           CW series eddy current brake
           Hits:14601 AddTime:2021/9/10 10:00:56

          Eddy current brake, as a kind of load, mainly used to measure the dynamic mechanical properties of test equipment, it and other control measuring instrument can be eddy current dynamometer.Can be used for internal combustion engine, motor, gas turbine, automobile and machinery components performance test, compared with other dynamometer device, the CW series dynamometer device has higher reliability, stability, and practical.
          Main features:
          1. Simple structure, stable operation, low price, convenient in operation and maintenance.
          2. Use water cooling, low noise, small vibration.
          3. Enter the wide speed range.
          4. All previous control power is small, the single-phase dc power supply.
          5. With measurement and control system, which can realize automation control.
          6. Used as a brake, a braking force is large, the advantages of good and stable performance.
          Working principle:
          1. The base to structure of the CW series eddy current brake (see below)

          The CW type eddy current brake (with groove wheel), by the rotor stator (including around the armature, excitation coil, end cover, bearing cover), frame composition.
          Eddy current ring around the armature body (with) have the same cooling waterway, set in the excitation coil is installed before the two armature body, after the cooling water from inlet to the armature into vortex ring cooling water tank, lower body but buckle from the upper half of the armature body flow in and out of the gate, through the outlet flow out.
          2. The working principle of the CW series eddy current brake
          When the rotor with coaxial excitation coil assembly to pass a dc TV, its produce magnetic menstruation armature, eddy current ring, air gap and the rotor to form closed magnetic circuit.Due to the rotor outer surface is made into uniform distribution of teeth and slots, so in the air gap and vortex ring surface density can be found in the magnetic field.Therefore, when the rotor is dragging rotates, the eddy current ring as a point on the surface of the magnetic field to produce alternating changes, the induction, the magnetic field which is formed by the "vortexing" and interact with the original air-gap magnetic field, creates a braking torque on the rotor.Engine output power is converted into vortex ring "vortexing" to produce the equivalent of heat, the heat by the eddy current ring into the continuous cooling water in cooling water tank.

          6. Usage, transportation and storage of electric eddy current brake

          6.1 The environment temperature of electric eddy current brake is 0 — +40, the relative humidity is not more than 85%. Install the device below 1000 meters above sea level.

          6.2 Electric eddy current brake should be installed on a solid foundation without any shock vibration and the surroundings shall be free of acid, alkali, salt and other harmful substances.

          6.3 Transportation and storage temperature: - 30  ~ + 50  (hydrops in the cooling system shall be emptied); Transportation can be carried out in the case of packing. The speed shall keep less than 30+5 km/h on tertiary highway. Both railway and waterway are permitted.

          6.4 Because the power generated by the tested machine is absorbed by electric eddy current brake, CW series electric eddy current brake shall be equipped with water in case of operation. Or the electric eddy current brake would be burnt out.

          With the exception of a few heat dispersed through the shell, most heat generated by the power absorption is concentrated on the eddy current component. Therefore, as shown in Figure 1, there are several cooling water flow channels on the back of vortex ring. The external cooling water passes the flow channel and makes heat exchange with magnetic ring. The heated water runs away through pipes.

          Cooling water is an important guarantee to ensure the normal operation of electric eddy current brake. The pipe with special dimension shall be installed at the inlet and outlet of eddy current brake. To inspect the leakage of water supply system and the prescribed value of water flow by means of water testing.

          The cooling tap water and water in circulating pool can be used as the cooling water. When using circulating pool, the heat dissipation of cooling water shall be taken into consideration with the inlet temperature of≤25. The cooling water shall be clean tap water without salt, alkali and other corrosive substances, which can prevent the rapid formation of incrustation. Users can identify and judge the local water quality and take measures to prevent incrustation formation, especially in hard water areas. Or the channel of eddy current brake would be blocked quickly. And also, users can add anti-rust agent and anti-fouling additives to prolong the service life of eddy current brake.
