Motor Brush Spring
A motor brush spring, also known as a constant-pressure spring for the carbon brush, maintains steady contact between the brush and the commutator to ensure smooth current flow. This consistent pressure minimizes sparking, noise, and electromagnetic interference, allowing the brush to wear evenly for a longer service life and quieter motor performance.
Teng Yao’s carbon brush springs are available in diverse configurations to meet specific operational needs. Compact types deliver precise tension for household appliances and handheld power tools, while long-stroke designs sustain constant force in continuous-duty motors, pumps, and electric vehicles. Deep-reach models fit recessed brush holders in generators and alternators, and corrosion-resistant variants perform reliably in automotive and outdoor systems exposed to moisture or heat. For dual-brush assemblies, twin-coil springs maintain balanced pressure across wider commutators, enhancing durability and efficiency in industrial and EV drive systems.
