Lot of 5 Siemens SINAMICS Perfect Harmony GH180 Power Cells (Innomotics Serviced 2025)

Item Overview

This listing is for a lot of five (5) Siemens SINAMICS Perfect Harmony GH180 power cells. These modular power cells are the critical building blocks used inside Siemens medium-voltage variable frequency drives (VFDs). In a Perfect Harmony drive, multiple low-voltage cells are linked together in series to build the medium-voltage output — typically ranging from 2.3 kV to 13.8 kV at the drive terminals.

All five cells in this lot were recently sent to Innomotics Inc. (the dedicated motors and large drives company spun off from Siemens, headquartered in Nisku, AB) for full servicing. The service tags confirm that all five units underwent a Power Cell Service and Capacitor Replacement in April and May 2025. Because the electrolytic capacitors are the primary wear component in these cells, this recent factory service makes these units highly valuable as ready-to-deploy spares — no capacitor reforming procedure is required before installation.

Lot Inventory — All 5 Cells

The lot contains three distinct part numbers across two voltage ratings. All cells are designed for 50/60 Hz input.

Application

The SINAMICS Perfect Harmony GH180 is one of the most widely installed medium-voltage drives in the world, heavily utilized in the oil and gas, mining, and power generation sectors for controlling large pumps, fans, and compressors. Syncrude's oil sands operations rely extensively on GH180 drives for critical process equipment. The modular cell design allows a drive to bypass a failed cell and continue operating at reduced capacity until the next maintenance window, making on-shelf spare cells essential for minimizing downtime.
