Thank you for your suggestion. Unfortunately, we are unable to send our housing of blender as your requested, because of this new model 7625/7630 will instead of existing model 6330. We have got change some dimensions and add the cooling blade (big fan) for implementing performance that might help to resolve the current problems of blender motor. Therefore, now we do not finalized the housing of this. Could you please us with the torque curve for our review before working further on the sample’s sending as for our performance test? By the way, please let us know about the motor specification i.e. the tolerance that can be controlled of stator thickness and other dimensions, high volt test, insulation resistance, insulation class F, and electrc capability at free load/on load (with the tolerance). Thank you for your kindly support as always.
