New approach for power modules

Power modules with five cooling concepts

Five cooling concepts for seven frame sizes allow you to select the optimal power modules for your requirements.

Baumüller has adopted a new approach with its power modules. To enhance diagnostics capability, the power modules are coupled with the drive controller via internal, serial communication. In this way, the drive controller can be parameterized independent of the size of the power module. The amount of engineering required is reduced. The power modules are provided with integrated line voltage measurement for operation in different networks throughout the world, e.g. the USA.

A wide variety of cooling concepts allow you to select the optimal cooling system. The push-through cooling concept greatly reduces power loss in the control cabinet. Depending on the application, cost-intensive cooling and air-conditioning systems are not required.

The utilization of the water cooling version paves the way for a reduction of the construction volume and, as a result, cost-effective control cabinet designs can be implemented. Stainless steel cooling systems guarantee low-maintenance operation and high availability.

Braking energy

Brake resistor activation is integrated in the form of a brake chopper. A regenerative resistor is connected externally. This paves the way for optimal dimensioning and also reduces the volume of the control cabinet.

Line filter

To optimize configuration from a cost perspective, line filters are always connected in series outside the device. Several power modules can thus be grouped for each line filter resulting in reduced costs for the system as a whole.

Temperature-dependent fan control

The fan is controlled relative to the temperature inside the device. This leads to a reduction in energy consumption and therefore lowers the overall costs of a system.

DC link coupling

DC link coupling can be achieved for a number of power modules for the purpose of energy compensation. Surplus energy is not “burned”. It is made available to other drive units without taking additional energy from the supply network.

Safety module

With the optional safety module, the option “safety stop” in accordance with EN954-1 safety category 4 can easily be realized without the integration of additional contactors in the motor line. This ensures that the structure of the safety circuit remains simple and transparent. The danger potential of the machine is reduced – the machine works reliably.
