a. Magnetic Starter Magnetic starter is a term that is imposed on the starting of the motor circuits directly using contactors and thermal overload. Figure 2.17 shows an example of a large-capacity magnetic starter for mengasut a 3-phase motors. Medium Figure 2.18 shows the electrical diagram of a magnetic starter control circuit. Figure 2.17 Non-Reversing Starter Magnetic Control Figure 2.18 ...

If the cross-section of a field made up of a cross-sectional arranged symmetrically to the axis line, then the moment of inertia is a number or a reduction of the cross section composed penapang. For example, two squares forming a cross-hatched as shown in the picture, it is the moment of inertia Ix = Ix1 – Ix2. Stackable cross-section of ...
