Getting replacement DC Motor for Hitachi Wand Massager

I have searched all the numbers off the motor & can't find anything.

I don't even know what voltage & wattage to look for. Only know its 6000rpm is the highest setting.

Here is a pic inside with what info I could read from the inside parts.



Can anyone tell from this what the specs are?

thanks

Many motors for consumer products are custom made for that application. They usually do not use standard, off-the-shelf motors. The manufacturer is probably the only source for a direct replacement.

What you have pointed to are diodes, not the motor. If one of them is bad you can probably find a suitable replacement.

They don't make this device any more, no chance of anything from the manufacturer. How do way I find what the voltage & wattage is?

thanks

It is probably whatever voltage is used in your country. Wattage look at the label on the device if it has one. In the USA the label will say both it's voltage and wattage or amps.

It's input is 110 V ac & runs a DC motor, no transformer or anything but what is in the pic. Would that mean its 110V DC?
I'm wondering if its safe to use a voltmeter on the motor terminals.

Yes... you can use a voltmeter on the motor leads. The motor voltage will be somewhere around 155-170vdc. Depending if in high or low speed.

The circuit uses four diodes to convert the AC to DC and the fifth diode is put in series to reduce voltage in low.

Depending where you are located you might be able to get the motor fixed easier and cheaper than finding a replacement. In Costa Rica my electric lawn mower motor died and it was very cheap to have it re-wound and it's been running great since. Repair shops are more scarce in the US but in many countries they still fix things instead of throwing away.

The motor is 6 volts DC. I know because I tested it with a voltmeter.

Please, tell us how you tested the motor's voltage with a volt meter. And please tell us how 6 volts is created to feed the motor.
