Single Phase capacitor start capacitor run electric motors, often referred as cap start cap run motors, are able to handle applications that are too demanding for any other type of single phase electric motor such as a permanent capacitor motor. High starting performance means that cap start cap run motors are suitable for agricultural, high pressure washers, vacuum pumps, conveyors, and refrigeration equipment which all demand higher starting torque. The advantages of capacitor start capacitor run motors are their high starting torque, their ability to run either clockwise or anti-clockwise with a change of connection and their cool running to comparable kw powers. All our single phase cap start cap run motors have a light weight aluminium frame and have an IP55 protection rating giving dust protection and protection from low pressure jets of water meaning the operating conditions can be preserved inside the unit in most working environments. These single phase capacitor start capacitor run electric motors also have an IE1 (Eff2) standard efficiency rating. B14 motors are flange mounted.

Why are you including this one?? It is flange mounting.
The others are ,foot mounted known has B3 for some reason.

If I am supplying motors for a job, I will use TEC - usually for price sensitive customers or Marelli which seem to be a little better quality but usually dearer. Possibly nothing wrong with other makes but as I often have to take them apart, I prefer to stick with ones that come apart easily or at least I know how to do it.

Glad to see you are searching for yourself and hopefully learning on the way.

Engineers mate is a good seller to deal with IMHO

I was having a little nose at that one,but it's been a long time since I did motor theory so I'm not the best to advise.
What I did note though was the speed, doesn't the original turn slower? I can't quite make it out from your pics but it looks like 23something something.

Nominal speed for induction motors run on UK 50Hz mains is given by 3000/N where N is an integer. (3600/N in USA)
N= 1/2 the number of poles too.

eg 3000, 1500, 1000,750 etc In practice the actual speeds are a few percent lower
eg 2850, 1425, 950,670 etc.
eg 2pole,4 pole,6 pole 8 pole etc the number of poles is always be even

Cool, thanks Bob.
So if you apply, is it called slip factor or something like that, the quoted speed will be lower and match up with Mock's original motor speed?
Like I said it's been a long time since I did motors :shock: :lol:

WOULD THIS SUIT USE AT FIX SPEED ??? Marelli 90L Frame - 2.2kW (3HP) Single Phase Capacitor Run 2 Pole AC Motor for use at fixed Speed.

Use with a fixed frequency 1ph input at 230V x 50Hz for 2.2kW x 2820RPM.

Full Load Current -xxA.
Starting Current is xxA.

Mounting is B3 Foot Mounting.
Foot mount on 10mm holes at 140mm wide x 125mm centres 56mm back from shaft shoulder.
Shaft is 24mm dia x 50mm long with 8mm wide key.

Rated at 40C Ambient.
Ventilation space required at rear cooling air intake.

Full part number is - MYA90L2 B3

What is your question other than that which is answered in the first line?

 

[user 19915]

The question is do i need a fixed speed motor

 

[Myfordman]

Did you not read my reply to nolegs??

Single phase motor speeds are fixed by the frequency of the supply and the number of poles. I even gave the formula to work it out.

You have no option but to have a fixed speed motor. You have already ruled out variable speed by rejecting the use of a perfectly good three phase motor.

 

[user 19915]

Well you will be pleased to know Myfordman i have ordered a motor so a little peace and quiet for a while so thank'you .
AND THANK;S EVERYBODY ELSE THAT HELPED most appreciated MOCK =D> =D> =D>

You asked about a price for selling you're original 3 phase unit, here's one, Off a startrite saw bench!

[user 19915]

Thank;s at least i have a guide

 

[user 19915]

I.m now after a switch for my table saw 275 single phase any suggestions the original switch was broke when i purchased the saw
mock

 

[blackrodd]

What details on the motor, hp, etc

[user 19915]

hope you can see this

 

[user 19915]

next question can i use the cable from the 3 phase motor ? And if so where do they go PHOTO OF THE 3 PHASE AND THE SINGLE PHASE
