Why should three-phase asynchronous motors choose reduced vo

In industrial settings, the startup phase of electric motors plays a crucial role in ensuring system stability, energy efficiency, and equipment longevity. For three phase asynchronous motors, reduced-voltage starting is increasingly recommended, and Wolong Nanyang Motor is championing this method to enhance performance while protecting infrastructure.
When three phase asynchronous motors start at full voltage, they often draw a current that is six to eight times their rated load current. This high inrush can cause a sudden voltage dip in the power supply network, potentially disrupting sensitive equipment or triggering protective devices in adjacent systems. Reduced-voltage starting significantly lowers this initial current surge, minimizing the impact on the electrical grid.
One of the most effective benefits of reduced-voltage starting is the gentle mechanical acceleration it provides. Full-voltage starts apply immediate and maximum torque, which can strain gears, couplings, and driven loads. By contrast, starting methods such as soft starters, autotransformers, or star-delta connections help the motor ramp up gradually. This controlled acceleration reduces mechanical wear and tear, extending the lifespan of both the motor and the equipment it powers.
Wolong Nanyang Motor incorporates built-in compatibility for reduced-voltage starting across its latest line of three phase asynchronous motors. Their designs support integration with soft-start technology, ensuring low starting torque without sacrificing steady-state performance. These motors are ideal for high-inertia applications like compressors, pumps, and conveyors where abrupt starting torque could lead to system imbalances or mechanical damage.
Additionally, using reduced-voltage starting enhances energy efficiency. Although the energy saved during startup is brief, the cumulative effect across multiple start-stop cycles in continuous operation leads to measurable reductions in power consumption and operating costs.
Safety is also a key concern. Lower starting currents reduce the thermal stress on windings and internal components, preventing premature aging and lowering the risk of overheating or insulation failure. For companies focused on operational reliability and long-term asset protection, reduced-voltage starting is not just a best practice—it’s a strategic choice.
As global industries adopt smarter and more sustainable motor control systems, Wolong Nanyang Motor continues to innovate with high-performance solutions tailored for modern demands. Their three phase asynchronous motors, equipped with advanced starting features, reflect the brand’s ongoing commitment to efficiency, safety, and technological leadership.
