Robust and reliable motors from Groschopp: For greater safety in energy distribution

In energy distribution, drives in high- and medium-voltage switchgear are indispensable. They must function reliably even after long periods of standstill or sudden overloads to prevent damage and power outages. Groschopp AG provides tailor-made electric motors for this purpose.

"Safety and reliability play the crucial role in energy distribution," explains Christian Skaletz, Product Manager at Groschopp. Switchgear construction requires powerful, compact drives that safely buffer events such as short circuits, earth faults, or overloads with 100% certainty. They are also essential for personnel protection during maintenance work by enabling safe network shutdowns.

The commutator motors of Groschopp's KE series were designed specifically for medium- and high-voltage switchgear. These brushed DC motors stand out due to their durability and robust, repair-friendly design. In switchgear technology, they are mostly used as series-wound motors: they can be massively overloaded for short periods, run on both direct and alternating current, and deliver high starting torques – completely without external power electronics. Furthermore, they can be flexibly adapted to customer requirements. Current trends in switchgear construction
"The trend is currently moving towards PMDC motors," says Skaletz. These permanent-magnet motors are more compact than separately excited versions and offer excellent controllability, though they can reach their limits under high overloads. Another future-oriented topic is brushless direct current (BLDC) motors, which are increasingly convincing due to their maintenance-free operation and high performance.
Groschopp supports switchgear manufacturers with comprehensive consulting and custom-fit solutions. Quality and durability are the main focus to prevent expensive failures and ensure the operational safety of the entire infrastructure.
