eletric motor

Hi Jonathon,
I suspect that Clarke do not make motors.They probably get a motor manufacturer to make them an put a Clarke badge on them. I would not pay £110.00 for a 1/2HP Clarke motor when Machine Mart sell the 2 pole one for £75.79 and the 4 pole one for £83.98 The Clarke motors look like they have two capacitors so there is no difference in the specification. If I was buying one I would get the one on Ebay. (I spotted one at £68.00) Most of the new motors on Ebay seem to be manufactured by TEC (Chinese.) I bought a 1HP three phase TEC motor and it works fine and looks well made. By the way I have never seen a washing machine with any type of induction motor fitted. All the ones I have seen have a series wound motor. (Also called universal.)

I would pop down to the local electrical engineers or rewinders, they will probably sell you a British made 1/2 hp for about £25 to £50 second hand, far bttr bet than italian or chinese. I have noticed that some of the Clarke motors hum very loudly which is a clear indication of a poorly wound and therefore inneficient motor.

All the old wringer type washing machines had either 1/4 or 1/3hp induction motors, split phase ie. no capacitor. The Hoover Twin Tub of the same era had universal motors. Here in NZ, if you pay more than $NZ25 you'r being ripped off for an old 1/4hp motor. If there is a bit of a load to start against maybe cap start would help, but I run my wood lathe on a 2/3hp split phase motor ex an old petrol bowser (it's flame proof).

FWIW I have a 3-phase 1/2 HP Tec from Transwave on my lathe and it's smooth as silk.

Hi Jonathon,
In your post at 13:54 you imply that Clarke motors need a starter and others do no. All induction motors should be used with a starter which provides overload protection and a no volt release function (To prevent it starting by itself after a power failure.) A lot of people use motors without overload protection and even without a no volt release switch.

I was there with my Lister A, not in the main area as when I turned up early Friday morning there was no longer any space so I and others were put between the Rally office and Craft tent.

The motor starter from Machine Mart does not have no volt release, it's just a push button switch with (perhaps) a thermal trip. Tool Station stocks reasonably priced DOL starters and overloads, the case and insides are fine but the moulded push buttons are a bit fragile.

Hi Jonathon,
I've just noticed that there is a 1/4HP motor for £15.00 in the "for sale" adds on this site if it is powerful enough for your needs.

Les.

www.inverterdrive.com are good for motors.

Jonathon,

If you are in Cambridge, UK, you might like to contact Shoebridges in Stanground, Peterborough. They rewind and repair motors, and so could help, if only with advice. And they are about forty miles away.

They got me out of trouble, saving buying a new motor, when I thought that the motor on my Myford had gone west.

Hi Jonathon,

The function of starters as 'stoppers' is perhaps more important than as starters.

Their 'no-voltage release' safety function is to stop the machine starting on its own when power is reapplied, obviously the potential; for destruction and mayhem is much less with a vacuum cleaner than a lathe.
