Sorry for late reply, attached please find a copy of our quotation for your perusal. Please take note that I am quoting you the new DR series of motor as DV series of motor is no longer in mass production. In case you must have the DV series of motor, I will check with supplier but the price is definitely expensive.
Attached please find the data sheet for the DR series of motor for your checking with your end-user.
Please feel free to call me should you have any question.
