The AVH10-G series 3-phase motor soft starter is a compact and efficient solution designed for small to medium-power motors (5.5kW–37kW), eliminating the need for an external contactor to simplify installation. Its space-saving design reduces shipping costs while advanced electronic control ensures smooth, surge-free starts—protecting motors from excessive heat and mechanical stress. Ideal for compressors, conveyors, pumps, and fans, it reliably replaces traditional star-delta and auto-transformer starters across industries like power generation, mining, and construction. By enabling gradual acceleration, it prevents belt slippage, material spillage, and equipment wear, making it a cost-effective upgrade for both performance and longevity.

Applications

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.


Others: Electric motor / Water storage / Ventilator / Food mixer / Air compressor / Conveyors / Stone crusher / Pulverizer / Heavy-duty machinery and equipment
