Principle and Structure

1, stator; 2, rotor; 3, plate; 4, iron; 5, excitation coil; 6, manual release device; 7, brake spring

The DC disc brake of the YEJ brake motor is installed on the end cover of the non-shaft extension end. When the brake motor is connected to the power supply, the brake also works at the same time. Due to the electromagnetic attraction, the electromagnet attracts the armature and compresses the spring, the brake disc is disconnected from the armature and the end cover, and the motor starts to rotate continuously. When the power is cut off, the brake electromagnet loses its electromagnetic attraction force; the spring pushes the armature to press the brake disc. Under the friction torque, the motor stops rotating immediately.

Application

It is suitable for all kinds of machinery that require rapid braking, accurate positioning, reciprocating operation, frequent starting, and braking. It is used as mechanical equipment for the main drive and auxiliary drive. Examples electric valves, rubber chemical machinery, metal processing machine tools, packaging machinery, woodworking machinery, food machinery, chemical machinery, textile machinery, construction machinery, and gear reducers.
