Design
BO4221 Series Motors are Brushless DC Outrunner motors with 43mm diameter and 21mm height. These Motors are available with sensor and without sensor. Robust Ball bearings ensure excellent service life with ≥5000Hrs. Drivers are also available as an Add-On unit on special request.These motors are available in different speeds and different voltages on special request. In order to reduce motor height, we can use FFC cable also on the special request.
