I require 12v BLDC sensor-less motors for operation of models. Initial SKU would be apx. 10-15K per year ongoing.We would require motor sizes of 8-10mm, and 15-20mm Maximum, and length of 18-20mm and 30-40mm maximum. All sizes can be discussed of course.The motor must be reversible and, a low rotation speed (max 22000 rpm less is better)Torque requirements are not high, (apx.15g-cm) higher is acceptable,We are also seeking manufacture of a control PCB for this motor.This is a serious enquiry, and if you are able to help, I am currently in Hong Kong, and would be able to meet for a discussion either Saturday 30th or possibly Tuesday 2nd December before I return to the UK. Unfortunately I am travelling in China today, and will not be able to receive email until late this afternoon. I realise this is short notice, and would be happy to correspond by Email if you prefer.
