A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the power and signal connections between the devices.
A wiring diagram usually gives information about the relative position and arrangement of devices and terminals on the devices, to help in building or servicing the device. This is unlike a schematic diagram, where the arrangement of the components' interconnections on the diagram usually does not correspond to the components' physical locations in the finished device. A pictorial diagram would show more detail of the physical appearance, whereas a wiring diagram uses a more symbolic notation to emphasize interconnections over physical appearance.
A wiring diagram is often used to troubleshoot problems and to make sure that all the connections have been made and that everything is present.
Architectural wiring diagrams show the approximate locations and interconnections of receptacles, lighting, and permanent electrical services in a building. Interconnecting wire routes may be shown approximately, where particular receptacles or fixtures must be on a common circuit.
Wiring diagrams use standard symbols for wiring devices, usually different from those used on schematic diagrams. The electrical symbols not only show where something is to be installed, but also what type of device is being installed. For example, a surface ceiling light is shown by one symbol, a recessed ceiling light has a different symbol, and a surface fluorescent light has another symbol. Each type of switch has a different symbol and so do the various outlets. There are symbols that show the location of smoke detectors, the doorbell chime, and thermostat. On large projects symbols may be numbered to show, for example, the panel board and circuit to which the device connects, and also to identify which of several types of fixture are to be installed at that location.
A set of wiring diagrams may be required by the electrical inspection authority to approve connection of the residence to the public electrical supply system.
Wiring diagrams will also include panel schedules for circuit breaker panelboards, and riser diagrams for special services such as fire alarm or closed circuit television or other special services.

Three phase electric power is a common method of alternating current electric power generation, transmission, and distribution. It is a type of polyphase system and is the most common method used by electrical grids worldwide to transfer power. It is also used to power large motors and other heavy loads.. A three wire three phase circuit is usually more economical than an equivalent two wire ...
NEMA (National Electrical Manufacturers Association) 34 is a stepper motor with a 3.4×3.4 inch faceplate and 1.8° step angle. Each phase draws 4.0 A, allowing for a holding torque of 42 kg cm. NEMA 34 Stepper motor is generally used in Printers, CNC machine, Linear actuators and hard drives.
Fig. 11 - Phasor Diagram of Synchronous Motor. In order to draw the phasor diagram, Vt is taken as the reference phasor and below points are to be followed: If a machine works as a asynchronous motor then the direction of armature current will be opposite to that of the excitation emf. Phasor excitation emf always lags phasor terminal voltage.
2. Removed back flange plate on old motor and removed wiring and verified voltage connections for new motor. 3. Removed bolts holding motor to pump housing and backed motor out of the pump housing. 4. removed impeller and guard from old motor 5. Replaced all gaskets with new gaskets and lubed them where needed. 6.
