Introduction
It is made of international imported silicon steel materials, bearings and imported German technology. The surface is coated with rotor rubber to prevent the oxidation of silicon steel to reduce the surface burrs after grinding. Compared with the industry, the torque of the motor is larger, the output is more stable, the noise is lower, and the life is longer.

The motor coil is made of pure copper enameled wire and advanced winding and over-wire technology. The copper wire is evenly distributed, the motor temperature rises lower, and the deformation and noise problems will not occur for a long time.
