SOURCE: Wiring the replacement 3 speed switch (fan motor)

I called King of Fans and the rep that I spoke with gave me the correct wiring for the 3 speed switch:

L White
1 Yellow
2 Blue
3 Black

The problem is that after I wired it this way I am getting the same result (off on 3 settings and a motor hum on 1 setting). So, either the Westinghouse switch that I bought at Home Depot is not compatible or it is the capacitor. The saga continues.

There should be 2 contactors for forward and reverse. you have to wire them so that the power coming in will switch 2 opposite phases to reverse.

I am in the process of replacing a capacitor on a Craftsman 6 in 1/3 grinder, 2.8 amp, single phase, 110v. Not sure on the centrifugal switch. model 319.190621, ser B9530. When I took the old one out the black wire from the capacitor went to the cluster of back wires (in my case 3) in the wire nut. The blue wire from the grinder went to red wire from the capacitor in a wire nut. Hope that helps you....

Maybe you can help me... the specs on the capacitor burned off when it failed. Can you tell me what the capacitor specs are on yours?

How do I reverse a three phase electric motor?


Reversing rotation of 3 phase motors:
CAUTION: Before attempting any repair of electrical equipment verify the power is disconnected to the device.
CAUTION: Three phase motors could potentially be controlled by frequency control systems. It is recommended a trained electrician perform repairs to any electrical system. In particular, consult a trained electrician if the system includes a frequency control system.

Most 3 phase motors can reverse rotation simply by swapping any 2 of the 3 phase wires. A typical 3 phase wiring circuit will include a safety ground wire (usually green) and 3 phase wires, often designated A/B/C, or 1/2/3, or color coded to distinguish each. By swapping the terminal connection of any 2 of the three phase wires, for example, 1 & 2 or 2 & 3 or 1 & 3, but leaving the third phase wire unchanged will reverse the rotation of most motors.

Tip

How to Reverse the Rotation of Single Phase Capacitor-Start Electric Motors


Reversing the rotation of electric motors can be done easily with 3-phase motors. This can be easily achieved by swapping the connection of any two motor leads. But 3-phase motors are usually found and used for industrial purposes. The ones found and used in our homes, from water pumps to electric fans, are single phase capacitor-start type motors. Unlike 3-phase motors, reversing the rotation of single phase electric motors is no easy task. Swapping any two motor leads will not result in the reversal of the motor rotation. Analysis of the motor windings and connections are necessary before any modification can be done to achieve the desired result. Let's take a 3-speed single phase capacitor-start electric motor with electrical diagram shown below as an example. Make sure the motor is disconnected from the power supply before attempting to follow this tip. This tip is intended only for individuals with electrical knowledge, necessary tools, and understand the risks associated with handling electrical equipments and devices.

The first step in the process is determining the start winding which is connected to the line (AC white) and to one side of the start capacitor. To accurately determine the start winding, disconnect all motor leads from the start capacitor and the speed switch for multi-speed motors and then setting your ohmmeter to the lowest scale (R x 1), measure the resistances between the AC white line and each of the motor leads connecting to the start capacitor. The one with the least resistance is the starting winding lead.

Once the start winding lead going to the capacitor is determined, reconnect the capacitor then connect the black AC line to the found start winding lead (marked X). Connect the white AC line to L of speed switch, the motor lead formerly connected to AC white to 3, red to 2, and white to 1 as shown below. Leave the green/yellow ground wire connection as is.

2 speed switch wiring dieagram


The motor will have wiring diagram and voltage on nameplate.
You can re-post question with information that shows on nameplate for more exact information, or keep reading below:
If motor is rated for 240Volts, then it will not work with 120V.
If motor is rated for both 120V and 240V, then either Low voltage or high voltage will work, and one wire will be common, and 1 wire will for 120 and other wire for 240.
If motor is rated 120Volt two speed, then one wire will be neutral, and 1 wire low speed, and other wire high speed. You can connect your wire to either low of high, and cap other wire.
If motor is 240volt two speed, then one wire will be common, and 1 wire low speed, and other wire high speed.
If motor is rated 3-phase, then all three wires are connected to the voltage shown on nameplate.
If motor is rated 3-phase two speed, you may need electrician to wire the motor correctly.

I have Delco Model 2J2424r1, frame 56R, Series A84, phase 3 electric motor. What is the wiring diagram to run it under 230VAC?


If it has 9 leads and is a 240/480 volt motor the 1and 7 go to line 1. the 2 and 8 leads go to line 2 and the 3 and 9 leads go to line 3. the 4 5 and 6 leads are hooked together with a wire nut. To reverse rotation simply reverse any 2 of the line leads.. Prairie Dog........

Too change rotation of a 5hp 230 volt


HAVE A LOOK INSIDE THE MOTOR CONNECTION BOX. SOMETIMES ON THE LID ARE INSTRUCTIONS OF HOW TO DO THIS. YOU DID NOT SAY IF THIS WAS A CAPACITOR START UNIT OR NOT. IF THERE IS A CAPACITOR ON THERE IT COULD BE NO GOOD WHICH WILL MAKE THE MOTOR GO WHERE IT WANTS. A GOOD CAPACITOR KICKS IT IN THE RIGHT DIRECTION ON SWITCH ON.

I would like to connect a pressure switch to the motor starter


hi! there, single phase compressor motor need a starting capacitor base on the rated capacity in horse power,you can check this on the tag of the compressor motor how many horsepower was indicated,it should be for single phase motor starting capacitor has a capacity of micro farads.for a 1 horsepower = 15 to 18 micro farads stating capacitor if you have more than 1 horsepower you can basically proportion the value of capacitor you need or ask the dealer how much capacitor you need on your motor the connection of pressure switch with a four terminal should be connected both on common line L1 and running capacitor line L2 .if you open the cover of pressure switch there are 4 terminals,2 terminals are connected when normally close or no pressure they connected on series connection on the common line one terminal connected to common line of the compressor and the other terminal on L1 to the pushbutton switch to L1 supply line.the 2 other terminals also connected in series withe line capacitors L2 to yhr power supply line.hope this will help you a lot.just rate my fix thanks a lot.

Hobart model 5801 meat saw conversion from 3 phase to single phase can it be rewired or need a new motor ?


No, you need a new motor or a converter, but in the case of one saw, it wouldn't be worth the conversion. Just find an old single phase motor that will fit height wise and you should be all set. The speed is the same, the direction can be switched and the HP should not matter much, 1/2 , 1, depends on what you find out there. They all should cut wood no problem. Hope this helps.

from what you are describing it sounds like you are missing a couple wires somewhere or you do not know what you are looking for. The pressure switch, low oil switch motor starter coil, and overload relay should be wired in series to provide a control circuit for the motor starter. I would highly advise seeking the help of a certified electrician if you are not experienced in working with these machines. You can not only risk personal injury, but also damage a lot of expensive electrical item's real quick if it is not done correctly.
