These plants process large volumes of crushed stone, sand and gravel, relying heavily on fixed-speed motors for crushers, conveyor belts, vibrating screens and pumps. However, full voltage or direct on-line starting methods often cause mechanical stress, voltage drops and high inrush currents that lead to frequent breakdowns and operating inefficiencies.<\/p>\n<p><a href=\"https:\/\/benshaw.com\/motor-control-solutions\/low-voltage-motor-control\/soft-starters\/\">Soft starters<\/a>, by contrast, offer an efficient, cost-effective solution for controlling the acceleration of fixed speed equipment \u2013 reducing mechanical shock, enhancing reliability and lowering maintenance costs.<\/p>\n<h4><span style=\"color: #4d8cc7;\"><strong>Challenges of Fixed Speed Motors<\/strong><\/span><\/h4>\n<ul>\n<li><strong>High Inrush Currents<\/strong> \u2013 At startup, motors draw six to eight times their full load current. Excessive current draw during startup can increase energy costs.<\/li>\n<li><strong>Mechanical Shock<\/strong> \u2013 Sudden torque stresses belts, couplings and bearings. Repeated stress on motors and mechanical equipment increases maintenance costs.<\/li>\n<\/ul>\n<h4><span style=\"color: #4d8cc7;\"><strong>Key Benefits of Soft Starters in Fixed Speed Applications<\/strong><\/span><\/h4>\n<ul>\n<li><strong>Enhanced Crusher Performance and Longevity<\/strong> \u2013 Sudden applications of full voltage and torque cause significant mechanical stress on a crusher\u2019s\u00a0drive system. Soft starters gradually increase torque, reducing mechanical stress to belts, shafts and couplings.<\/li>\n<li><strong>Smooth Conveyor Belt Operation<\/strong> \u2013 Uncontrolled startups cause belt slippage, misalignment and excessive tension, leading to premature belt wear and roller damage. Soft starters provide gradual acceleration, preventing belt slippage and reducing disruptions to material flow.<\/li>\n<li><strong>Reduced Stress on Vibrating Screens<\/strong> \u2013 Vibrating screens operate under constant mechanical stress. High starting torque can lead to crack formation in screen decks, motor misalignment and increased vibration levels. Soft starters smoothly ramp up speed, preventing sudden shocks to the screw frame, bearings and drive motor.<\/li>\n<li><strong>Pump Protection and Water Hammer Reduction<\/strong> \u2013 Abrupt starts can cause water hammer \u2026 a damaging pressure surge that weakens pipelines and valves. Soft starters gradually increase pump speed during startup, reducing shock and providing a steady pressure buildup.<\/li>\n<\/ul>\n<p>Whether applied to crushers, conveyors or pumps, soft starters help increase reliability, reduce energy consumption and extend equipment life in fixed-speed aggregate applications. <a href=\"https:\/\/benshaw.com\/contact\/\">Contact our team today<\/a> to discuss the best motor control or drive solution for your application.<br \/>\n<img decoding=\"async\" class=\"alignright size-full wp-image-65881\" src=\"https:\/\/benshaw.com\/wp-content\/uploads\/2025\/03\/2025-World-of-Asphalt-Banner.jpg\" alt=\"World of Asphalt Show and Conference\" width=\"242\" height=\"180\" \/><\/p>\n<h4><span style=\"color: #4d8cc7;\"><strong>Join Us at the World of Asphalt Show and Conference<\/strong><\/span><\/h4>\n<p>Benshaw will be on hand March 25-27, 2025 at the <strong>2025 World of Asphalt Show and Conference (Booth #7032)<\/strong> in St. Louis, Missouri featuring our latest applied motor control products and technologies.
