Electromagnetic brake asynchronous motor is a combination of electromagnetic brake and asynchronous motor motor, it not only has the asynchronous motor simple structure, easy manufacturing, reliable operation, easy maintenance and durable advantages, but also has the electromagnetic brake fast braking, easy control and other characteristics. Electromagnetic brake asynchronous motor is widely used in a variety of applications requiring fast braking and precise control, such as machine tools, elevators, cranes and electric hoists.
The working principle of electromagnetic brake asynchronous motor can be divided into two parts: the working principle of asynchronous motor and the working principle of electromagnetic brake.
Initially, the working principle of asynchronous motor
The working principle of asynchronous motor is based on the principle of electromagnetic induction. When a three-phase alternating current passes through the stator winding, a rotating magnetic field is generated. This rotating magnetic field induces an electromotive force in the rotor conductor, which, since the rotor conductor is closed, generates an electric current. The rotor current interacts with the rotating magnetic field to produce an electromagnetic force in the opposite direction of the rotating magnetic field, which causes the rotor to rotate with the rotating magnetic field, but because the rotor speed is always less than the rotating magnetic field speed, so the name "asynchronous" is generated.
Second, the working principle of the electromagnetic brake
The working principle of the electromagnetic brake is based on the principle of electromagnetic suction. When energized through the brake winding, a magnetic field is generated, which attracts the armature in the brake and makes it move, thus achieving braking. When the power is off, the spring in the brake pulls the armature back, releasing the brake.
Third, the working principle of electromagnetic brake asynchronous motor
The working principle of the electromagnetic brake asynchronous motor is to combine the asynchronous motor and the electromagnetic brake. When the motor is energized, the rotating magnetic field will make the rotor rotate, and the winding of the electromagnetic brake will also be energized, so that the brake is released and the Electromagnetic brake asynchronous motor runs normally. When the power is off, the rotating magnetic field disappears, the rotor slows down, and the winding of the electromagnetic brake is powered off, and the spring in the brake pulls the armature back to realize fast braking.
The advantage of electromagnetic brake asynchronous motor is that it can achieve both fast braking and precise control. In the need for frequent starting and braking occasions, such as machine tools and elevators, such motors can greatly improve work efficiency and safety. At the same time, because of the simple structure of electromagnetic brake asynchronous motor, manufacturing and maintenance are relatively easy, so in a variety of industrial and civil occasions have a wide range of applications. From light industrial machinery, automated production lines, lifting and transportation equipment to elevators, vehicle braking systems are involved. Especially in situations where fast and precise braking is required, such as emergency braking of elevators, precise positioning on automated production lines, and rapid stopping of stage machinery, electromagnetic brake asynchronous motors show unique advantages.
In general, electromagnetic brake asynchronous motor is a combination of asynchronous motor and electromagnetic brake motor, it has the dual advantages of asynchronous motor and electromagnetic brake, widely used in a variety of need for fast braking and precise control occasions.
