Feature: 1. HIGH EFFICIENCY: High purity copper windings maximize efficiency. Equipped with high strength magnets to reduce friction and noise. External carbon brushes can be replaced to ensure that it can work stably for a long time. 2. LONG SERVICE LIFE: External carbon brushes can be replaced at any time to ensure that they can be used for a long time, providing users with a long lasting and reliable operating experience. 3. ACCURATE DESIGN: It is accurately designed for maximum energy conversion. The accurate rotor ensures smooth operation, improves reliability and maximum speed for superior performance. 4. HIGH PERFORMANCE: Brushed motor has high torsion output. The circuit design is delicate and can effectively resist interference. Bi directional bearing strengthens the magnetic force and reduces heat generation for more power. 5. SMOOTH STARTING: Reduces motor speed when the torsion needs to exceed the RPM, providing smooth vehicle starting and preventing the car from shaking and stalling during startup.
