What happens to an electric motor's amp draw when the load increases?

When the load on an electric motor increases, the amp draw also increases. This is because the motor requires more electrical current to produce the additional mechanical power needed to overcome the greater load. The relationship between load and current is based on the power equation, where power is the product of voltage and current (P = V × I).

As the load increases, it demands more energy from the motor, and to satisfy this energy requirement, the motor draws more current. This increased current flow ensures that the motor can provide the necessary torque to handle the additional workload effectively.

In various scenarios with differing load conditions, you may notice that if the motor is operating close to its load capacity, the increase in amp draw can be significant. Understanding this relationship is crucial for applications involving electric motors since it helps in properly sizing circuit components and ensuring efficient operation.
