← TechnologyWhich outcome arises when single-phasing occurs in a three-phase induction motor driving a conveyor belt system?
A)Reduced motor torque alongside rising temperature✓
B)Increased conveyor speed due to voltage imbalance
C)Synchronized motor operation among multiple units
D)Improved power factor reducing energy consumption
💡 Explanation
When single-phasing occurs, the induction motor loses one phase, and the remaining phases must carry the full load, causing increased current and thus higher temperature; simultaneously torque reduces. Therefore the motor experiences reduced torque and overheating, rather than increased speed, synchronization, or improved power factor, which necessitate balanced three-phase operation.
