Flange Faces

As you start to consider purchasing flanges or gaskets, you’ll see a variety of terms used that you may not have come across before. Flange faces are the surface area that will receive the gasket, allowing them to come together to create a seal when put under...

Octagonal Ring Type Joints

A ring-type joint is a metallic ring that is machined to sit between two mating surfaces, where it will be compressed to provide a high-quality and reliable seal. Ring-type joints are vital components in various applications across multiple industry sectors,...

Blind Flange vs Blank Flange

Small pieces of mechanical equipment flanges continually play a vital role across numerous industries and applications. In essence, we use flanges to connect pipes to each other, with flanges also found in valves and specific application fittings too. Due to the...

Types of Flanges

Businesses in a variety of industries rely on flanges to join pipes or components together or to keep equipment secured to a surface. When it comes to choosing the best types of flange for your processes, you’ll want to take the time to research the different options...

Threaded Flange

Threaded flanges are probably the most recognisable of all flanges due to their screw thread design that is used to connect it to the pipe. Threaded flanges, also known as screwed flanges (for obvious reasons), require a male and female thread to create a connection...

Slip On Flange

A slip-on flange can also be known as a hubbed flange, which, as the name suggests, has a hub with a very low profile. Why is this important? Because this type of ring type joint gasket has an internal diameter larger than the connecting pipe, allowing you to slide it...

Weld Neck Flange

Also known as tapered hub flanges or high hub flanges, weld neck flanges are a specific type of gasket with a protruding ridge and long neck used to connect pipework and provide you with a high-quality seal. Weld neck flanges, in particular, are a popular choice when...

Nitrile vs Viton® – What is the Difference?

As you start to make a decision about what type of O-rings to purchase for your business, you might wonder what material is the most suitable for your unique needs. Every business operation has different requirements for their O-rings, such as the temperature,...

Aflas vs Viton

How to Choose the Right Seal for Electric Motors

How to Choose the Right Seal for Electric MotorsWhen choosing a seal for your electric motors, there are many options on the market. Finding the right electric motor shaft seal is critical to ensure your customers are happy and that your vehicles fit their needs. Keep reading to discover how to choose the right seal for your electric motors, so that you can offer consumers the best product possible with minimal issues in the future.

The Sealing Requirements for Electric Motors

When compared to the typical combustion engine, you’ll find that electric motors have very different sealing requirements. Thanks to the new technology that’s on offer today, you’ll find there are various applications to consider when choosing the right seal for your vehicle. Of course, there are many advantages to using an electric motor over internal combustion engines, including the reduction in moving parts and minimal friction points. You won’t have to worry about internal lubrication, thanks to the lack of pressurised and circulating oil.

In general, you need to think about the dry running capability when it comes to your electric motor needs. The electric motor shaft seal needs to be able to run in an outdoors or dirty environment, so it will need to protect the vehicle from dust and debris. You also need to consider the fact that water and other lubricants from the systems can get into the motor, which can destroy the operation of the motor. Some production motors can run at up to 18,000 rpm, which is more than three times the speed of typical gas engines. You’ll also find that some smaller motors can go even faster, which is a testament to how far this technology has come in recent years.

When it comes to choosing the right motor seal, you need to ensure it will be able to survive at a high running speed and offer a good lifespan. This will minimise the chance of issues for your customers, which can often occur simply due to sealing faults. All the parts that go around and into your electric motor seal make a huge difference to the quality of the final product, which is why choosing the right gasket or seal is critical for your business.

Low Friction Electric Motor Seals

Another consideration for the sealed motor is that you need to ensure it can run at low friction. Many motor seals create a drag, which is never good for the efficiency of the motor. However, you need to ensure you can minimise the frictional loss to the best of your ability. When you have an electric car or another battery-powered vehicle, you’ll find that efficiency is reduced when there is friction created with the seal. When the motor has to work harder, it will use more energy to push the vehicle forward, as more of the battery is also required.

When discussing seals and electric cars, you’ll find that the biggest issue for consumers today is the length of charge for the battery. With competition increasing in this field, it’s critical that manufacturers strive to offer the best product possible to consumers. When the range can be extended, it’s a huge selling point for potential customers. By choosing the right motor seal, you can reduce the friction, making for a much more effective driving experience for anyone who purchases from your company. By focusing on reducing inefficiency losses, you can ensure that the range is at the highest possible for the type of product you are offering.

In the automotive industry, you’ll find that motor seals for low friction are required within automation and precision robotics. Due to the limited space on offer, we often find that the motor size is limited in this field. A good example of this would be a robotic arm, which needs to be lightweight and physically small. You’ll need to find smooth and consistent motors that offer dynamic motion, which can support the fast and precise movements these types of motors need. We generally recommend avoiding rubber and elastomeric seals for this type of motor, as they can increase the jerkiness of the movement, which is something you should be looking to avoid with any type of motor.

There’s a lot to consider when it comes to choosing the right seal for your electric motors. We highly recommend taking the time to find the right option for your vehicles or applications, so that you minimise the issues involved with this type of seal. Our team will be happy to advise you about the best option for your unique needs and will support you during your work in the future.
