YEJ Series Electromagnetic Brake Induction Motors are a type of fully enclosed, self-cooling, squirrel-cage DC motor with additional DC electromagnet brakes. They are suitable for all kinds of machinery that requires rapid braking, accurate positioning, reciprocating operation, frequent starting and braking, as the main drive and auxiliary transmission equipment. They feature reliable braking, adjustable braking torque and rotor no axial movement. The rated voltage of the motor is 380V, the rated frequency is 50HZ, the protection grade of the shell is IP44 / IP54, the cooling method is IC411, the reference working system is continuous working system SI, and the insulation grade is F grade. DC electromagnet brakes are mounted on the non-axial end cap of the motor. When the motor is connected to the power supply, the brake also starts to works at the same time. As a result of the electromagnetic force, the electromagnet attracts the armature and compresses the spring; the brake disc is disengaged with the armature and the end cap; the motor begins to rotate. When the power is cut off, the electromagnet of the brake loses electromagnetic attraction, and the spring pushes the armature to press the brake disc. Under the action of friction torque, the motor stops rotating immediately.
