Direct-Drive Top Drive Variable Frequency Permanent Magnet Synchronous / Asynchronous Motor

Direct-Drive Top Drive Variable Frequency Permanent Magnet Synchronous / Asynchronous Motor

This motor is specifically developed for the direct-drive top drive system of electric drilling rigs. Serving as the drive motor for the direct-drive top drive unit, it directly drives the central shaft to rotate the drill pipe for drilling operations.

Product Features:

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

• Vertical mounting configuration with double shaft extension and three-bearing support structure.

• Patented technologies are applied to the bearing load-bearing structure, the connection structure between the squirrel-cage end rings and guide bars, and the coupling between the rotor and the central shaft. 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.

• Low speed, high torque, wide constant-power speed regulation range, and strong overload capacity.

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