Robust drive technology for extreme industrial environments

AuCom will showcase the series from 25 to 27 November 2025, at SPS - Smart Production Solutions (Stand 326, Hall 3A). The 1 kV VFDs impress with high torque at low speeds and a durable, compact design.

"Extreme temperatures, high humidity, explosion hazards, or constant vibration - none of these pose a problem for the 1 kV frequency converters," said Thomas Zirk-Gunnemann, CEO of AuCom Applied Motor Controls. "Whether in mining, the steel industry, the energy sector, water management, marine applications, or the chemical, oil, and gas industries - companies in these fields benefit from the strengths of the HM Series."

Precise control, grid-friendly, and energy-efficient

Wherever performance and precision are needed in drive applications, the HM VFDs impress. The series covers a power range from 45 to 1250 kW (31–750 A, 1000–1300 V). The energy-efficient NPC three-level topology achieves a frequency conversion efficiency of up to 98 % while reducing harmonics. Available in 2- and 4-quadrant versions, the VFDs allow fast braking as well as regenerative feedback into the grid. The integrated Active Front End (AFE) ensures minimal grid disturbances.

The powerful vector control for synchronous and asynchronous motors - with or without encoder - enables precise control and high torque even at low rotational speeds, making it ideal for drives in conveyors, cranes, and winches.

The robust design of the HM Series, featuring laminated busbars and film capacitors, is also exceptionally compact, allowing installation in pressure-resistant and confined enclosures such as those used in mining. The CAN interface enables master-slave operation for multi-motor systems. In addition to the LED keypad, the optional touchscreen ensures easy parameter setup. Remote monitoring is possible via Ethernet or app.

The AuCom team warmly invites you to visit Stand 326 in Hall 3A at SPS and looks forward to inspiring discussions.
