YQ 138-8AG 50Hz 3 Phase Asynchronous Low Speed Motor

Brief Introduction

Meet the YQ138-8AG: a workhorse three-phase asynchronous low speed motor from Xi'an SIMO Motor Co., Ltd., a trusted name in industrial electric equipment. Built for non-stop industrial use (S1 continuous duty), this low speed motor is engineered to power critical machinery in settings like factories, mining sites, or large-scale infrastructure projects.

Designed to fit standard industrial power setups (380V, 50Hz), it delivers steady, consistent power at 735 rotations per minute-perfect for driving equipment that needs reliable, moderate-speed operation, such as large pumps, conveyor belts, or ventilation fans. What sets it apart is its adaptability: it functions smoothly in temperatures ranging from -15°C (cold, high-altitude regions) to 40°C (hot, humid worksites), and even performs reliably at elevations up to 3800 meters-making it a solid choice for projects in mountainous areas.

Built to last, it features durable Class 155 insulation (protecting internal components from heat and wear) and heavy-duty bearings, ensuring long service life even under constant use. Weighing 1910kg, it's a robust, stable unit that meets GB/T 755 (a core Chinese industrial standard) and carries CE certification, aligning with European safety and quality benchmarks.

Whether you need to keep a production line running or power heavy mechanical systems, the YQ138-8AG low speed motor balances straightforward functionality, toughness, and adaptability-making it a dependable backbone for industrial operations.
