What Are The Characteristics Of The Stand-type Magnetic Powder Brake?

The magnetic powder brake is composed of a rotor, a stator and a yoke with an excitation coil. The three parts are relatively concentrically assembled to form a relatively rotatable whole body. The annular space (working cavity) between the rotor and the stator is filled with high magnetic permeability. Alloy magnetic powder.

When the excitation coil has no current, the magnetic powder in the working chamber is loose. Under the action of the centrifugal force generated by the rotor, the magnetic powder clutch manufacturer uniformly smashes the magnetic powder on the inner wall of the rotor. The rotor and the stator have no force interaction, and the magnetic powder brake is in an idle state without torque output.

When the excitation current remains unchanged, its torque is not affected by the rotational speed of the rotor, that is, there is no difference between the static friction torque and the dynamic friction torque, so that the torque can be stably achieved. This feature is applied to the power test. The user can accurately control the torque by adjusting the excitation current to effectively control the load resistance.

The rated magnetic powder brake is rated at DC24V and can be used at 5r/min. It helps to increase the heat capacity by dissipating compressed air into the open space. In order to improve the cooling effect, an axial flow fan can also be arranged at one end of the driving body; note that the cooling compressed air must pass through the air filter to ensure no oil, no water, and dry air.

There is a small open space between the magnetic coil of the base magnetic powder brake clutch and the transmission unit, so a large magnetic power is required. The size of the magnetic powder brake manufacturer coil and the fuselage is also relatively increased, but the flywheel moment of the input shaft required by the two is correspondingly reduced. A smooth continuous and driven state can be achieved. Since the static collision coefficient and the dynamic collision coefficient are almost the same, there is no oscillation when the connection is completely connected, and the load can be accelerated or decelerated.

Seat type magnetic powder brake features: able to get stable torque. Easy to handle a wide range of controls. Can achieve continuous sliding work. No sounds. The heat capacity is large. Thanks to the use of magnetic powder with excellent heat resistance and the use of aspirational cooling method, even if it is too strict continuous sliding work, it can be used with peace of mind. The slip phenomenon of the action surface of the automatic tension controller occurs in a conflict mode, but it is not presented here, and no connection sound is emitted, so the work is quite quiet.
