Hi,

In my opinion the best motor for this applications is the classic asyncronous 3ph motor. With capacitor properly connected you can run it with 1ph power supply no needing inverter or any other devilry.
The price of 2Kw brand new motor without gearbox starts from 150Euro, but this kind of motor is quite easy to find used in scrapyard or ebay at low price, often with gearbox mounted.

Changing form 3ph to 1ph adding capacitor, the motor loses a lot of its starting torque, but in shredder application it’s enough start the motor with no plastic inside the hopper.

Ciao

Hi,
This is really a bad luck!

Perhaps you can save your shredder using bering spacers.
They starts, if i remember well, from 0.1mm thick and seems to me 0.2 and 0.3mm is also available.
It’s enough find one with compatible inner diameter.

Ciao
