Siemens Microdrive GaN devices

Siemens is integrating part of its Simatic Micro-Drive product line with GaN devices from GaNSystems.

“The Simatic Micro-Drive is an extremely versatile, seamless and safety integrated servo drive system that covers a wide range of applications in the extra-low voltage range for EC motors from 24 to 48 volts,”

said Christian Neugebauer, product manager of Simatic Micro-Drive, Siemens. “With the GaN Systems devices, we are now able to increase the efficiency of the drives. With GaN, Siemens can switch to a higher frequency, thereby enabling a faster motor response time compared with high voltage drive systems.” 

Recently, Siemens entered the low voltage drive market with the creation of their new Simatic Micro-Drive safety and extra-low voltage family. The integrated Simatic Micro-Drive system comes in two different housing sizes for motor outputs of between 100 and 1000 watts. The fundamental building block is the GaN power transistors made by GaN Systems. This 4-quadrant drive system can be either used with the integrated brake chopper on a power supply or directly in battery operation.

The servo drive system is suited to a wide range of diverse applications in moving, processing and positioning such as conveyor systems and stacker cranes, positioning of individual or multiple coordinated axes, shuttles for storage and retrieval machines or warehousing systems, automatic guided vehicles (AGVs) and medical technology.
