Bosch frequency inverters
Variable frequency inverters for general automation, materials handling, pumps, fans, and conveyor belts.
Bosch Rexroth frequency inverters
Frequency inverters control the motor speed when starting and stopping and throughout the operating cycle by means of an adjustable frequency. BEGE supplies the intelligent, universal Bosch Rexroth EFC inverter series.
Selecting the appropriate VFD – 5 factors
What makes a frequency inverter suitable for a specific drive? It can be tempting to select a VFD based solely on motor power, but there are other, more important considerations. We’ve listed five relevant factors below:
1. Application
Some applications require a specific power curve. It is important to pick a VFD that can meet such requirements. A pump, for example, will start up slowly due to the resistance of the liquid.
2. Maximum current
Check the motor’s nameplate for the maximum Full Load Amperage (FLA) and then pick a VFD capable of supplying at least this amount of current.
3. Overloading
Some applications will briefly require more (starting) torque or are subject to cyclic overloading. In these cases it’s best to pick a VFD capable of handling the drive’s specific demands.
4. Height
In principle, all frequency inverters are air cooled, which means they are influenced by the atmospheric pressure and ambient temperature.
VFDs installed at heights over 1000 m may experience cooling issues. It is strongly recommended to pick an inverter that is powerful enough to compensate for the lack of cooling.
5. Temperature
Frequency inverters generate heat that, if not sufficiently dissipated, can cause equipment to shut down or worse, sustain damage.
If the environment exceeds the manufacturer’s specified maximum operating temperature, additional ventilation or cooling of the VFD is crucial.
