Direct-Drive Variable Frequency Permanent Magnet Synchronous / Asynchronous Motor for Drawworks

This series of motors is developed for direct-drive applications in electric drilling rigs, including the rotary table, drawworks, and mud pumps, providing variable-frequency speed regulation via permanent magnet synchronous or asynchronous motor technology.

Product Features:

• Designed, manufactured, and tested in accordance with GB/T 23507.1-2017 and SY/T 6919-2020 standards.

• Patented technologies are applied to the bearing load-bearing structure and the connection structure between the squirrel-cage end rings and guide bars in asynchronous motors, while the permanent magnet synchronous motor features a high-performance rare-earth permanent magnet rotor structure.

• The motor incorporates an advanced anti-corona insulation structure.

• Designed to meet increased-safety (Ex e) explosion-proof requirements.

• High torque, compact size, wide constant-power speed regulation range, and strong overload capacity.

• Maintenance-free operation, high reliability, and low noise.
