1.1KW 2-Pole Three-Phase Induction Motor Introduction

This 1.1KW three-phase induction motor is a compact yet high-reliability industrial drive unit, defined by its 2-pole configuration and a rated speed of 2800 rpm—closely approaching the synchronous speed of 3000 RPM for 50Hz power supply, a key feature that ensures efficient electromechanical energy conversion and stable power transmission. Operating on the principle of electromagnetic induction, the motor utilizes a rotating magnetic field (RMF) generated by three-phase alternating current passing through the stator windings, which induces an electromotive force (EMF) in the rotor conductors, thereby driving the rotor to rotate with minimal slip ratio. Engineered with optimized electromagnetic circuit design, it achieves excellent energy efficiency (typically reaching IE2 or IE3 standards) and low noise emission, thanks to precision-balanced rotor assemblies and optimized air gap design that minimizes harmonic vibration during long-term continuous operation.

Constructed with industrial-grade materials, the motor features a robust cast-iron frame that provides superior mechanical rigidity and heat dissipation performance, complemented by high-purity copper stator windings with class F insulation—enhancing thermal endurance and extending the motor’s service life. The rotor adopts a squirrel-cage structure, a classic design for three-phase induction motors that offers high mechanical strength, low maintenance requirements, and reliable operation under variable load conditions. Precision sealed ball bearings are integrated to reduce frictional loss, while a corrosion-resistant surface treatment on the housing ensures adaptability to harsh working environments, such as high-humidity workshops, dusty agricultural fields, and outdoor municipal facilities, effectively resisting wear, chemical corrosion, and voltage surges.

Classified as a light-to-medium-duty motor, this 1.1KW 2-pole model is highly versatile and widely deployed across multiple industries. In mechanical processing, it serves as the core drive for small lathes, drilling machines, and packaging equipment, providing consistent torque output to ensure processing precision. In agricultural applications, it powers irrigation pumps, small grain conveyors, and ventilation systems for greenhouses, adapting to intermittent and continuous operation demands. For municipal engineering, it is commonly used in ventilation fans, small water treatment equipment, and garbage collection conveyors. Its compact structural design allows for flexible installation—either horizontal or vertical mounting—saving space in limited work areas, while the standardized output shaft ensures compatibility with various transmission components such as couplings, belts, and gears.

Under rated load conditions, the motor maintains a stable speed regulation performance with a low slip rate, ensuring consistent torque output for load-sensitive equipment. It also features a high power factor (typically above 0.85 at rated load), which reduces reactive power consumption, optimizes the power grid efficiency, and lowers long-term operational costs for users. To maximize performance and service life, proper operation and maintenance are essential: the motor must be operated within the specified voltage (380V for three-phase AC, 50Hz frequency) and ambient temperature range (-15℃ to 40℃), and regular maintenance should include cleaning stator windings to remove dust, checking bearing lubrication (using lithium-based grease), inspecting insulation resistance, and tightening terminal connections to prevent poor contact and overheating.

This motor complies with international industrial standards such as IEC 60034, featuring built-in overload protection potential when matched with appropriate motor protectors, which triggers shutdown in case of abnormal conditions such as phase loss, overload, or overheating, effectively preventing motor damage. It also meets environmental protection requirements with low electromagnetic interference (EMI) and no harmful substances in materials. Whether for small-scale production lines, auxiliary workshop equipment, or agricultural/municipal facilities, this 1.1KW 2-pole three-phase induction motor offers a cost-effective, reliable, and energy-efficient power solution, balancing performance, durability, and usability for diverse industrial and agricultural applications.
