The perfect combination of rubber and rotor makes the internal structure more stable, and also reduces the vibration and noise when the engine runs. The motor runs more quietly, with a high torque of 425oz in. The coil uses pure copper enamelled wire to ensure that long-term operation will not lead to excessive engine temperature. The rotor surface is coated with high-quality epoxy resin adhesive to isolate the adsorbed burrs on the rotor surface, more stable magnetic field and longer service life of motor.
