Flange Motor Mount Basics
What Is a Flange Motor Mount
Flange motor mounts are used in machines that need strong support. They help keep the motor lined up right. The flange face is flat and smooth. This lets you bolt the motor straight to the machine. The mounting holes let you use bolts to hold the motor tight. The alignment system keeps the motor in the right spot. This stops problems when the machine is running.
Here is a table that shows what makes flange motor mounts special:
Key Component | Description |
|---|---|
Flange Face | Flat, smooth surface for bolting the motor to equipment |
Mounting Holes | Let you use bolts to hold the motor tight |
Alignment System | Keeps the motor lined up to stop problems |
Flange motor mounts can be made from many materials. Steel is strong and lasts a long time. It is good for heavy loads. Aluminum is light and does not rust easily. This helps the motor last longer and saves fuel. Cast iron is good at stopping shaking and holds up heavy engines. Rubber cuts down on shaking and makes less noise. Polyurethane lasts a long time and does not wear out fast. It is good for high-performance jobs. Titanium is strong and does not get damaged by heat or chemicals.
Tip: YNF Rubber makes flange motor mounts you can trust for many jobs.
Applications of Motor Mounts
Motor mounts are used in many machines and industries. You see them in pumps, fans, conveyors, and compressors. Flange motor mounts help cut down on shaking and keep the motor steady. You find them in factories, cars, and even some home machines.
Motor mounts can hold loads from 20kg up to 5,000kg. This means you can use them for small or big jobs. They help stop shaking, which protects your machines and saves money. You pick the right motor mount by looking at the load, how much shaking there is, and where it will be used. For wet or chemical places, aluminum or stainless steel is best. For heavy engines, steel or cast iron is strong enough.

Preparation
Check Motor Specs
Before you start to install motor mounts, you need to check the motor specs. Look at the type of motor and the size. Make sure the mount fits the motor. Always check the mounting codes, like NEMA or IEC, to match the right position. Use a level to see if all mounting points are on the same plane. If the motor is not level, use shims to fix it. Check the load capacity of the mount. The mount must hold the weight of the motor and any extra parts. You should also look at the space around the motor. Make sure there is enough room for other parts you may need to add later. Good alignment helps the motor run smooth and keeps the motor mounts from wearing out too fast.
Tip: Always double-check the mounting position and codes before you start. This step helps you avoid costly mistakes.
Assess Mounting Surface
You need to look at the surface where you will put the mount. The surface must be flat and strong. If the surface is weak, the mount will not hold the motor well. Check for cracks or rust. Clean the area before you start. The material of the surface matters too. Steel and concrete work best for heavy motors. For lighter motors, you can use aluminum or wood, but make sure the mount is tight. If you see any damage, fix it before you put on the mount. A good surface keeps the motor mounts steady and safe.

Installation Steps
Position Flange Motor Mount
Start your mount installation by placing the flange motor mount in the correct spot. Make sure the mount sits flat on the surface. Use a base plate for flange mounts if you need extra support or want better vibration isolation. The base plate helps spread the load and keeps the mount steady. Check that the motor sits level from side to side. You also need to tilt the motor down at a 3-degree angle toward the back. This angle helps with cooling and reduces stress on the motor mounts.
Use this table to guide your alignment and load checks:
Step/Consideration | Description |
|---|---|
Check Total Indicator Runout | Use a dial indicator to measure TIR on both the compressor and motor shafts to ensure alignment. |
Address Soft Foot Conditions | Shim the motor and compressor feet to avoid soft foot issues. |
Ensure Proper Coupling Gaps | Make sure the coupling has a gap and does not touch, allowing for proper operation. |
Machining of Flanges | Check that flanges are flat and properly aligned. |
Use of Shimming | Use shims if needed to get the right alignment and load distribution. |
Tip: Good alignment and the right angle help with vibration isolation and make your mount installation last longer.
Drill and Align Holes
After you position the flange motor mount, mark the spots for drilling. Use a marker or punch to show where each hole goes. Make sure the holes line up with the mount and the flange. The holes must match the bolt pattern on the mount. Drill straight down to keep the mount stable.
Follow these best practices for drilling and aligning holes:
Best Practice | Description |
|---|---|
Proper Alignment of Flanges | Keep flange faces parallel and aligned to prevent stress. |
Piping Alignment | Align piping sections to avoid misalignment and extra stress. |
Bolt Insertion | Insert bolts through flange holes for even distribution. |
Hand Tightening | Hand-tighten bolts in a crisscross pattern for even pressure. |
Torque Wrench | Use a torque wrench to tighten bolts to the right strength. |
Crisscross Pattern | Tighten bolts in a crisscross pattern for even pressure distribution. |
Check that the holes are clean and free of debris. Clean holes help the bolts fit tight and keep the mount secure.
Secure with Bolts
Now you can secure the flange motor mount with bolts. Insert the bolts through the holes in the mount and flange. Use nuts on the other side if needed. Start by hand-tightening each bolt. Use a crisscross pattern to spread the pressure evenly. This keeps the mount from twisting or bending.
Next, use a torque wrench to tighten the bolts to the right strength. The table below shows some common torque values:
Motor Type | Bore Diameter (mm) | Thread | Tightening Torque (Nm) |
|---|---|---|---|
23IP | 5 | M5 | 3 |
34IP | 6.5 | M6 | 6 |
Check your motor’s manual for the exact torque needed. Tight bolts keep the mount installation safe and stop the motor from moving during use. Even pressure on all bolts helps with vibration isolation and keeps the motor mounts from wearing out too fast.
Set Correct Angle
You must set the correct angle for the flange motor mount. Use a level to check that the motor is flat from side to side. Tilt the motor down at a 3-degree angle toward the back. This angle helps oil drain and keeps the motor cool. It also helps the mount last longer.
The angle of installation for flange motor mounts significantly impacts the performance and longevity of the motors. Proper mounting minimizes vibration, enhances cooling, and ensures accurate alignment, all of which contribute to the overall efficiency and lifespan of the motor systems. Misalignment and poor mounting can lead to increased wear and instability, particularly in high-speed applications.
If you need to adjust the angle, use shims under the mount. Shims help you get the exact tilt you need. Always double-check the angle before you finish the installation.
Final Checks
Before you start the motor, do a full check of your mount installation. Look for any loose bolts or tools left near the mount. Spin the motor by hand to make sure it turns freely. Listen for any strange sounds. If the motor feels stuck or makes noise, stop and check your work.
Inspect the entire assembly for any loose components or tools in the vicinity.
Check how easily the motor spins; it should rotate freely without resistance or unusual sounds.
Briefly power on the motor for a test run to ensure proper functionality and response to control inputs.
If everything looks good, your flange motor mount installation is complete. You can trust your work to hold up under load. For the best results, use quality motor mounts from YNF Rubber. Their products help you avoid problems and keep your machines running smoothly.

Common Engine Mount Mistakes
Incorrect Techniques
Some people think putting in an engine mount is easy. But if you use the wrong way, you can have big problems. Many people hurry or skip steps. If you do not follow the right steps, the engine mounts can break early. Bad ways of installing can cause:
Engine mounts to break too soon
Too much shaking when the machine runs
Damage to the engine or parts close by
More wear on other parts, which can make your machine work badly and be less safe
You should always check the engine mounts for cracks or bent spots. If you see these, the mount might break soon. When a trained person puts in the mount the right way, your machine works better and lasts longer.
Tip: Go slow and do every step right. This helps you stop big repair bills later.
Ignoring Safety Steps
If you skip safety steps, you can get hurt or break your machine. Some people do not do important safety checks. This can cause leaks, broken parts, or even hurt someone. The table below shows safety steps people miss and what can go wrong:
Safety Step | Associated Risks |
|---|---|
Ignoring Flange Ratings | Leaks, broken flanges, machine stops working |
Neglecting Proper Gasket Selection | Gasket breaks, leaks, machine does not work as well |
Overlooking Bolt Tightening Sequence | Bolts press unevenly, leaks, gaskets get ruined |
Using Damaged or Worn Flanges | Leaks, broken machine, more money spent on fixing |
Incorrect Flange Alignment | Uneven pressure, stress on parts, machine works worse |
Never skip these steps. Each one keeps your motor mount safe and helps stop big problems.
Using Wrong Parts
If you use the wrong parts, you can have big trouble. If a part does not fit or match, you might get shaking or break other parts. For example, if the exhaust elbow is not lined up, the whole system can shake and cost a lot to fix. If one motor mount breaks in a three-point setup, everything can get out of line. This can break your machine and make it unsafe.
Loose nuts on the motor mount brackets also cause trouble. Even if the rubber is still good, loose nuts can make things out of line and wear out fast. Always use the right parts and tighten them well. This helps your mounts last longer and keeps your machine working well.
Note: If you pick good parts from trusted places like YNF Rubber, you can stop these mistakes and keep your machines safe.
