YBX4 Series 8-Pole Motor
The YBX4 Series 8-pole three-phase induction motor is a specialized, high-torque solution engineered for industrial applications requiring reliable performance at exceptionally low rotational speeds. With an 8-pole configuration, it delivers a synchronous speed of 750 r/min (at 50 Hz) or 900 r/min (at 60 Hz), making it ideal for heavy machinery such as large-scale conveyors, ball mills, rotary kilns, and slow-speed pumps that demand sustained torque under demanding conditions. Constructed with a reinforced cast-iron frame, the YBX4 Series ensures exceptional durability in harsh environments, while its IP55 protection rating provides superior defense against dust, moisture, and contaminants. The motor features F-class insulation (rated for 155°C), enhancing thermal stability and extending service life during continuous or intermittent operation. Its optimized electromagnetic design minimizes energy losses, achieving IE3/IE4 efficiency standards per IEC 60034-30-1, reducing energy consumption and operational costs. Key advantages include unmatched starting torque, smooth acceleration, and low vibration, ensuring stable performance even under heavy or fluctuating loads. The motor supports a power range of 2.2 kW to 315 kW and voltage compatibility from 380V to 660V, accommodating diverse industrial requirements. Optional accessories like thermal overload protection and anti-condensation heaters enhance safety and reliability. With its compact yet robust design, ease of maintenance, and global certifications (IEC, NEMA), the YBX4 Series 8-pole motor is widely adopted in mining, cement, and metallurgical sectors, offering a cost-effective blend of efficiency, durability, and high-torque capability for ultra-low-speed applications.

The YBX4 series 8-pole motor (synchronous speed 750 r/min) is a specialized explosion-proof drive component engineered for low-speed, heavy-load industrial scenarios, seamlessly integrating with reducer systems to deliver stable and efficient power transmission. Adhering to IE4 ultra-high energy efficiency standards, it combines a compact electromagnetic structure with robust mechanical design, balancing high torque output and energy conservation for demanding equipment.
A distinctive advantage is its excellent low-speed stability and torque density. The 8-pole configuration generates substantial starting and running torque at low rotational speeds, minimizing mechanical impact on reducer components during load startup and operation, thus prolonging the service life of the entire transmission assembly. Its Ex db ⅡC T4 Gb explosion-proof rating ensures safe application in hazardous environments with flammable gases, vapors, or dust, such as coal mines, chemical plants, and grain storage facilities.
Equipped with F-class insulation and IP55 protection, the motor resists moisture, dust, and temperature fluctuations, maintaining consistent performance in harsh working conditions. The optimized IC411 cooling system enhances heat dissipation, enabling continuous 24/7 operation (S1 duty) without overheating, while the standardized mounting interface simplifies integration with various reducer models.
Featuring low noise emission, minimal vibration, and reduced maintenance requirements, it lowers long-term operational costs. Optional temperature monitoring and overload protection functions further improve operational safety. This combination of low-speed torque, explosion-proof reliability, and energy efficiency makes it an ideal choice for reducer-motor assemblies in material handling, metallurgy, and heavy machinery.
