We ordered the motor and its gearbox!
After some consideration, we decided to use a single phase 1 HP motor with a 20:1 worm gear reducer. We decided to order these first so we can get an idea of how we want our frame for the shredder.
Originally, we wanted to make it a higher horsepower so we can shred harder plastic, but since we’re making this for our school, the main plastic waste will come from bottles from beverages, so we decided on a 1 HP motor.
