Y2EJ series electromagnetic brake motor is a derivative series of Y series motor, so please understand here to understand the parameters of Y series motor. Y2EJ series electromagnetic brake three-phase asynchronous motor is a fully enclosed fan-cooled squirrel cage three-phase asynchronous motor. The series of motors are designed according to IEC standards and have the advantages of large starting torque, compact structure, fast braking, reliable operation, funny energy saving and low noise. In addition, the motor is designed with a manual release structure that can be either electromagnetically braked or manually operated for user commissioning and use.
Y2EJ series electromagnetic brake motor is suitable for power in all kinds of mechanical equipment that requires fast stop, accurate positioning, reciprocating operation, frequent start, and prevention of sliding, such as elevators, reducers, transportation machinery, packaging machinery, food machinery, printing machinery, etc. .
Principle and structure: The retaining disc brake of Y2EJ series electromagnetic brake motor is installed on the non-shaft extension end of the motor. When the motor is connected to the power supply, the brake will start working. Under the action of electromagnetic attraction, the electromagnet attracts the armature and compresses the spring. When the power plate is disconnected from the armature and the end cover, the motor starts to run; when the power is cut off, the brake electromagnet is in the urban lunar calendar, and the spring pushes the armature to press the brake disc. Under the action of the friction force, the motor immediately stops working. The brakes are divided into two types: the energized brake and the de-energized brake. The two brakes work in the same principle, and the braking process is reversed.
Y2EJ series motors can be derived from YDEJ series multi-function brake motor and YVFEJ series variable frequency brake motor. It can also be assembled to YE2 series motor as needed to become Y2EJ2 series electromagnetic brake motor.
Y2EJ motor full name is: Y2EJ series electromagnetic three-phase asynchronous brake motor (referred to as: Y2EJ series electromagnetic brake motor), is a three-phase asynchronous motor with fully enclosed, self-fan cooling, squirrel cage type DC electromagnet brake, is in Y series A DC disc type electromagnetic brake is added between the rear end cover of the motor and the fan, which is a derivative series of the Y series.

Principle and structure
The DC disc brake of the Y2EJ brake motor is mounted on the end cover of the non-shaft 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, the electromagnet attracts the armature and compresses the spring, and the brake disc is The armature and end cover are disengaged and the motor starts to rotate. When the power is cut off, the brake electromagnet loses the electromagnetic attraction, and the spring pushes the armature to press the brake disc. Under the action of the friction torque, the motor immediately stops rotating.

1. The brake has simple structure, few parts, high reliability, easy air gap adjustment and convenient maintenance;
2. The imported excellent bearing is used and has a long service life.
3. The braking frequency is high. The brake pads are attached to the high-quality asbestos board in a special way, which can withstand higher frequency. Low wear rate and no pollution;
4. The brake power supply is directly supplied by the motor. According to different wiring methods, the voltage (AC200～240V) can be taken and rectified into DC power supply (DC80～100V) by the rectifier;
5. Adopt DC DC brake, no electromagnetic sound, low brake noise;
6. Small size, light weight and easy to install. The motor and the brake are integrated into one, the volume is reduced to a small size and the weight is light. The structure is firm and can be installed in a small space; the shape and installation dimensions and performance parameters are the same as the standard Y series motor;
