Collection of onan generator wiring diagram. It reveals the components of the circuit as streamlined forms and the power and signal links in between the tools.
The first step is to figure out the voltage of your phases. If the motor is too large for the generator the generator s voltage dips greater than 30 percent. The 3 phase revolving field generator is constructed by placing the three sets of single phase windings 120 mechanical degrees apart on a metal core around the inside of a metal housing that supports the core the stator assembly.
The 3 phase revolving armature generator. As shown in figure 2 an electromagnet placed in the center of. A wiring diagram is a simplified traditional pictorial depiction of an electric circuit.
The three coils are equally spaced 120 apart around the inside of the stator. 3 t 4 l 2 12 lead 11 8 t 9 t 12 t 7 t 10 l l0 l l l l0 l l l0 j single phase kw kva ratings are approximately equal to 50 of the generator s three phase ratings. That being said there is a wide range of different motors and what you have on hand can be completely different.
In the united states for low voltage motors below 600v you can expect either 230v or 460v. This may result in the motor starter de energizing or the motor stalling. The three phase utility power as l 1 l 2 l 3 n are directly connected to the upper side of manual changeover switch while the backup power of three phase generator is connected to the first four right slots of at lower side.
