DRN180L4 SEW Motor 22 kW IE3 4-Pole TEFC Asynchronous

SEW-EURODRIVE DRN180L4 IE3 Motor | 22 kW, 400 V, 4-Pole, TEFC

Now, the Model DRN180L4 is a high-output IE3 motor from SEW-EURODRIVE. It makes 22 kW at 400 V, 50 Hz. Also, this 4-pole unit runs all day (S1). So, it fits tough plant drives. The DRN.. series is the IE3 update. It swaps out the old DRS../DR2S.. line. And, it is still built today.

Install Steps

• First, fix the motor to a solid, flat base. Use IM B35 foot and flange mount as standard.
• Then, align the shaft with the load. Keep radial and axial stress low.
• Next, wire the supply per the nameplate. Check the star/delta link for your voltage.
• Also, keep the fan and fins clear. Air must move free to cool the motor.
• Moreover, use cable glands that hold IP55. Seal every opening well.
• Last, for VFD use, follow VPWM rules in IEC 60034. Pick a drive that matches 38.5 A.

Setup and Care Made Simple

• The terminal box opens wide for easy wiring. Turn it in 90° steps for cable entry.
• Bearings come greased for life in most cases. No extra lube for normal work.
• Check insulation resistance now and then. Dry the windings if they get damp.
• Look at the fan cover every 6 months. Clean it if dust builds up.
• Check vibration and coupling once a year. Fix odd noise or heat fast.
• For wet or cold spots, add a space heater. It stops condensation when idle.

Works With

• Standard 400 V, 50 Hz three-phase power. Also 230/400 V or 400/690 V after rewire.
• Line and inverter duty (VPWM). Use SEW drives or equal VFDs for speed control.
• IM B35, IM B3, IM B5, and IM B14 mounts. Adapter flanges come on request.
• Many SEW DRS../DR2S.. installs. Just check shaft and flange size.
• Common gear reducers from SEW and other brands. Match torque and speed first.

Approvals

• IE3 Premium Efficiency per IEC 60034-30-1.
• Insulation class F (155) per IEC 60034-1.
• Cooling IC 411 per IEC 60034-6.
• IP55 per IEC 60034-5. IP66 on request.
• S1 continuous duty per IEC 60034.
• CE marked and meets EU rules.

Expert Review

So, the SEW DRN180L4 is a top pick for heavy plant work. Its IE3 class cuts power bills. Plus, the TEFC shell takes dust and wet air. With 142 Nm and 1477 rpm, it runs big conveyors, pumps, and mixers well. The motor stays cool and quiet. Inverter duty adds speed range. So, if you want a tough, low-care motor for non-stop work, this one fits. Just note the 170 kg weight for your mount plan.

Manager’s Insight

Also, we see strong pull for the DRN180L4 in food lines and heavy packing gear. Buyers like the IP55 shell and IE3 power savings. Plus, the star/delta swap helps in world markets. Stock is fine, but custom flanges take time. So, pick the IM B35 to get 12-24 hour ship. Pair it with a SEW VFD for top results. Thus, this motor rarely comes back for repair.

Best Equipment and Uses

• Belt conveyors and bulk material flow systems.
• Pumps for water and heavy fluids.
• Mixers and agitators.
• Fans and blowers.
• Compressors and extruders.
• Packaging and textile machines.
• Any long-run job that needs 22 kW at 400 V.

FAQ

Q: Can this motor run on a 480 V supply at 60 Hz?
A: Yes, but you must derate. At 60 Hz, speed goes up to about 1774 rpm. Voltage must stay in the V/Hz ratio. Ask SEW for the right limits.

Q: Is the DRN180L4 a direct swap for an old DRS180 motor?
A: Often yes, but not always. Shaft size and flange holes can differ. Check the SEW dimension sheet first. Do not force a fit.

Q: How do I stop condensation inside the motor?
A: Use a space heater or anti-condensation heater. Run it when the motor is off. This keeps windings dry in humid or cold sites.

Q: What VFD current rating should I pick for this motor?
A: Use a drive rated for at least 38.5 A. For heavy starts, go one size up. Shielded cable cuts electrical noise.

Q: What does the 12-month warranty cover?
A: It covers factory defects for 12 months from delivery. It does not cover wear, misuse, or wrong wiring. Keep the invoice for claims.

Q: How fast do you ship, and by which courier?
A: Stock items leave in 12-24 hours. We use FedEx, UPS, or DHL. You get a tracking number. Contact sales@powergearx.com for stock checks.

Buying Guide

• First, check your voltage and frequency. Most units come set for 400 V, 50 Hz in delta.
• Then, look at the mount. IM B35 is most common. Measure your flange and bolt holes.
• Next, match shaft size and keyway. Standard shaft is 48 mm with a 14 mm key.
• Also, for VFD use, pick a drive rated for 38.5 A or more. Use shielded cable.
• Plus, think about heat and height. Over 40 °C or 1000 m, derate or ask for a special build.
• And, buy spare gaskets and glands for wet spots.
• Last, always buy from a real dealer. Powergear X Automation Limited sells true SEW motors with full warranty.
