A fan runs well during operation. But what happens when it stops?

In ventilation systems, a fan may continue rotating โ€” or even rotate backwards โ€” after shutdown if airflow from other fans or connected ducts drives the blades.

This matters when selecting and configuring a motor-drive system.

Three conditions deserve attention:

๐Ÿ”น The actual load โ€” Airflow and system pressure can affect how the fan behaves after shutdown.

๐Ÿ”น The stopping process โ€” The fan's inertia and external forces may influence its deceleration.

๐Ÿ”น The next start โ€” If the fan is still rotating, the drive's ability to handle a rotating motor and the application's restart requirements need to be checked.

For motor and VFD applications, reliable operation means looking beyond steady-state performance. Stopping and restarting conditions matter, too.

National Day is a moment to look back at how far we have come โ€” and to look ahead to where the journey may take us next.

Over the decades, Chinaโ€™s industries have grown, evolved, and reached further into the world.

LAEG has been part of that journey for more than 55 years, growing from motor manufacturing to providing motor and drive solutions for industrial applications in global markets.

Different generations.
Different technologies.
Different destinations.

But one continuous journey forward.

How much difference can a motor replacement make? โš™๏ธ

In one pulp pump application, a 200 kW YE2 asynchronous motor was replaced with a 200 kW TYP permanent magnet synchronous motor.

The project records show the following electricity consumption over two 14-hour operating periods:

๐Ÿ”น Before: 3,022 kWh
๐Ÿ”น After: 2,315 kWh
๐Ÿ”น Difference: 707 kWh โ€” approximately 23.4% lower consumption

For plant teams considering a retrofit, measuring existing energy use alongside the pumping duty is a useful first step toward evaluating potential savings.

These figures reflect this specific project. Comparisons should account for operating conditions, load and process requirements.

Two machines reach the same overload peak.

One runs normally.
The other trips after repeated cycles.

Why?

Because overload capability is not just about how high the load goes.

It also depends on how long the overload lasts and how much recovery time the system has before the next peak.

For repetitive machinery, two duty cycles can have:

๐Ÿ”น the same peak load
๐Ÿ”น the same overload duration
๐Ÿ”น but very different intervals between peaks

And that difference can change the result.

This is why an overload rating should not be read as a percentage alone.

When selecting or checking a motor and drive for cyclic applications, look at the complete duty cycleโ€”not just the highest load point.

Same peak. Different cycle. Different operating result.

Why use a PMSM + VFD for textile exhaust fans?

Textile workshops usually need ventilation systems to run for long hours, often in dusty environments.

For this application in Pakistan, the exhaust fan is driven by a LAEG TYP permanent magnet synchronous motor and an LD350E inverter.

The logic behind the combination is simple:

โ€ข PMSM: lower rotor losses and better efficiency for long-running operation
โ€ข V/F control: adjusts fan speed according to ventilation demand
โ€ข Integrated drive: motor and inverter are matched as one system

For ventilation equipment, the fan is only part of the story.

How the fan is driven also affects efficiency, flexibility, and long-term operation.

The drive runs normallyโ€”but trips on overvoltage during deceleration. โš™๏ธ

One possible reason: regenerative energy.

When a high-inertia load slows down, it can drive the motor into generating operation. Energy then flows back into the drive, raising the DC-link voltage.

So before treating it as a supply-voltage problem, check:

๐Ÿ”น Does the alarm occur mainly during ramp-down?
๐Ÿ”น Is the deceleration time too short for the load?
๐Ÿ”น If fast stopping is required, can the system handle the regenerative energy?

When the process allows it, a longer deceleration time may help.

The key question is not only โ€œ๐–๐ก๐ฒ ๐ข๐ฌ ๐ญ๐ก๐ž ๐ฏ๐จ๐ฅ๐ญ๐š๐ ๐ž ๐ก๐ข๐ ๐ก?โ€
