A brief analysis of the braking method and wiring method of Motorcycle Brake Pads
The density of the Brake Accessories, that is, the mass per unit volume (g/Cm³). For Brake Accessories, the density can basically indicate whether the ratio between the constituent materials is reasonable. The density of Brake Accessories is generally 1.6~2.3, of which: the density of asbestos Brake Accessories is 1.8~2.1, and the density of steel fiber Brake Accessories is 2.4~ 2.8.

Density is generally determined by hydrostatic weighing.
Cut three cuboid samples with a height of 15mm and a width of 10mm from the finished Brake Accessories, and then immerse them in liquid (distilled water) by dipping method, and weigh them in water. Density precision.
This is a very common way to mount resistive wheels on motorcycles and hold the brakes, when the electromagnet loses power, the spring pulls on the brake pads, doing the mechanical resistive locking job.
Wiring method: keep the power supply of the brake electromagnet connected to the power supply of the motorcycle, and use phase voltage or line voltage coils.
Generative energy-consuming emergency braking is accomplished immediately while the motor is de-energized and ceases operation, delivering limited time and rated DC current on any two-stage motor.
Motorcycle Brake Pads wiring method: The DC power comes from the self-distributor, autotransformer and silicon rectifier, which is linked with the start and stop of the motorcycle, and is completed by a time relay and a contactor.
After the motor stops energizing and stops rotating, a time-limited current, a limiting resistor, and two-phase reverse rotation power are supplied to the motor immediately, and the reverse rotation torque is used to complete braking. This method is suitable for places where emergency braking is required.
Wiring method: link the start and stop of the motor, and connect the corresponding high output resistance in series through the time relay, connector and three-phase power supply.
