  • AN INVESTIGATION OF CAUSES OF FAILURES OF INDUCTION

    crusher software, most of the failures are passed off because of failure of bearing, winding harm, shaft failure, foot breakage & dust ingress affecting cooling of motor. If we're able to conquer these failures of crusher application motor, then it's going to genuinely enhance the existence & output

  • 800HP Crusher Electric Motor Repair Case Study

    2/28/2017· In 2006 the utility came to HECO after years of repetitive failures circling around the electric motor's rotor. This was originally presented at the Reliability, Process, and Maintenance (RPM) Symposium on Sep 13-14, 2016. Coal Crusher Electric Motor Rotor Case Study YouTube. HECOAllSystemGo.

  • Chapter 2 Induction Motor and Faults

    the most vulnerable parts for fault in the induction motor are bearing, stator winding, rotor bar, and shaft. Besides due to non-uniformity of the air gap between stator-inner surface and rotor-outer surface motor, faults also occur. Different studies have been performed so far to

  • Rotor bar melt down Electric motors & generators

    11/1/2012· This motor failed due to open rotor bars after several years of service in June. The bars on the failure in June were at the end ring connection point and appeared to be from fatigue. The rotor was re-barred by a rotor re-bar facility, after about four months of service it failed again.

    DO NOT FREE-REV MOTOR! Free-running your brushless motor in a no-load condition can cause rotor failure & ESC transistor damage that will not be covered by the product’s warranty. Because of the potential danger of overheating and ESC/motor damage and failure, you must start with VERY small pinion sizes and check the speed

  • The Common Failures of Hammer Crushers JXSC

    The problems caused by the imbalance of the hammer crushing motor cone are: (1) The moving cone produces an eccentricity, which changes the force state of the rotor to make it unevenly stressed. During the rotating motion, the moving cone repeatedly bends. When the fatigue limit is reached, damage or even breakage may occur.

    vibrating screen motor rotor fractured at bearing journal shoulder (rotor side). set-up of the system installation is shown in one of the pics. motor is mounted on a rigid frame that is mounted to the ground while driving a vibrator through v-belts. my initial assessment is that during vibration, the v-belts exert a radial force on the shaft and due to the motor's rigid mounting it will eventually fail due to the forces.

  • Impact Crusher an overview ScienceDirect Topics

    The impact crusher (typically PE series) is widely used and of high production efficiency and good safety performance. The finished product is of cube shape and the tension force and crack is avoided. Compared with hammer crusher, the impact crusher is able to fully utilize the high-speed impact energy of entire rotor.
