European Manufacturer Develops Custom Piston Air Pump with Our Compact DC Gearbox Motors

A European manufacturer recently reached out to us for assistance in developing a custom piston air pump. They needed a compact DC gearbox motor that meets the following specifications:

  • Nominal Voltage: 12V preferred
  • Rated Torque:
  • On Load Speed: 120RPM

Application Requirements

In their application, the motor only needs to operate in one direction. The motor will be used for a few minutes at a time, with a maximum of 300 minutes per day in the worst-case scenario. To ensure a long life cycle of 10 years, the manufacturer prefers brushless DC gearbox motors. Since they have their own electronic drive to control direction and speed via PWM, the brushless motors should be built with U, V, W 3 wires, and sensors.

Our Solution

After a thorough evaluation by our engineering team, we determined that the load in their air pumps varies with air pressure. This means the loading torque fluctuates, rather than remaining at the rated To meet these requirements, we recommended our 42mm diameter brushless planetary gearbox motor, model HT-BL-POG42. This motor is designed to handle varying loads and maintain performance.

Testing and Results

The customer conducted lifespan tests for almost a year after receiving customized samples. The samples not only passed the functional tests but also met the lifetime goal.


Our HT-BL-POG42 brushless planetary gearbox motor proved to be the ideal solution for the European manufacturer’s custom piston air pump. If you have similar needs or require a reliable, long-lasting motor for your application, please contact us to discuss how our products can meet your requirements.
