SISME Group

What SISME Group does

SISME Group (legal entity: Sisme S.p.A.) is a privately held Italian manufacturer that has designed, developed, and produced electric motors since 1957, when it was founded in Olgiate Comasco (Como) by US multinational Ranco. The company specializes in asynchronous, brushless permanent magnet (PMM), LSPM (Line Start Permanent Magnet), and IPM (Internal Permanent Magnet) synchronous motors, including rotors and stators for hermetic and semi-hermetic refrigeration compressors, air and water movement motors for HVAC and appliances, and traction motors for electric mobility applications (motorcycles, scooters, kick scooters, e-bikes, automotive auxiliaries). Technology is supported by an integrated R&D process that spans customer requirements analysis, electrical and mechanical sizing, prototyping, testing, and industrialization, with in-house dynamometer, hydraulic, and aeraulic validation capabilities and ISO 9001:2015 certification.

SISME operates three wholly-owned production facilities — the headquarters and primary plant in Olgiate Comasco (Italy, ≈300 staff and R&D, sales, quality, IT and purchasing functions), a plant in Veľký Krtíš (Slovakia, ≈200 staff) serving European compressor customers, and a plant in Tianjin (China, ≈200 staff) serving Chinese and Southeast Asian compressor markets. The company has produced over 100 million motors cumulatively and currently outputs 15,000+ motors per day, with roughly 80% of output exported to Europe, the Americas, Australia, Africa, and Asia.

The business model is an OEM/tier supplier model: SISME co-designs custom motors with multinational manufacturers and embeds them as components in compressors, HVAC equipment, and home appliances, with revenue generated via direct enterprise sales, long-term supply agreements, and bundled R&D/engineering services. Named enterprise customers include Bosch & Siemens (BSH), Danfoss, Trane, Bock Compressors, Frascold, Copeland, Carrier, Electrolux, and La Marzocco; BSH has been a consecutive Best Motor Supplier award recipient since 2001. There is no retail or channel-partner distribution: pricing is private and quoted per specification, volume, and contract.
