Three-phase AC brake motors (three-phase asynchronous motors) are widely used and have the advantages of light weight, low noise and good effect. According to its principles, there are mainly the following types of brakes.
1. Holding brake: It is also a relatively common braking method, which is mainly used in hoisting machinery and other industries, such as winches and electric machines. The advantage is that the positioning is accurate, which can prevent the motor from falling down at noon after a sudden power failure during the work process, such as elevators, cranes, etc. The disadvantages are serious wear, short life, large vibration, and large volume.
2. Energy consumption braking: a braking mode that uses the energy of the rotor to cut the magnetic flux to generate braking torque. The essence is to consume the kinetic energy of the rotor in the resistance of the circuit. The advantage is that the braking force is strong and stable, and the positioning is accurate. The disadvantage is that it requires direct current, and the braking force is small at low speeds and the cost is high.
3. Reverse connection braking: that is, reverse connection of the positive and negative poles of the motor to change the direction of the current and thus the direction of the torque. The advantages are strong braking force, rapid braking, low cost, simple and convenient. The shortcomings are also obvious, the resulting impact is large, it is easy to cause damage to the transmission parts, and the positioning accuracy is poor.
The AC brake motor is simple to operate and low in cost, and is widely used in the market. If you have any needs, you are welcome to call our company for consultation or on-site inspection.
