Mining Motors for Combined Cutter-loaders

Product catalog summary

Application
The dSKgw series motors are designed for driving mining organs of combined cutter-loaders in harsh underground conditions, specifically in areas with methane and coal dust explosion risks.

Technical Description
These are three-phase induction motors with a squirrel cage rotor, featuring a horizontal design (IM3301) and explosion-proof construction with a flame-proof cover. They comply with electrical standards for group I devices and mining equipment standards.

Construction
The motors are fully enclosed with an IP55 protection rating. They include a main terminal box with stator winding and temperature sensor terminals. The frame and endshields are water-cooled, and the stator winding is made of copper wire with class H insulation. A de-clutching device is included for mechanical disconnection and overload protection.

Bearings
SKF roller bearings with LGHP2 grease are used, suitable for temperatures up to 150ºC. Specific bearing types are listed for different motor models.

Thermal Protection
Motors are equipped with thermal protection for both bearings and windings, including bi-metal thermal switches and Pt100 thermo resistors. Low voltage motors use PTC thermistors for additional protection.

Technical Parameters
The document provides detailed specifications for various motor models, including rated power, speed, torque, efficiency, and other performance metrics.

Environmental and Operational Conditions
The motors are suitable for explosive environments with specific atmospheric pressure, temperature, humidity, and dust conditions. Cooling water parameters are also specified.

Motor Delivery
Motors are delivered with grease in bearings, lifting eyes, a safety shaft, and other components. An instruction manual and declaration of conformity are included.

Dimensional Drawings
Dimensional drawings for various motor types are provided, illustrating the physical design and layout.
