It is also used to power large motors and other heavy loads.

Three wire electric motor.

In this case if the black wire is the hi then the motor spins terribly slow. Motors that are designed for 120 240 volts. These tips can be used on most ele. But if the manual cannot be found the job becomes tougher.

Three phase electric power is a common method of alternating current electric power generation transmission and distribution. The other 9 wires would be connected as in a 9 wire motor note in a 9 wire motor the equivalent of t10 t11 and t12 are internally connected together. I show how to wire several different types of motors and explain some of the important components. It is a type of polyphase system and is the most common method used by electrical grids worldwide to transfer power.

In all cases if you re unsure about how the motor should be connected consult an expert as incorrectly wiring a motor can lead to a shocking hazard or injury. Wiring an ac electric motor is not particularly difficult if the manufacturer s manual is available. L1 to t1 l2 to t2 l3 to t3 t4 to t7 t5 to t8 and t6. This is where the cord or conduit attaches.

In this video jamie shows you how to read a wiring diagram and the basics of hooking up an electric air compressor motor. Although the national electric code does not specify specific conductor colors for three phase current it is common to use black red and blue wires to identify lines l1 l2 and l3 respectively. Most electric motors have a wiring junction box typically on the rear of the motor on one side. On a 12 wire motor wired for high voltage i e 480v 10t 11t and 12t must be connected together but not connected to anything else.

Three phase systems are extremely common in industrial and commercial settings. Although these systems may seem intimidating at first a walkthrough on 3 phase wiring for dummies will help clarify the whole situation. If the wiring schematic. Three phase motors are more efficient than single phase motors and are commonly found in applications requiring more than 7 5 horsepower.

Different regions may use different voltages.
