Overview

Whether you’re designing or supplying a wiper motor, a starter motor or an electric pump motor, your components need protection from environmental challenges — dirt, dust, water and automotive fluids - that can create performance problems for motors.

Microporous ePTFE vents from Gore protect automotive components from the elements while providing high airflow. Tier-1 global suppliers rely upon our vents to:

  • block dirt and dust particulates from infiltrating housings and reducing efficiency
  • effectively reduce condensation and prevent ingress of water, rain and harsh automotive fluids
  • rapidly equalize pressure differentials, reducing stress and wear and extending service life

No two applications are exactly alike. Because of our expertise in ePTFE, we can customize our solutions to meet customers’ applications, designs and requirements. By collaborating closely with suppliers, we can engineer the right venting solutions that perform reliably in even the harshest conditions.

Product Comparison

Gore offers qualified vents for motor applications. We extensively test and evaluate each vent to ensure it performs consistently and reliably.

These are some of our most popular vents for motor applications. Contact us to discuss your application and we’ll evaluate the requirements and match them to a standard or custom venting product.

Applications

Wiper motors, electronic pump motors and starter motors each have specialized application requirements that must be met to ensure performance and reliability. Common challenges include extreme temperatures and pressure fluctuations, which can impact operations.

For each set of challenges, GORE Automotive Vents for Motors reliably meet customers’ requirements and performance needs.

Wiper Motor
Wiper Motor

Wiper motors are critical to driver safety, yet their durability can be threatened by anything from extreme weather to owner-applied cleaning agents or high-pressure steam jets. In an increasingly cost-sensitive environment, OEMs require more effective venting to protect and extend the service life of wiper motors, reducing warranty claims. Gore has a portfolio of venting solutions engineered to preserve peak wiper motor performance, more cost-effectively: Our membrane cut-part vents (AVS 25, 26, 28, 29 and 39) and our three-layer cut part vents (AVS 47, 48, 49, 50, 51 and 52).

 

Electronic Pump Motor
Electronic Pump Motor

Emission and fuel-consumption considerations are driving the transition from belt-driven mechanical pumps to electronic pumps. However, sensitive electronics require more protection from under-hood hazards like extreme temperature differentials and exposure to automotive fluids or high-pressure steam spray. High-airflow vents are engineered to manage rapid temperature and pressure changes while effectively reducing ingress from water, fluids, and other contaminants. With proven performance, our vents protect electronic pump motors more reliably for fewer warranty claims.

 

Starter Motor
Starter Motor

Starter reliability is always crucial, especially with the introduction of the new "start⁄stop" systems, which cycle much more often than older designs. To perform reliably time after time, these systems require advanced protection - from large temperature differentials as well as from automotive fluids, dirt, and other particulates. Our durable vents provide long-lasting protection for starter motors exposed to harsh under-hood conditions and road-debris hazards.
