Three Wire Electric Motor

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

Three wire electric motor.

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. They can also be found in large residential complexes and appliances requiring a large amount of power.

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. 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. Although these systems may seem intimidating at first a walkthrough on 3 phase wiring for dummies will help clarify the whole situation.

Most electric motors have a wiring junction box typically on the rear of the motor on one side. 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. This is where the cord or conduit attaches. In this case if the black wire is the hi then the motor spins terribly slow.

Three phase electric power is a common method of alternating current electric power generation transmission and distribution. Changes in the wiring of an electric motor should only be made after the electric motor circuit has been identified and turned off and tagged. L1 to t1 l2 to t2 l3 to t3 t4 to t7 t5 to t8 and t6. These tips can be used on most ele.

A three wire three phase circuit is usually more economical than an equivalent two wire. Three phase motors are more efficient than single phase motors and are commonly found in applications requiring more than 7 5 horsepower.

Motors that are designed for 120 240 volts.

Different regions may use different voltages. I show how to wire several different types of motors and explain some of the important components. Wiring an ac electric motor is not particularly difficult if the manufacturer s manual is available. In this video jamie shows you how to read a wiring diagram and the basics of hooking up an electric air compressor motor.
