Brief Introduction

The YVF280S-4 unit comes with a nominal power output of 75kW, 380V operating voltage, rated current of 139A and a fundamental rotational speed of 1488 r/min. Configured with delta winding connection, IC411 self-circulation cooling design, IP55 protection grade and Class F insulation system, this motor demonstrates strong resistance to dust, moisture and accidental water splashing, making it well-suited for general factory operating environments. Equipped with 6317/C3 drive-end bearings and 6314/C3 non-drive-end bearings, it achieves premium dynamic balance, effectively suppressing vibration and noise during prolonged continuous running. Adopting IM B3 horizontal mounting arrangement, it supports flexible installation and serves as an optimal drive for fans, pumps, conveyors and other process machinery requiring variable-speed regulation.

Against the backdrop of industrial pursuit of precise motion control and energy-efficient operation, the elaborately optimized architecture of the 75kw elektromotor addresses core pain points under variable-frequency operating conditions. Generic motors face prominent risks of insulation degradation and overheating when powered by inverters due to harmonic interference. The YVF series enhances the winding's anti-corona capability and integral mechanical stiffness to withstand harmonic distortions generated by frequency converters. Stable constant-torque characteristics within the defined frequency range guarantee consistent and predictable load performance, reducing unplanned outages and lowering long-term maintenance investment for end customers. Each finished motor undergoes rigorous no-load commissioning, insulation testing and vibration inspection before dispatch to maintain consistent quality criteria.

SIMO adopts full-spectrum quality management covering raw material screening, machining monitoring and final product verification. Drawing on decades of proficiency in manufacturing industrial asynchronous motors, the brand achieves a fine balance between reliable performance and attractive pricing, offering responsive technical guidance and after-sales support for overseas distributors and end users. Compared with imported alternatives, SIMO YVF variable frequency motors deliver superior cost-effectiveness without compromising operational stability.

For newly built production lines and equipment renovation projects that demand reliable variable-speed drive power, the 75kw elektromotor acts as a resilient and cost-efficient driving option. It facilitates accurate speed adjustment, cuts overall energy consumption and boosts operational productivity. Backed by refined craftsmanship and field-verified reliability, SIMO YVF series motors have earned widespread recognition from industrial partners worldwide, establishing itself as a trustworthy variable-frequency driving solution for versatile mechanical transmission systems.
