What Is A Motor Inrush Current at Samuel Stapleton blog

What Is A Motor Inrush Current. When a motor is energised using an ordinary electromagnetic starter, it can draw an inrush current that’s up to ten times its normal running current. Why is motor inrush current so high? As the name suggests the term “inrush current” indicates that when a device is turned on during the initial stage a huge amount of current rushes into the circuit. Although commonly understood, this fact seems counterintuitive to common sense: Even the common formula relating torque, power, and rpm states: Inrush current, also referred to as “locked rotor current,” is the excessive current flow experienced within a motor and its conductors during the first few moments following the energizing (switching on) of the motor. Lower power on a fixed voltage source should equal lower current consumption. Slower motion (less work done over time) consumes less energy and, therefore, lower power. This sudden surge of current can damage the device. The inrush current is the highest peak current experienced in the system and can be twice or ten times the normal rated current. When an electrical device, such as an ac induction motor, is switched on, it experiences a very high, momentary surge of current, referred to as inrush current. And, particularly if the motor is.
