Title:
ELECTRIC MOTOR, CONTROL DEVICE, AND MOTOR CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/072075
Kind Code:
A1
Abstract:
In this electric motor (10), electromagnetic force is generated among a plurality of permanent magnets (61) and coils (50a, 50b, 50c), and a magnetic bearing for rotatably supporting a rotating shaft (30) at the other end side in the axial direction thereof is configured. The configuration is such that it is possible for the rotating shaft (30) to incline with respect to the rotation center axis (M1), with a bearing (32) side of the rotating shaft (30) as the fulcrum. An electronic control device (70), using the electromagnetic force among the plurality of permanent magnets (61) and the coils (50a, 50b, 50c) as bearing power (Fa), controls the electrical current flowing to the coils (50a, 50b, 50c), in such a way that the axis (M2) of the rotating shaft (30) is brought near the rotation center axis (M1). In so doing, the rotating shaft (30) is rotatably supported by a single magnetic bearing and the bearing (32).
