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.
Speed for constant torque under 1500 r/min, More than 1500 r/min for constant power.
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.
