Frequency converters, modular design

kompakt

Frequency converters in modular design of the type series UNIDRIVE SP – 45 kW to 1.9 MW for regulation of AC motors (asynchronous / synchronous) 200 / 400 /575 / 690 Volt - AC- and servo drive with high performance – network re-feeding operation

Descriptiong

Unidrive SPM converters in modular design have the same functions and operating structures as Unidrive SP compact units; in addition, they offer a high degree of flexibility in performance and system configuration. As supply and converter modules are separate, they can be combined according to the requested performance. The converter modules can be connected to a shared DC current link for direct energy exchange between converters working on motor and generator side, without or with active supply for re-feeding of the brake energy into the network. With corresponding parallel switching of the converter modules, converter systems with high capacities can be realized.

Applications

Unidrive SPM supply and converter modules are suitable for commercial and industrial applications that require high system flexibility, e.g. in network supply and energy-saving solutions provide economic advantage.

Typical applications include:

  • Energy saving for high-performance fans and pumps
  • Metal generation and processing
  • Industrial crane test benches in the automotive industry for vehicles, motors and gear units, track control and winder drives
  • Transport and processing of bulk goods
  • Paper and cellulose processing
  • Ship building
  • Regenerative energy systems, e.g. solar systems

Overview of customer benefit

Unidrive SPM supply and converter modules have the same properties as Unidrive SP converters for wall mounting and offer the following additional system flexibility:

  • With corresponding parallel switching of the converter modules, converter systems with high capacities can be realized.
  • The solutions are extremely compact and economical. Installation is simplified and provides a high operational safety. For instance, cabinet heights of up to 1m are possible.
  • Reduction of operational costs due to shared use of the current link for energy exchange between braking and motor operation, e.g. for winders and unwinders.
  • Minimizing of the measured actual harmonics due to 12, 18 and 24 pulse rectifier configurations with strict network requirements.
  • Switching off of the measured actual harmonics with active network supply or net re-feeding.
  • Higher system redundancy due to modular system configuration.
