    Combined electromagnet and permanent magnet, c shaped with permanent magnets in the air gap

    The eddy currents are produced only during high angular velocity, and the actuator bar brings the magnets into proximity with the rotor. There is no static holding force.

    Combined electromagnet and permanent magnet, c shaped with permanent magnets in the air gap

    HI Magmike Thanks: I am looking at the Adamsmagnetic web site and have selected magnets based on the ability to transfer energy, which is I assume is a function of not only field strength, but also the interaction of the magnet and the material it is inducing the current into. Some sort of...

    Combined electromagnet and permanent magnet, c shaped with permanent magnets in the air gap

    I am working on an induction disc braking device that typically uses permanent magnets to create eddy currents and generate heat and drag, however, I desire to use a combination of electromagnet and permanent magnet for control purposes. The magnets are mechanically positioned to create a base...

    Ammonia removal concept for review and comment

    This wastewater stream is intermitent, and we are in a very cold climate. The waste characteristics can change rapidly. We may use aerobic treatment followed by anerobic treatment but these plants require full time operation, and an upset causes us great problems, as we have no place to store...

    Ammonia removal concept for review and comment

    Wastewater stream is a sludge dewatering filtrate. Cost of chlorine is high but more favorable than buying chemicals, and over time will save money. Looking at several different chlorine generators. Scaling can be controlled by washing periodiclly with HCL solution

    Ammonia removal concept for review and comment

    I have a 50,000 gpd wastewater stream with parameters as follows: 15 degrees C 100 ppm ammonia, PH=7.2, TSS=nil, BOD5=200, COD 300 , flow rate, nitrate=0, nitrite=0. Need to get rid of the ammonia, and discharge at 20 ppm ammonia or less. Plan on generating chlorine on-site using...

    Anyone having problems with disclipline overlap issues

    I am a practicing structural engineer. Many of our projects are small building projects. Architects in our community are saying that ANY structure for human occupancy needs an Architect as the project leader. We in the engineeing community feel the client can decide what range of services they...
