The voltage of electro-hydraulic block brake is generally 380V in China, and the explosion-proof type is 380-660-1140V
Brake working conditions
The relative humidity of the surrounding air is not more than 85% (20±5℃)
In the surrounding medium, there is no gas or dust that can corrode metals and damage insulation.
Class B insulation is used around the brake, and the voltage fluctuation does not exceed +5% and -15% of the rated voltage. Its working mode is the installation control requirement of continuous work. The specific process and requirements for installing the inverter on the brake.
Basic requirements when selecting a matching inverter for a motor with a brake. A motor with a brake must have a regenerative braking signal processing unit inside or an additional regenerative braking signal processing unit as an option.
At the same time, in order to maintain the motor positioning, emergency stop and stop, a motor with a mechanical brake should generally be used.
The connection requirements of the frequency conversion speed regulation system to the brake power supply:
The brake power supply must be connected to the input end of the inverter, because the output voltage of the inverter is low voltage at low speed, so the suction of the electromagnet will be weakened, and the brake will be released, which is not allowed.
Therefore, the voltage of the brake cannot be the same as that of the motor.
When installing, ensure the matching accuracy between the drive shaft and the brake.
The brake must be cleaned before installation, and there must be no oil and dust on the friction surface and inside the brake. A series of special devices that can forcefully reduce the speed of a car. The braking system is mainly composed of four parts: energy supply device, control device, transmission device and brake. The main function of the braking system is to slow down or even stop the driving car, keep the speed of the downhill car stable, and keep the stopped car stationary. The braking system is a must on every kind of vehicle. If there is no braking system , That kind of scene is unimaginable. In the brake system, the brake is also very important. Generally speaking, the front wheel brake has a greater effect and exceeds the contribution of the rear wheel brake. The front brake is generally divided into two types: drum type and disc type.
