Challenge

A global manufacturer of electric mining shovels required a reliable performing motor for their dipper system. Mining shovel owners and manufacturers require a dipper trip control system that works consistently with low maintenance.

Application requirements:

• High peak torque, extreme duty cycles and operation in critical environments
• Explosion proof, UL & ATEX required
• Efficient and energy sound solutions include power density and thermal management
• Flexibility for custom application solutions i.e., mounting flexibility, custom flanges, holding brake, etc.
• Fast response across speed range
