Which starter type is noted for being one of the least expensive options for large horsepower motors?

The Wye Delta Starter is recognized for being a cost-effective solution for starting large horsepower motors. This starter type effectively reduces the voltage applied to the motor at startup, which in turn decreases the initial inrush current and minimizes the stress on electrical components.

Using a Wye Delta configuration allows the motor to start in a wye connection, limiting the voltage and current drawn, before switching to a delta connection to operate at full capacity. This transition helps to manage the mechanical and electrical loads during startup, which can prolong equipment lifespan and lower operating costs.

Overall, the Wye Delta Starter presents an economical approach for managing large motor applications, balancing performance and cost, which is an important consideration for installations involving substantial horsepower.
