Motor Link to heading
Baratza have at least 3 variants of motor used in the Vario… and 120V/230V versions of each:
* PN: 1036 / 1037 D-shaft motor * PN: 1058? / ?? Helical shaft motor * PN: 6026 / 6027 Hybrid shaft motor
There’s also two styles of motor enclosure used:
not sure if these relate to specific part numbers above or not though, or it might be a Mahlkonig vs Baratza difference.

6027 230v Motor (hybrid) - DCT-M-003 https://www.coffeeparts.com.au/bt-6027-230v-motor
Note: the Sette 270 commonly has the DCT-M-004-D motor, marked as 14000RPM (https://imgur.com/a/7DAejoU).
I suspect that one/some of these motors may be build by Johnson https://shop.johnsonelectric.com/categories/dc-voltage-motor
The Intertek label on the left motor above is the regulatory body that’s certified the motor for sale.
Vario vs Forte Link to heading
Both the current Vario and Forte parts lists have the 6026/6027 as the listed motor for use - the hybrid one is supposed to be used for all current models.
However, the Forte uses a different drive ratio, it runs faster with a wider tooth belt.
Vario:
* Motor pulley: 18 teeth
* Burr pulley: 96 teeth
Drive ratio: 5.33
Forte:
* Motor pulley: 17 teeth
* Burr pulley: 68 teeth
Drive ratio: 4.0
In Australia at least it’s easy to get the Forte drive: * https://www.coffeeparts.com.au/bt-1056-main-drive-pulley-with-metal-sleeve * https://www.coffeeparts.com.au/bt-1090-gt3-motor-drive-pulley * https://www.coffeeparts.com.au/bt-1027-gt3-belt * https://baratza.com/wp-content/uploads/2021/02/forte-plev-v4-020421.pdf
