Title:
MAGNETIC POWER TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/016135
Kind Code:
A1
Abstract:
Provided is a magnetic power transmission device capable of improving the power
transmission efficiency and transmission capability while maintaining the
merits obtained when performing power transmission by using a magnetic force
and reducing the manufacturing cost. The magnetic power transmission device
(1) includes: an external rotor (11) having a plurality of left and right permanent
magnets (11c) arranged in the circumferential direction; an internal rotor
(12) having a plurality of permanent magnets (12c) arranged in the circumferential
direction; and an intermediate rotor (13) having a plurality of left and right
soft magnetic bodies (13d, 13e) arranged in the circumferential direction.
When the left and the right permanent magnets (11c) are positioned to oppose
to the permanent magnets (12c): if the left permanent magnet (11c) has a polarity
different from that of the left side of the permanent magnet (12c), the right permanent
magnet (11c) has a polarity identical to that of the right side of the permanent
magnet (12c); and if one of the soft magnetic bodies (13d, 13e) is positioned between
the permanent magnets (11c, 12c), the other is positioned between the two adjacent
permanent magnets (11c, 12c).
