More than a dozen large synchronous motors independently developed by **Tellhow Shenyang Electric Machine Co., Ltd.** (formerly Shenyang Electric Machine Factory / Shenyang Electric Machine Co., Ltd.) have been operating continuously and reliably for over seven years in a major Russian mining project. Their outstanding performance has earned high recognition from users, marking another key breakthrough for China’s high-end mining equipment power systems in overseas markets. The products applied in this batch include the TDMK3150-40 and TDMK2500-40 models, specifically designed to drive core mining industry equipment such as large ball mills, high-inertia ball mills, and semi-autogenous mills. They have successfully replaced and upgraded the user’s old motor systems, fully supporting the core production processes of the mine.

This series of motors demonstrates excellent performance under harsh mining conditions, featuring strong direct-on-line start capability and the ability to drive high-inertia mills smoothly. Over more than seven years of operation, the motors have maintained stable working conditions, with key parameters such as vibration, temperature rise, and current performing perfectly. Their high operational efficiency and good power factor have also brought significant energy-saving benefits to users.

Based on this positive experience, the user has continued to choose the same series of products from **Tellhow Shenyang Electric Machine Co., Ltd.** for equipment upgrades and expansion projects, establishing a stable partnership. This ongoing cooperation reflects the user’s full trust in the quality and technical service of Tellhow products.

**Tellhow Shenyang Electric Machine Co., Ltd.** inherits the technical heritage of the original Shenyang Electric Machine Factory in the field of large synchronous motors and continuously innovates and optimizes products to meet modern industrial demands. The successful application in Russian mines demonstrates the reliability and adaptability of the company’s products under heavy-duty conditions, while enhancing the reputation of Chinese high-end equipment in overseas markets.

From steel to mining, **Tellhow Shenyang Electric Machine Co., Ltd.** continues to deliver reliable Chinese power on the broad stage of the Belt and Road Initiative with its deep technical expertise and continuously innovative products. The company remains committed to providing global heavy industry clients with more efficient, durable, and intelligent large-scale motor systems, supporting the sustainable development of mining and infrastructure worldwide.
