    Choosing a Shaft Coupling for Motor-Gear-Wheel Connection

    It depends on your budget. I'm not sure what you mean by "below shaft". Do you mean "bellows" coupling? So named because they have a bellow shape. If cost is not an issue, a bellows coupling will be much stiffer than a helical coupling. The drawback is it is not as flexible. If you don't...

    Piezo Actuator Power Consumption

    Hi all, Mechanical engineer needing some electrical help. So electrically piezo actuators are modeled as capacitors. Power(P) = C*U*dU/dt, where U equals voltage. I'm seeing several sites like here: http://www.piezo.ws/piezoelectric_actuator_tutorial/Piezo_Design_part3.php They...
