Kolmer Electric Motors

What Kolmer Electric Motors does

Kolmer Elektromotoren B.V. is a privately held Dutch specialist distributor and service provider of industrial electric motors, operating from a modern ISO 9001-certified facility in Harderwijk since its founding in 1984. The company holds a physical inventory of approximately 20,000 motors spanning IEC frame sizes 56 to 355 and power ratings from 0.04 kW to 7,000 kW, sourced primarily through long-standing exclusive partnerships with European manufacturers Cantoni Motor (Poland, IE3/IE4 high-efficiency motors) and Cemp (Italy, ATEX pressure-resistant explosion-proof motors). Kolmer serves industrial machine builders, maritime, ventilation, compressor, and ATEX-regulated chemical/feed/food/waste customers across the Netherlands and broader Europe, with a direct sales engineering team plus a national certified service partner network.

Kolmer's product portfolio is anchored on third-party branded motors enhanced with proprietary value-added services. The Kolmer Top Coating is an in-house surface treatment that anchors into aluminum and cast iron substrates to prevent flaking and rust, extending motor lifespan by a factor of four in harsh environments. A dedicated subsidiary, Kolmer Special Motors B.V., operates an in-house engineering team and a state-of-the-art spray booth workshop for custom motor configurations, including a 24-hour custom brake motor delivery program that includes specifications, drawings, and STEP files. The company is also an authorized Cemp ATEX repair shop and claims the largest ATEX motor stock in the Netherlands.

Revenue is generated through three streams: (1) hardware sales of standard and custom-configured motors via direct sales engineers and account managers, (2) custom engineering and modification services including Kolmer Top Coating, and (3) aftermarket services including 24/7 motor replacement and root cause analysis. Pricing is quote-based with multi-year contract cadence, and go-to-market relies on a combination of direct enterprise sales, an online Cantoni motor configurator, annual Partner Day events, and trade publication coverage. The company is privately owned with no disclosed institutional investors, external funding rounds, or M&A activity.
