YBX4 Series 6-Pole Motor

The YBX4 Series 6-pole three-phase induction motor is a robust, high-torque solution engineered for industrial applications requiring reliable performance at lower rotational speeds. With a 6-pole configuration, it delivers a synchronous speed of 1,000 r/min (at 50 Hz) or 1,200 r/min (at 60 Hz), making it ideal for heavy-duty machinery such as crushers, mills, large conveyors, and low-speed pumps that demand sustained torque output 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 resistance to 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 reduces energy losses, achieving IE3/IE4 efficiency standards per IEC 60034-30-1, optimizing energy consumption and reducing operational costs.

Key advantages include outstanding starting torque, smooth acceleration, and minimal vibration, ensuring stable performance even under heavy or fluctuating loads. The motor supports a power range of 1.1 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 rugged design, ease of maintenance, and global certifications (IEC, NEMA), the YBX4 Series 6-pole motor is widely adopted in mining, cement, and material handling sectors, offering a cost-effective blend of efficiency, durability, and high-torque capability for low-speed applications.

The YBX4 series 6-pole motor (synchronous speed 1000 r/min) is a specialized explosion-proof drive component designed for low-speed, heavy-load industrial transmission, integrating seamlessly with reducer systems. Complying with IE4 ultra-high energy efficiency standards, it adopts a precision-optimized electromagnetic structure and reinforced mechanical design, delivering robust torque output at low rotational speeds while minimizing energy consumption for large-scale equipment.

A distinctive advantage is its outstanding low-speed stability and load adaptability. The 6-pole configuration maintains steady operation with minimal speed fluctuation under heavy loads, reducing mechanical impact on reducer gears and bearings and extending the overall service life of the transmission assembly. Its Ex db ⅡC T4 Gb explosion-proof rating ensures safe application in hazardous environments with flammable gases, dust, or vapors, such as mining sites, large chemical workshops, and heavy-duty material handling facilities.

Equipped with F-class insulation and IP55 protection, the motor resists moisture, dust, and high-temperature accumulation, maintaining reliable performance during long-term continuous operation. The optimized IC411 cooling system enhances heat dissipation efficiency, preventing overheating even under high-load conditions, while the standardized mounting interface enables flexible compatibility with various reducer models for diverse industrial scenarios.

Featuring low noise emission, minimal vibration, and durable construction, it reduces maintenance frequency and operational costs. Optional intelligent monitoring functions, including real-time temperature and load detection, further improve operational safety and controllability. This combination of low-speed torque, explosion-proof reliability, and energy efficiency makes it an ideal choice for reducer-motor assemblies in large pumps, crushers, and heavy-duty conveyor systems.
