The Importance Of Magnetic Powder Brakes To Convey Torque

When the magnetic powder brake is connected to the prime mover or load, it is recommended to use a flexible coupling to avoid excessive radial force on the shaft end. When driving with a pulley or gear, use a bracket or other appropriate mechanism to isolate it from the magnetic powder brake. The newly installed magnetic powder brake should be domesticated before the magnetic powder is uniform and stable. If there is no domestication condition at the installation site, it is recommended not to put it into operation immediately after installation. The desulfurization damper should be under the conditions that can be achieved. Test run at the appropriate time, and then put it into operation.

The selection of the magnetic powder brake is generally selected on the basis of the required maximum torque, and at the same time, it is ensured that the actual slip power is less than the allowable slip power of the magnetic powder clutch and brake. When the magnetic powder brake has a certain heat dissipation condition, the slip power is a certain value, so the actual working torque and the rotational speed can compensate each other. When the slip speed is increased, the allowable torque will decrease accordingly, but the maximum speed cannot be higher than Its licensed speed.

The magnetic powder brake has a large heat capacity. Since the magnetic powder brake uses a magnetic powder with excellent heat resistance and an ideal cooling method, it can be used with peace of mind even in an extremely severe continuous sliding operation. The magnetic powder brake has a characteristic that the excitation current and the transmission torque are substantially linear. The magnetic powder brake is based on the electromagnetic principle and uses magnetic powder to transmit torque.
