As the power core of micro gear pumps, motors directly determine the operating efficiency and service life of the pump body. There are significant differences in core performance between the mainstream brushed motors on the market and the brushless motors adopted by J-Tron, which become key factors affecting the performance of liquid control component.
J-Tron Brushless Motor
The core differences between the Brushed Motor and Brushless Motor in four key aspects, with obvious gaps in performance and safety:
◇◇◇Structure & Commutation Mode: Brushed motors rely on physical carbon brushes and commutators for current commutation. During operation, the carbon brushes slide continuously against the commutator, which is the root cause of many performance and safety issues. Brushless motors adopt electronic commutation technology, eliminating carbon brushes and commutators entirely, and rely on electronic control modules to realize current direction switching, with a simpler and more reliable structure.

◇◇◇Service Life: The carbon brushes of brushed motors are vulnerable parts. Under long-term high-speed friction, they are easily worn out, and the service life is usually only 1000-3000 hours, requiring frequent replacement and increasing maintenance costs. Brushless motors have no wearable components like carbon brushes, and their service life can reach more than 20,000-30,000 hours, realizing long-term maintenance-free operation.
◇◇◇Operating Performance: The friction between carbon brushes and commutators in brushed motors leads to low energy conversion efficiency (generally ≤70%), high operating noise (usually above 60dB), and unstable speed due to uneven brush wear. Brushless motors have no friction loss, with an efficiency of over 90%, running noise below 40dB (close to silent), and stable speed output, ensuring precise flow control of micro gear pump.
◇◇◇Safety Performance: Brushed motors have significant safety hazards. The continuous friction between carbon brushes and commutators will generate sparks and carbon dust. The accumulated carbon dust is flammable, and sparks may ignite dust or surrounding flammable materials in extreme cases, posing a fire risk. In addition, carbon brush wear may cause poor contact and abnormal heating, further increasing safety risks. Brushless motors avoid spark generation due to no carbon brush friction, and there is no risk of carbon dust accumulation, so they have higher safety and are suitable for scenarios with strict safety requirements.
J-Tron micro gear pumps are fully equipped with brushless motors, which adapt to high-precision scenarios such as inkjet printing, medical care, and other fluid control and transfer industries by virtue of the above advantages, realizing precise flow control and long-term stable operation.
