Brushless dc motor with large air gap

open access: yesElectrical Engineering in Japan, 1997
The authors propose a new brushless dc motor for pumps, with a large air gap of 8 mm, compared with the conventional gap of 1 mm. The conventional pump system is composed of an induction motor, a magnetic coupling, and a magnetic rotor with vane. This rotor receives power from the magnetic coupling.
