YEJ electromagnetic brake motor product description
The full name of YEJ motor is: YEJ series electromagnetic three-phase asynchronous brake motor (referred to as: YEJ series electromagnetic brake motor), is a fully enclosed, self-fan cooling, squirrel cage type additional DC electromagnet brake three-phase asynchronous motor, is in the Y series A DC disc electromagnetic brake is added between the rear end cover of the motor and the fan, which is a derivative of the Y series.
Application range of YEJ electromagnetic brake motor
YEJ series electromagnetic brake three-phase asynchronous motors are widely used in all kinds of machinery requiring fast braking, accurate positioning, reciprocating operation, frequent starting and braking, as mechanical equipment for main transmission and auxiliary transmission. For example: electric valves, rubber chemical machinery, metal processing machine tools, packaging machinery, food machinery, chemical machinery, textile machinery, construction machinery and gear reducers, etc. And used in various occasions that require quick stop and accurate positioning, such as the head of crane transportation machinery used for lifting and walking machinery, various metal cutting machine tools, printing machines, forging machines, cement mixers, woodworking machinery, paper machinery , Rubber and plastic machinery and textile machinery, etc., are also widely used in cultural and entertainment venues.
Characteristics of YEJ electromagnetic brake motor
Reliable braking, adjustable braking torque, no axial movement of the rotor, easy to use.
YEJ electromagnetic brake motor standard form
The motor meets the requirements of JB/T6428-92 <YEJ series (IP44) electromagnetic brake three-phase asynchronous motor technical conditions (frame number 80-225)>.
The rated voltage of the motor is 380V, the rated frequency is 50HZ, the protection grade of the housing is IP44, the brake is IP23, the cooling method is IC411, the standard working system is the continuous working system SI, and the insulation class is B.
Principle structure of YEJ electromagnetic brake motor

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