In this episode of the ABB Solutions Podcast, host Mike Murphy is joined by Robert Boyce, ABB U.S. Division Manager for IEC Low Voltage Motors, to discuss how motors are designed to perform in aggressive applications like crushers in the aggregate industry.

From heavy shock loads to extreme environmental conditions, crushers push motors to their limits. Robert shares how ABB designs motors to handle high starting torque, mechanical stress, vibration and contamination, all while maintaining reliability and efficiency.

Tune in to hear insights on:

• Aggregate Applications: How conveyors, shaker screens and crushers impact motor performance
• Starting Torque Demands: Why constant torque applications require higher locked rotor torque and overload capability
• Overbuilt Design: How larger shafts, reinforced materials and oversized bearings handle shock loads
• Vibration and Mechanical Stress: Why conduit box placement and internal components matter in aggressive environments
• Environmental Protection: How IP66 designs help protect against dust and moisture
• Electrical Reliability: Why terminal blocks provide stronger connections than flying leads in high vibration settings
• Efficiency Standards: How these motors meet and exceed IE3 and IE4 efficiency requirements
• Built for Survivability: Why durability and uptime are critical in crusher applications
