A 400kW low voltage high power motor is an industrial drive tool with a 400kW rated output, running purely on low-voltage supply. It cranks out 400kW of robust power without any reliance on high-voltage systems - perfect for heavy-duty equipment, while cutting down the hassle of on-site power upgrades. It fits right into a wide range of industries, striking an ideal balance between raw power and versatility.
We offer tailor-made parameter settings for different working conditions. The motor locks in a steady 400kW rated power, with pole counts adjustable from 2 to 8 to suit various equipment speed requirements. It operates on a standard 380/660/440V low-voltage, 60Hz supply, eliminating the need for complicated high-voltage wiring. Boasting an IP55 protection class, it stands up to dust and low-pressure water splashes with zero impact on internal parts. The cooling type is IC411 self-ventilated, so the built-in fan efficiently dissipates heat and it can handle working conditions up to 45℃.
The attention to detail is really thoughtful: there are 6 PT100 temperature sensors in the winding, and 2 more on the bearings to monitor core component temperatures in real time; it comes with two 220V heating strips to prevent internal condensation in humid environments; it has a built-in auxiliary junction box for easy maintenance later, and the non-drive end uses insulated bearings to effectively prevent motor damage from shaft currents. These features aren't just thrown together-they're smartly designed to solve real industrial problems.

This 400kW low voltage high power motor set of parameters has three main advantages. First off, it's super adaptable. The 380/660/440V low-voltage setup hooks right up to most standard factory power grids-no need for extra high-voltage gear. Plus, the 2–8 pole adjustable feature fits the speed needs of all sorts of equipment, from fans and pumps to crushers. One motor can work for multiple production lines. Second, it's safe to operate. The IP55 protection rating lets it work reliably in dusty, humid workshops or even outdoors. Multiple PT100 temperature sensors act like a "thermometer," giving early warnings if there's a temperature anomaly, preventing overheating issues right from the start. Third, it's low maintenance. The self-fan cooling method doesn't require additional cooling systems, insulated bearings and heating strips reduce component wear, and the auxiliary junction box makes wiring easier during maintenance, greatly cutting down on manpower and material costs over time.

Parameters are like the 'skeleton' of a motor, but its self-protection features are the real highlight - this motor comes with a built-in 'safety manager' that actively adjusts its operation based on environmental changes.

During the humid plum rain season in southern China, when workshop humidity spikes, two 220V heating strips automatically kick in, raising the temperature steadily to drive out moisture inside the motor and prevent the insulation on the windings from aging. When the motor powers heavy-duty machinery at full load, 6 winding temperature sensors and 2 bearing temperature sensors keep a constant eye on data. If temperatures edge close to the warning threshold, the system kicks off an alert right away, nipping small glitches in the bud before they blow up into major headaches.

The insulated bearings on the non-drive end are a real game-changer, acting like an 'insulation shield' for the motor shaft that blocks shaft currents generated during operation. Although shaft current seems minor, it can seriously wear down bearings over time and shorten motor life. This design increases the motor's average time between failures by over 30%. With this proactive protection, the motor is no longer just a power device - it's a 'smart partner' that takes care of itself.
This 400kW low voltage high power motor perfectly meets industrial users' core needs for compatibility, safety, and maintenance convenience. Its low-voltage design lowers the entry barrier, comprehensive features ensure stable operation, and smart protection cuts down maintenance costs. It effectively solves the industry's pain points of 'hard-to-adapt, hard-to-maintain' high-power motors.
