SOURCE: Alarm mode question

sounds like battery failed, check the connections and clean them, then try it again. see if the battery is ok, check voltage, and shake the battery, if you hear little objects rattle inside, it is bad. i hope this is helpful,good luck,glen also consider the unit could be shot.

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.

SOURCE: Is the Delta 31-380 edge sander a 1 phase or 2

It appears that it could be either, they show 2 motors for this tool and list 1ph or 3ph. Is their a nameplate on the unit that would indicate the proper voltage? If not let me know and I will dig deeper.

SOURCE: replaced century 1/6hp fan motor

Hi,

If you only have two leads on that motor then it is not a reversible motor or there is another way to reverse it...

Are there other wires with a plug connecting them on the end of the motor? If so then you reverse the rotation there... sometimes there is a switch in the side of the motor...

If there is none of this then you need to get another motor because the one you have is running the wrong way and will not work...

How to reverse rotation of single phase, 1/2 HP, 110V electric motor.


Changing the "polarity" of the start winding by swapping the wires over should reverse the direction. Lots of online motor-related generic and manufacturer information is available.

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.

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.

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........

I have a 1/3 hp motor with a capacitor. There are four motor leads coming out of motor, the capacitor is mounted in the wiring box. This motor does not have a centrifugal switch, to isolate the capacitor...


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?

Model 1456 n19811 how to reverse conveyor


If it's 3 phase, just reverse 2 of the 3 motor feed wires. It doesn't matter which 2. If it's single phase, the wiring directions should be inside the motor where the wires go in.

Using dryer in 220V country


There are two systems in use in the states
110v dryers are available that fit a standard 11v 15a socket
110/220v fit the oversize 'dryer' sockets, and they are two 110v phases 90 degreees apart
the motor runs of a single phase 110v.
there is 220v between the 'outside', the active lines of the two phases, at any time, but it is not useable to provide mechanical power as a single service, due to the complicated shape of the wave form when you add out of phase voltages together, but is ok to drive the heaters, they have no mechanical efficiency requirement
A 2 phase 110v heater it means 3kw can be supplied without a 30 amp circuit
but it becomes difficult to use a single phase 220-240v transformer to provide 2x110v 90degree 2 phase current unless you specially buy one in. .
High power applications in 220-240v are generally supplied by 415v 3 phase 60deg supplies,

Any transformer would be onsellable at the end of your posting, to your replacement, who would doubtless be in the same boat as you, with a heap of 'stuff' that needs to run.

UK Aus NZ may be sources of transformers, or dryers to suit.
check with Australian UK NZ suppliers as well as local Indian ones, as those countries are also nominal 240v single phase home suplies and they may have (1) the dryer, or (2)the transformer to suit the 110 2 phase dryer
