Title:
COMBINATION MOTOR
Document Type and Number:
WIPO Patent Application WO/2011/000249
Kind Code:
A1
Abstract:
A combination motor includes a vacuum sealed chamber (33). An upper levitating magnetic ring (23), an upper coil group (11), a magnet group (25), a lower coil group (12) and a lower levitating magnetic ring (24) are disposed in the sealed chamber (33) in turn from top to bottom. The upper and lower levitating magnetic rings (23, 24), the upper and lower coil groups (11, 12) and the magnet group (25) are sleeved at a rotating shaft (31). A top magnetic ring (21) is disposed above the upper levitating magnetic ring (23), and a bottom magnetic ring (22) is disposed below the lower levitating magnetic ring (24). The combination motor employs the vacuum sealed chamber (33) to permit various elements of the motor to be disposed in a closed environment so as to reduce the resistance during the rotation of the motor.
