Abstract
The invention relates to a high-temperature resistant and energy-saving electromagnetic brake, which comprises a magnetic yoke body (1), an electromagnetic coil (2), an armature (3), an armature reset spring (8), a static friction disc (4) and a dynamic friction disc (5). An internal water chamber (100), an external water chamber (101) and a communicating pipe (104) are arranged inside the magnetic yoke body (1), and a water inlet pipe (102) and a water outlet pipe (103) are arranged on the magnetic yoke body (1). The water inlet pipe (102) and the water outlet pipe (103) are respectively communicated with the internal water chamber (100) and the external water chamber (101) which are communicated by the connecting pipe (104). The electromagnetic brake adopts a circulating water cooling mode to dissipate heat for friction discs and the electromagnetic coil, which has good heat dissipation effect and reduces the energy consumption of the electromagnetic coil. In addition, the water flow direction of the circulating water, which first enters the internal water chamber of the magnetic yoke body and then flows to the external water chamber, can not only increase the heat dissipation effect, but also effectively prevent the damage to the electromagnetic coil caused by heat radiation at high temperature.
