5 Torque figures

The torque figures detail motor torque characteristics for half step operation in order to allow simple

comparison. For half step operation there are always a number of resonance points (with less torque)

which are not depicted. These will be minimized by microstep operation in most applications.

5.1 Motor QSH4218-35-10-027
