Feature: 1. The motor has strong power, can run at high speed and lasts for a long time, with high temperature resistance and long service life. 2. Different from single-strand winding to generate heat and cause low efficiency, the use of multi‑strand windings has better heat dissipation and avoids skin effect. 3. The magnets on both sides increase the suction power, play an excellent mute effect, and enhance the attractive force of the magnet, thereby improving the lasting quality. 4. The outer winding of the motor is made of copper coil, which has excellent thermal conductivity, ductility and corrosion resistance. 5. The motor is compact, easy to install and use, and is mostly used in vehicles and remote control toys.
