\nShaft damage during handling or bearing installation.<\/p>\n<\/li>\n<\/ul>\n
A servo motor shaft is designed for precision and strength, but it can fail due to overload, misalignment, fatigue, poor installation, or thermal\/electrical stress. Preventive maintenance, proper alignment, and using the right coupling can drastically reduce the risk.<\/p>\n","protected":false},"excerpt":{"rendered":"
Why a servomotor shaft can break? A servomotor shaft can break due to a variety of mechanical, operational, or installation-related causes. Below are the most common reasons, categorized for clarity: 1. Mechanical Overload Excessive torque beyond design limits can shear the shaft. Sudden impact loads (e.g., emergency stops or collisions in CNC machines). Repeated shock loading or high-inertia starts\/stops without proper ramping. 2. Misalignment Misalignment between the motor shaft and the driven load (e.g., gear, coupling, pulley) causes: Uneven stress distribution Shaft bending or fatigue over time Common in poor mounting or incorrect installation practices. 3. Fatigue Failure Cyclic stress over time, even if below yield strength, can cause crack initiation. Common in applications with frequent reversals or load fluctuations. Stress concentration points, such as keyways or sharp corners, accelerate fatigue. 4. Improper Coupling Using rigid couplings in applications needing flexible ones transmits undue stress to the shaft. Misuse of couplings that don\u2019t accommodate slight misalignments or thermal expansion. 5. Sudden Stops or Faults in Drive System Servo drives that lack proper deceleration profiles or safety braking mechanisms may induce shock torque. Electrical faults causing uncontrolled motion or jamming can snap the shaft. 6. Poor Maintenance or Repair Practices…<\/p>\n","protected":false},"author":3,"featured_media":10046,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[44],"tags":[],"class_list":["post-10045","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-servo-motor-en"],"yoast_head":"\n
