Selection of magnetic powder brake
Magnetic powder brake : The smoothness and constant torque characteristics of the connection are used to achieve buffer start and stop. The hysteresis of the magnetic powder brake's operating surface will occur in the friction mode, but it will not occur here, and the magnetic powder brake will not emit a connection sound. Therefore, the magnetic powder brake operates quite quietly. The magnetic powder brake uses magnetic powder with excellent heat resistance and uses an ideal cooling method, which can be used safely even in the severe continuous sliding operation.
The magnetic powder brake can achieve smooth continuous and driving conditions. Because the static friction coefficient and the dynamic friction coefficient are almost the same, vibration will not occur when fully connected. The selection of the magnetic powder brake is generally based on the required maximum torque to be transmitted, which can be responded to. The acceleration and deceleration of the load, the maximum surface temperature caused by continuous operation is below 90 degrees during operation, and when the value is exceeded, the durability of the magnetic powder brake will be greatly reduced.
Magnetic powder brakes have frequent closing and closing, fast response speed and high frequency, which can reach 40-60 times per minute. Magnetic powder brakes can be widely used in fast working conditions and high-frequency occasions. Magnetic powder brakes are used as overload devices in engines, motors, and electric structures. , Hydraulic components, reducers, and other power machinery for torque measurement load devices, magnetic powder brake power amplification factor is high, magnetic powder brake can use a small exciting current to control a large transmitted power, easy to achieve automatic control.
