Brief Introduction

4 pole induction motor is the core power unit of this AIMIN YVF315L-4A variable frequency three-phase asynchronous motor, engineered and manufactured by Xi'an AIMIN Motor Co., Ltd. Designed for VVVF drive applications, this squirrel-cage asynchronous motor delivers stable adjustable speed performance for heavy-duty industrial scenarios. It complies with JB/T7118 industry standard and CE certification, making it a reliable choice for global industrial clients.

This model is rated at 185kW, 380V, 3-phase, with rated current of 329A and rated speed of 1485 r/min at 50Hz. Its rated torque reaches 1178 N·m. The motor supports a wide frequency range from 50Hz to 70Hz for constant power output, while maintaining constant torque operation within 5–50Hz. The protection class is IP55, cooling system IC416, and insulation class F (TH.CL.155), which ensures excellent thermal stability during long-time variable-speed operation. Two 6319/C3 bearings are fitted at both drive and non-drive ends, providing outstanding load capacity and low vibration performance. The B3 foot-mounted installation form fits most conventional mechanical transmission layouts.

As a robust 4 pole induction motor, it is specially optimized for inverter power supply. The electromagnetic design suppresses harmonic losses and torque ripple caused by variable frequency drives, avoiding overheating issues common in standard motors running with VFD. Low noise and low vibration characteristics enable continuous stable operation in tough working environments. The total weight of this unit is 1054kg, adopting high-strength cast iron frame structure to resist mechanical shock. It is widely applied in metallurgy, chemical processing, water pumps, fans, machine tools and conveyor systems for energy-saving speed regulation and automatic production lines.

The 4 pole induction motor stands out among variable-speed motor products for its balanced performance between torque and speed. Compared with 2-pole high-speed motors, it offers larger low-speed torque and smoother running; compared with multi-pole low-speed motors, it retains higher operating efficiency in medium speed range. AIMIN, a well-known Chinese motor brand, has decades of R&D and manufacturing experience. Every unit undergoes strict factory testing before delivery. The production batch of this YVF315L-4A was finished in August 2026.

In practical projects, users can pair this motor with matched frequency converters to realize flexible speed control, reduce startup impact and cut energy consumption. Thanks to IP55 dustproof and waterproof enclosure, it can work in workshops with dust and moisture. The simple structure brings convenient maintenance and long service life. This AIMIN variable frequency 4 pole induction motor integrates high power density, reliable variable speed capability and international compliance standards, serving as a preferred heavy-duty power solution for modern industrial drive systems.
