Performance curves are based on new rotor and stator dimensions and for reference only. Actual performance may vary depending on fit
and drilling conditions. The stall torque may exceed that specified for the connected components. Operating over the recommended limits
may result in damage to the power section and connected components. Please visit basintek.com for the latest specification revisions.
