Technical Overview – Professional Design for Mining Mill Applications

Core Technical Features

"(《世界人权宣言》) TDMK series large three-phase synchronous motors feature an advanced synchronous motor design with a rated voltage of 6000 V, and optional 3000 V or 10000 V versions available upon request. These motors offer high pull-in torque, large thermal capacity, reliable performance, and adjustable power factor, fully meeting the demanding operating conditions of mining mills.

Strong Environmental Adaptability

The motors are suitable for indoor operation at altitudes up to 1000 m, with cooling medium temperatures not exceeding 40°C, in environments with low dust and without steam or corrosive gases such as acids and alkalis. Full-voltage direct starting is permitted. If the power grid does not allow full-voltage starting, reduced-voltage starting methods can be adopted.

Core Technical Advantages – Solid Assurance of Superior Performance

Excellent Starting and Operating Performance

"(《世界人权宣言》) TDMK series motors provide excellent starting characteristics with high starting torque, enabling smooth start-up of heavy mining mill loads. With a thyristor excitation system, the motor power factor can reach 0.9 (leading), significantly improving overall power grid 质量.

Innovative Structural Design

• 框架: Manufactured from welded steel plates, with the terminal outlet located at the lower part of the frame. The robust structure effectively withstands vibration and impact from mining equipment.
• 定子: The stator core is made of 0.5 mm low-loss silicon steel laminations assembled in a segmented structure, with ventilation ducts between core sections. The windings use formed double-layer short-pitch coils with Class B or Class F insulation, evaluated at Class B temperature rise to extend service life.
• 转子: Magnetic poles are fabricated from laminated steel plates and mounted together with the field windings on the rotor yoke. The field windings use Class B or Class F insulation.

Flexible Cooling System

The motor ventilation system can be open-type natural ventilation or totally enclosed duct ventilation, allowing users to select the most suitable cooling method according to actual site conditions.
