Low Voltage AC Motor

This line of Low Voltage AC Motors-replacing the old YE3/4/5 series-covers IE3, IE4, and IE5 efficiency classes. They're high-performance, energy-saving options for general industrial low-voltage power needs, and they meet all IEC standards and domestic GB regulations. Whether you' re looking for basic energy-saving upgrades or ultra-high-efficiency operation, these motors have you covered.

They're rated for 380V low voltage (we can customize to 400V/480V for overseas markets) and work with 50Hz or 60Hz frequency. Key features: F-class insulation, IP55 protection (keeps out dust and water splashes), and IC411 self-ventilation cooling.They're built for non-stop S1 continuous operation-compact and lightweight, super easy to install and maintain. And they run nice and quiet (≤75dB) with very little vibration, so they're perfect for workshops, factories, and light industry.

Efficiency classes in short:

IE3: Basic high-efficiency. Cuts 10% energy vs traditional motors. Good for basic industrial use, budget-friendly upgrade.

IE4: Better efficiency (with optimized design & high-grade materials). Cuts extra 8-12% losses. Saves more long-term.

IE5: Top ultra-high efficiency (up to 96.5%). Uses advanced design & low-loss parts to save energy. Perfect for 24/7 equipment (pumps, fans, compressors) in energy-sensitive places.

Applicable to: Conveyors, mixers, agricultural machinery, fluid machinery. Balances pro performance and practical use.

Their standardized sizes make them easy to swap out, and they offer reliable performance along with flexible customization options (voltage, frequency, mounting) that fit global industrial needs. Overall, they're versatile, energy-saving go-tos for modern low-voltage drives

1.Energy Saving

These Low Voltage AC Motors support both constant torque and constant power speed regulation modes, carry China's Energy Efficiency Labelling certification, and can be customised to meet specific industrial requirements. They represent a common industrial power solution balancing dynamic performance with energy efficiency benefits.

The core advantage of these motors lies in 'long-term cost savings through incremental efficiency improvements': progressing from IE3 to IE4 and then IE5, operational efficiency progressively increases while energy losses are continuously reduced. Take the 75kW 280S-2 model as a case: its IE3-rated (YE3) efficiency is 94.7%. If you step up to IE4 (YE4), efficiency climbs to 95.6%, while the IE5 (YE5) version pushes it to 96.5%.

If we calculate based on industrial equipment running at full load 24/7 (8,760 hours a year), the IE4 model cuts energy use by 5,965 kWh annually vs. the IE3. At the US industrial electricity rate of $0.13/kWh, that equates to roughly $775 in yearly savings. Over in Europe, with an industrial rate of €0.20/kWh, you'd save about €1,193 each year. Furthermore, IE5 models achieve an additional annual saving of 5,653 kWh compared to IE4 models. At US electricity rates, this equates to approximately $735 per annum, while at European rates, the annual saving amounts to roughly €1,131.

Mounting Type

The mounting type of Low Voltage AC Motor is accord with regulations of GB/T 997 Electric Motor Structure and Mounting Type Code.

Terminal Box of Motor

The position of the motor main power terminal box is at the top by default. The box opening is towards the right,and the terminal box can be mounted horizontally by rotating 180°.The terminal box connector is designed as per national standards. According to the motor current and the conditions of usage, the cable should be selected correctly. The diameter of the cable entry of the terminal box should match the diameter of the seal ring.
