and building applications. For example, HVAC and pump duties may have different requirements from conveyors or higher-torque machinery.
Installation considerations
Drive selection should also consider enclosure, ventilation, cable length, EMC requirements, control method and any communication requirements. Final engineering should follow the project specification and manufacturer documentation.

Frequently asked questions
Can I choose a VFD only from motor kW?
Motor kW alone is not sufficient in every application. Check motor current, supply and duty.
