Worm Gear Motor ZD1631L 6-35Nm 45 and 65 RPM
These are traditionally built and used for car wipers, but they can also be run as a highly efficient worm drive motor.
This particular unit has extremely tight tolerances (zero backlash) and an ultra smooth motor and gearbox.
While it is operating you can barely hear it, that's how quiet the motor and gearbox are.
This smaller unit has a rating of 6nM, and will overdrive to a maximum (and stall at) 35nM. It is an extremely powerful motor for its small size.
It operates from 12V and has 2 operational speeds (either 45 RPM or 65 RPM - User selectable speeds)
These are a good choice if you are on a budget simply for the fact you can overdrive them with little more than some extra current. The worm will actually stall at 35Nm but it will only hold torque to about 80% of its rated load (so between 5-6nM).
There are a few different manufacturers that make this motor and gearbox combination with the same name (or similar), but we believe we've found the best. This is an extremely well built unit and represents great value for the cost.
To connect these as a normal worm drive, hook the Negative to the chassis of the unit, and positive to either the White wire or Blue wire for low or high speeds.
