3 Reasons Why You Should Use Oil-free Motors in the Food Industry

In food production, every component in your production line must meet the highest sanitary standards—including your motors. Traditional oil-lubricated motors come with hidden risks: they can leak, require extensive maintenance, and waste energy. Oil-free motors eliminate these concerns, offering a safer, more efficient, and more reliable alternative.

Yet, many machine builders hesitate to make the switch. Why? Because they’re unaware of the risks of oil-lubricated motors or assume that food-grade lubricants solve the problem. Let’s break down why oil-free drum motors are the smarter choice.

1) Eliminate the Risk of Oil Contamination

Oil leaks in drum motors are more common than you might think. Even major suppliers acknowledge that leakage can happen during normal operation. The fact that H1 food-grade lubricants exist at all proves that some level of contamination is expected. The problem is that these leaks often go unnoticed because:

  • They occur gradually as microleaks, making them difficult to detect.
  • There is no routine testing for excess lubricants in food products.

This creates a false sense of security. While regulations limit food-grade lubricant contamination to 10 ppm, there is little oversight, meaning leaks can go undetected—until it’s too late.


Food-grade lubricants are not designed for consumption, and their presence in food should be minimized. They are a mixture of chemicals, and some studies suggest they can even serve as a breeding ground for bacteria like Listeria. The assumption that using food-grade lubricants makes oil leaks “safe” is a misconception.

Oil-free drum motors eliminate this risk entirely. By removing oil from the equation, you prevent contamination at the source rather than trying to mitigate its effects later.

2) Reduce Maintenance and Downtime

Oil-lubricated motors require ongoing maintenance, including:

  • Regular oil changes.
  • Leak inspections and repairs.
  • Managing compliance with food safety regulations related to lubricants.

This results in unplanned downtime and higher operational costs.

Oil-free drum motors, on the other hand, eliminate the need for oil-related maintenance. With fewer components subject to wear and tear, they last longer and keep production running smoothly.

3) Improve energy-efficiency

Our oil-free drum motors weren’t just designed to eliminate oil—they were built to be more energy-efficient. Here’s how:

  • Synchronous Motor Technology: Unlike traditional motors, our drum motors use synchronous technology, which inherently reduces energy loss.
  • Stronger Mechanical Design: Because we eliminated oil, we reinforced the motor’s internal structure to ensure durability and efficiency.
  • Lower Energy Consumption: In tests comparing our oil-free synchronous drum motors to conventional gear motors, we found up to a 36% reduction in annual energy consumption.

Addressing Common Concerns:

“Why Haven’t I Heard About Oil-Free Drum Motors?”

Oil-free drum motors are still gaining awareness in the industry. Even the latest EHEDG guidelines for hygienic conveyors do not yet mention them, leaving many machine builders unaware of their advantages. However, leading food processing companies are already adopting this technology for its superior hygiene and performance.

“What If the New Technology Fails?”
Many OEMs and purchasing teams hesitate to move away from established brands because they want to stick with what they are familiar with. But sticking with the status quo means continuing to accept known risks, rather than choosing a safer alternative. 


“Are Oil-Free Motors Harder to Maintain?”
No. In fact, they require significantly less maintenance because they eliminate the need for oil changes, inspections, and leak management. Less maintenance means fewer production stoppages and lower costs.
