What Can Cause A Motor To Overload: Common Culprits And Solutions

An overload fault occurs when a motor draws an excessive amount of current, sometimes reaching up to six times its rated current. This typically happens due to an excessive load placed on the motor, causing it to work harder than it’s designed for. To prevent damage and ensure the safe operation of systems, overload protection relays are employed. These relays monitor the current flow to the motor and, when they detect an abnormal increase, they swiftly disconnect power to safeguard the motor and the overall system from potential harm.

“Why does my electric motor keep overloading?” This common issue, known as electrical overload, occurs when an electric motor draws excessive current, leading to various operational problems. One primary cause of electrical overload is a low supply voltage, wherein the motor compensates by drawing more current to maintain its torque output. Additionally, short-circuited conductors within the motor or an excessive voltage supply can also contribute to overload situations. Understanding these factors is essential for diagnosing and addressing motor overload problems in order to ensure efficient and safe operation. [Date: May 16, 2018]
