Inverter comprising a part forming a set-back from a first part of the inverter
The invention relates to an inverter, notably configured to be on-board an automobile vehicle, comprising: power components configured to convert DC electrical energy into AC electrical energy so as to supply an electric motor, notably configured to drive the vehicle, a casing housing the components of the inverter and comprising a first part forming a first housing, housing said power components and a second part forming a second housing, housing filtering components configured to filter DC electrical energy supplied to the power components, notably from a battery of the vehicle,
said second casing part being formed at least in part by a set-back with respect to said first part from an outer face of the casing comprised in the first part.
CENTRIPETAL MAGNET ACCELERATOR
An assembly for generating electricity includes a circular track configured to rotate about a first axis of rotation, the circular track comprising a first magnet having a face that is at an angle with respect to the first axis of rotation, a second magnet positioned at a center of the circular track, wherein a face of the second magnet is an opposite polarity to the face of the first magnet such that the second magnet repels the first magnet to rotate the circular track, and a device for converting rotational motion from the circular track into electricity.
ACTUATOR FOR ELECTRONIC PARKING BRAKE
The present disclosure relates to an actuator for an electronic parking brake and, more particularly, to an actuator for an electronic parking brake, whereby a motor may be stably fixed using a simple structure. To this end, an actuator for an electronic parking brake according to the present disclosure comprises: a motor having a bracket to fix a position of a motor housing; a main housing in which the motor is accommodated; and a main cover seated on an upper end of the main housing, wherein a first fastening protrusion extending downward to be inserted into a first fastening groove formed in the motor housing and a second fastening protrusion extending outward in the radial direction to be inserted into a second fastening groove formed in the main housing are formed on the bracket, and when the motor is assembled, the second fastening groove supports the second fastening protrusion to prevent the axial direction movement of the second fastening protrusion.
Spindle motor
A spindle motor is provided, the motor comprising: a base plate, a PCB on the base plate, a bearing assembly arranged on the base plate, a stator coupled to a periphery of the bearing assembly, a rotor rotationally coupled to the bearing assembly, the rotor including a yoke and a magnet, and a rotation shaft rotationally coupled to the bearing assembly. The base plate includes a planar portion and a protruding portion arranged along with a periphery of the yoke, the protruding portion being apart from the yoke. The base plate is partially covered with the PCB in a region where the stator is arranged. And, a height from the planar portion to an upper surface of the protruding portion is smaller than a height from the planar portion to a lower surface of the periphery of the yoke.

Electric motor for a drive unit of a drive train test bench
An electric motor (1), for a drive unit (2) of a drive train test bench, having a housing (3). The electric motor (1) is characterized in that the housing (3) has at least one yoke (4) for supporting the electric motor (1).
WEAR INDICATOR FOR TRACK AND MOVER SYSTEM
The present disclosure describes a mover of a linear motor system. The mover includes a housing and a material coupled to the housing, the material having one or more protrusions extending towards a track of the linear motor system. The mover also includes a bearing to interface with the track. The bearing includes one or more recesses extending from a first surface of the bearing toward a second surface of the bearing, opposite the first surface. Each of the one or more recesses receives a respective protrusion of the one or more protrusions of the material. The bearing wears away from the second surface over time as the mover travels along the track, exposing the one or more protrusions to the track.

Bearing configuration for an electronic motor
Disclosed is an electronic motor with two bearings. The motor is structured so that, when loaded, the majority of the load (e.g., a radial load) is borne by one of the bearings. The bearing that bears a greater load may be larger and, thus, better suited for a heavy load. In some embodiments, the larger bearing may include rolling elements that have respective radii larger than respective radii of rolling elements of the other bearing by a ratio of at least 1.5 (150%). In some embodiments, the larger bearing may have an outer race with a radius that is greater than a radius of the outer race of the smaller bearing by a ratio of at least 1.5. In some embodiments, the motors may include a third bearing between the two bearings. The third bearing may reduce vibration in the motor.
Alternator and starter motor test fixture
A rotating-machine test fixture includes a base, a flexible member and a wedge member. The base includes a longitudinal axis and receives a rotating machine so that an axis of rotation of the rotating machine is aligned in a direction that is substantially parallel to the longitudinal axis of the base. The flexible member includes a first end attached to the base at a first location and a second end slidably attached to the base at a second location to hold the received rotating machine against the base. The wedge member is coupled to the base and moves in a direction that is substantially parallel to the longitudinal axis of the base. The wedge member may be selectably positioned between the received rotating machine and the base to align the axis of rotation of the rotating machine to be substantially parallel to the longitudinal axis of the base.
