To determine

The four major factors to be considered when installing a motor control in concern with the power system.

Explanation of Solution

The electrical connections that are associated with a motor, machine, and control unit are easy or complex. However, the below-listed factors should be considered while installing a motor and its control.

  • Power source –– Check whether the motor and control unit require a single-phase or three-phase power supply with rated voltage and current.
  • Motor connections –– A motor connection should be made based on the information found on the name plate of a motor. The name plate of a motor contains information such as horsepower, service factor, voltage, and full load current rating.
  • Controller type –– In general, a motor requires simple controller that starts and stops the motor. In addition, a motor may require controllers that vary the speed of the motor at specified time, inching, and jogging.
  • Environment –– The environment should not affect a control unit. The elevated temperature and moisture may affect a control unit.

A program to make the part depicted in Figure 26.A has been created, presented in figure 26.B, but some information still needs to be filled in. Compute the tool locations, depths, and other missing information to present a completed program. (Hint: You may have to look up geometry for the center drill and standard 0.5000 in twist drill to know the required depth to drill).
We consider a laminar flow induced by an impulsively started infinite flat plate. The y-axis is normal to the plate. The x- and z-axes form a plane parallel to the plate. The plate is defined by y = 0. For time t <0, the plate and the flow are at rest. For t≥0, the velocity of the plate is parallel to the 2-coordinate; its value is constant and equal to uw. At infinity, the flow is at rest. The flow induced by the motion of the plate is independent of z. (a) From the continuity equation, show that v=0 everywhere in the flow and the resulting momentum equation is მu Ət Note that this equation has the form of a diffusion equation (the same form as the heat equation). (b) We introduce the new variables T, Y and U such that T=kt, Y=k/2y, U = u where k is an arbitrary constant. In the new system of variables, the solution is U(Y,T). The solution U(Y,T) is expressed by a function of Y and T and the solution u(y, t) is expressed by a function of y and t. Show that the functions are identical.…
