18.5kw 25HP 37A 3 Phase 380V Motor Protection Soft Starter

Product Description

Product Description

VH100 series motor soft starter  Motor Protection Starter

No contactor required, small volume,easy transportation and installation,reduce the shipping cost.

We strongly recommend VH100 type of motor soft starter for small power motor (especially for 5.5/7.5/11/15/18.5/22/30/37/45kw motor)

This series motor soft starter is a new type start-up equipment which integrates electric force and electronic techniques,computer technique and modern control -theory.

It is the new generation product to replace the conventional Star-delta Starter,

Self-coupling voltage-drop Starter and Magnetic control voltage-drop Starter.

Our motor soft starters are widely used in thermal power generation, hydropower, transmission and distribution equipment, metallurgy, chemical industry, mining, construction and other industries.

The compressor uses current limiting to realize smooth start, reduce motor heating and prolong service life. The belt conveyor realizes smooth and gradual starting process through soft starting to avoid product movement and material overflow.

Application

 

Pump: make use of soft stop function to relieve the influence of water hammer so as to save system maintenance cost.
Ball mill: make use of voltage ramp startup to reduce gear torque friction so as to save cost and time.
Fan: reduce belt friction and mechanical conflict to save maintenance cost.
Compressor: make use of current limitation function to realize smooth startup so as to reduce motor heating and prolong its service life.
Conveyor: make use of soft start to realize smooth and gradual startup process in order to avoid product move and liquid overflow.

Company Profile

 

Zhejiang Lingshine Electric Co., Ltd, a softstarterpro in China. Located in Liushi Town, Yueqing, Wenzhou, a region widely recognized as China's manufacturing hub for low voltage electrical products. Surrounded by a mature industrial supply chain, our core product lines include motor soft starters, SCR power controllers, and VFD drives, supported by a full range of thyristor and rectifier modules and solid state relays.

Founded in 2015, our facility covers 1,200 square meters, combining engineering design, production, and technical support under one roof. We built our business around solving three problems that cost customers time and money every day.

Motors that start too abruptly damage bearings, belts, and gearboxes over time. Our soft starters control the acceleration curve, protecting your equipment and extending its service life.
Heating and power regulation processes that lack precise control lead to inconsistent output, overheating, and shortened element life. Our SCR power controllers use phase-angle and zero-cross control to keep output stable and predictable, protecting your heating elements and improving product consistency.
Motors running at fixed speed regardless of actual load waste energy and add unnecessary mechanical stress. Our VFD drives adjust motor speed to match real demand, reducing energy costs and wear across pumps, fans, and conveyor systems.

Beyond standard products, we design and build complete panels, including soft starter cabinets, VFD cabinets, and temperature control cabinets, engineered to your wiring diagram and site conditions. This means you get one supplier for the full system instead of sourcing components separately and coordinating the integration yourself.
We maintain large in-stock inventory, allowing prompt delivery without long factory lead times. Our products are ISO 9001 certified and CE compliant, sold globally under the Aigoodele brand to customers across Europe, the Middle East, Southeast Asia, and other international markets. Our engineering team assists you from model selection through commissioning, so technical questions get answered by people who build these products, not just sell them.
