Which is better, brushless toothless or brushless geared hub motor?

1. The brushless and toothless motor is more convenient and durable, and the toothless one has no gear transmission, so there is no need to replace the gear oil.
2. In-wheel motor technology is also called in-wheel motor technology. Its biggest feature is that it integrates the power device, transmission device and braking device into the wheel hub, which greatly simplifies the mechanical part of the electric vehicle.
3. Motor (English: Electric machinery, commonly known as "motor") refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. In the circuit, it is represented by the letter M (the old standard is D). Its main function is to generate driving torque as a power source for electrical appliances or various machinery. The generator is represented by the letter G in the circuit. Its main function is to convert mechanical energy into electrical energy. At present, the most commonly used is to use heat energy, water energy, etc. to drive the rotor of the generator to generate electricity.
