Replacement stepper motor for Taz5

Hi all,

My stepper motor is cactus (broken) and needs to be replaced. It is a SY42STH47-1504A. Does anyone know what direct replacement equivalents there are? Are Nema 17 steppers directly compatible? What model number would I need?? Do the Nema steppers also have a ‘D’ shaped shaft?
Appreciate your help!

There is a direct replacement motor for sale in the lulzbot store. NEMA motors have a standard mount but there are different types of motors, shafts, voltages and pinouts to be aware of. A replacement from another source will probably work but might not.
