YBX4 Series 4-Pole Motor
The YBX4 Series 4-pole three-phase induction motor is a robust, energy-efficient solution tailored for industrial applications demanding reliable performance at moderate speeds. With a 4-pole configuration, it delivers a synchronous speed of 1500 r/min (at 50 Hz) or 1800 r/min (at 60 Hz), making it ideal for machinery such as conveyors, mixers, crushers, and general-purpose pumps that operate optimally at lower rotational speeds. Constructed with a durable cast-iron frame, the YBX4 Series ensures longevity in harsh environments, while its IP55 protection rating provides effective defense against dust and moisture ingress. The motor features F-class insulation (rated for 155°C), enhancing thermal stability and extending service life under continuous or heavy-duty operation. Its optimized electromagnetic design minimizes energy losses, achieving IE3/IE4 efficiency levels in compliance with IEC 60034-30-1 standards, reducing operational costs and environmental impact. Key advantages include high starting torque, low vibration, and quiet operation, ensuring smooth performance across varying loads. The motor supports a power range of 0.75 kW to 315 kW and voltage compatibility from 380V to 660V, accommodating diverse industrial requirements. Optional accessories like thermal overload protectors and space heaters enhance safety and reliability. With its compact design, ease of maintenance, and global certification (IEC, NEMA), the YBX4 Series 4-pole motor is widely adopted in manufacturing, mining, and HVAC sectors, offering a cost-effective blend of efficiency, durability, and versatility for medium-speed applications.

The YBX4 series 4-pole motor (synchronous speed 1500 r/min) is a high-reliability explosion-proof drive component optimized for reducer systems, featuring IE4 ultra-high energy efficiency and a robust mechanical structure to meet medium-speed industrial transmission demands. It integrates precision electromagnetic winding design and explosion-proof enclosure, forming a seamless and stable transmission assembly with reducers for diverse heavy-duty equipment.
A standout advantage is its balanced torque output and low vibration performance. The 4-pole configuration delivers consistent rotational stability, minimizing mechanical impact on reducer gears and bearings during startup and operation, thereby extending the overall service life of the transmission system. Its Ex db ⅡC T4 Gb explosion-proof rating ensures safe operation in hazardous areas with flammable gases or dust, such as petrochemical and coal mining industries.
Equipped with F-class insulation and IP55 protection, the motor resists humidity, dust, and continuous temperature variations, maintaining stable performance in harsh working environments. The optimized IC411 cooling system enhances heat dissipation efficiency, enabling prolonged continuous operation (S1 duty) without overheating, while the standardized mounting interface allows easy integration with various reducer models.
With low noise emission, energy-saving operation, and minimal maintenance requirements, it reduces long-term operational costs. Optional stator temperature monitoring further improves operational safety. This combination of stability, explosion-proof safety, and energy efficiency makes it an ideal choice for reducer-motor assemblies in metallurgy, material handling, and chemical processing.
