High efficiency motor inrush current

Web13 de fev. de 2013 · Motor applications are complex, because they’re inductive loads with a high-current demand at startup. Because this inrush is typically six times the running current, overcurrent protection for motor applications must differ from other equipment. You might be uncomfortable with some of the Art. 430 allowances for overcurrent protection. WebEfficiency: A conventional motor starter supply full voltage (very high inrush current) to the motor that consumes too much energy. A soft starter significantly reduces it & allows a gradual increase in energy consumption. Also the power switches are controlled using very low voltage level. It improves the overall efficiency of the motor.
