Three Wire Electric Motor

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.

Ac single phase 1 4 blower motor brushless induction. It is also used to power large motors and other heavy loads. Wiring an ac electric motor is not particularly difficult if the manufacturer s manual is available.

These tips can be used on most ele. Motors that are designed for 120 240 volts. This is where the cord or conduit attaches. Three phase electric power is a common method of alternating current electric power generation transmission and distribution.

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. 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. I show how to wire several different types of motors and explain some of the important components.

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. Different regions may use different voltages. They can also be found in large residential complexes and appliances requiring a large amount of power.

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

It is a type of polyphase system and is the most common method used by electrical grids worldwide to transfer power. But if the manual cannot be found the job becomes tougher. In this case if the black wire is the hi then the motor spins terribly slow. If the wiring schematic.
