A method for obtaining an initial mechanical angle of an electric motor includes determining a mechanical state of the electric motor, determining an initial electrical angle of the electric motor according to the mechanical state, and determining the initial mechanical angle of the electric motor according to the initial electrical angle.

In described examples of methods and control systems to control a position and/or velocity of a machine, control circuitry is coupled to receive and dither a control signal, and to compute a control output value according to the dithered control signal and a control function. An inverter is coupled to the control circuitry, to control the position and/or velocity according to the control output value.

A motor includes a shaft member in which at least a part of an outer peripheral surface is made of metal, a magnet unit which is configured by integrating a plurality of magnets and in which a press-fit hole into which the shaft member is press-fitted is formed, a substrate which is disposed at a predetermined distance from the magnet unit in an extending direction of the shaft member and to which electric power is supplied, and a protective member in which a through-hole into which the shaft member is inserted is formed and which is disposed between the magnet unit and the substrate in the extending direction of the shaft member. In the motor, the protective member is in contact with at least a part of the outer peripheral surface of the shaft member.

A self-driving vehicle with an integrated fully-active suspension system. The fully-active suspension utilizes data from one or more sensors used for autonomous driving (e.g. vision, LIDAR, GPS) in order to anticipate road conditions in advance. The system builds a topographical map of the road surface. Suspension and road data is delivered back to the vehicle in order to change autonomous driving behavior including route planning. Energy storage is regulated based on a planned route. Forward and lateral acceleration feel is mitigated through active pitch and tilt compensation. The fully-active suspension pushes and pulls the suspension in three or more operational quadrants in order to deliver superior ride comfort, handling, and/safety of the vehicle.

A rotation apparatus includes a first disk-shaped rotation body capable of rotating around a first rotation axis, a plurality of first permanent magnets arranged at a peripheral part of the first disk-shaped rotation body so that N-poles and S-poles thereof are distributed alternately, at least one pair of electromagnets arranged at static positions with a predetermined interval, and a pair of sensor switches for respectively detecting rotational positions of the N-poles and the S-poles of the plurality of first permanent magnets and for electrically energizing the at least one pair of electromagnets. One electromagnet of the pair of electromagnets is energized based on a detected result of the pair of sensor switches to move the first permanent magnet adjacent to the energized electromagnet, by an attractive force and a repulsive force between the energized electromagnet and the first permanent magnet so as to rotate the first disk-shaped rotation body.
