42 Series Hollow Cup Motor

Product Introduction
The 42mm hollow cup motor is optimized to ensure the best cost performance.
Thanks to the lack of slots and its compact structure, we get smoother high and low speed branches, more precise control, and higher efficiency and power density.
Widely used in intelligent home appliances, medical pumps, surgical instruments and other fields.
