1 Features

These two phase hybrid stepper motors are optimized for microstepping and give a good fit to the

TRINAMIC family of motor controllers and drivers. They are also used in the 57mm PANdrive family.

Main characteristics:

• NEMA 17 mounting configuration

• flange max. 42.2mm * 42.2mm

• 5.0mm axis diameter, 20mm axis length

• step angle: 1.8˚

• optimized for microstep operation

• optimum fit for TMC236 / TMC246 based driver circuits

• up to 42V operating voltage

• 4 wire connection

• neodymium magnets for maximum torque
