Parvalux motor

Good afternoon all,

I need a 24 v dc supply to operate a Parvalux motor.

Any ideas how to go about it since I have only AC to hand 110,230 380 v

I do not have a 24v battery, nor any means of charging one.

Thanks in advance for any advice.

Just get a 240v in 24dc SMPS ( switch mode power supply) off eBay you should only need a 5 amp

Such as

Or this style

Most, if not all Parvalux "DC" motors are brushed "universal" motors. This means they will run fine on AC, You just need a 24 V transformer (a dual 12V will do too).
A SMPS is overkill and may not actually work depending on the size of the motor and the design of the SMPS. Many do not like the inrush current of a DC motor with a heavy load. I'm not sure how Ian determined a 5A requirement.

Personally I would not touch that with a barge pole (unless it was certified as insulating )

Clearly not compliant with regulations, it does not even have a part number. I would be concerned about it' safety.

Well assuming its the one i linked to the other day 5 amps is plenty

the motor will run fine on either of those PS

That motor is a PM ( permanent magnet ) motor so wont run on ac

Rather unlikely I think. A 24V motor is most likely to be a PM type or possibly shunt wound field.

One piece of advice is just ask the question you want to have answered. Like I need a 24 DC supply at around 5 Amps. That way you won't get everyone and his dog second guessing what your motor is.

;O)

OK Martin, that,s what I need.

If, as suggested, you used two 12V batteries you would need some way of charging these. Could this be a conventional car battery charger and is there some better way of maintaining charge in a car battery off the vehicle?
