Typically, the one or more modules can be removably coupled together based on a need of a user.

A method for producing an annular winding head support for a rotor of a rotating electric machine. In order to be able to produce a winding head support for particularly large machines in a simple manner, ring segments are created, after which the ring segments are connected to create a ring that constitutes the winding head support. In addition, the electric machine has a stator and a rotor, with the rotor including at least one winding head at an end side. A winding head support is provided in order to accommodate centrifugal forces occurring during operation.

Techniques described include refurbishing a rotor of an electric machine such as an electric generator by assembling replacement modular bars in lieu of certain non-modular bars, such as amortisseur bars. The replacement modular bars are provided in different threaded sections based on their location on the rotor, with the sections then threaded onto each other.

The invention discloses a modular robot joint, encoder reading head position adjustment mechanism and method for adjusting the position of an encoder reading head, the encoder reading head position adjustment mechanism is disposed on one side of the encoder reading head bracket, and includes a lower support and a upper support, the lower support and the upper support are connected to each other and positioned by a positioning connecting member, the upper support is pressed tightly against the lower support by a pressing connecting member, the encoder reading head is fixed to the upper surface of the upper support and is opposite to the encoder magnetic ring, the encoder magnetic ring is fixed to the motor shaft or the hollow shaft, the distance between the lower support and the upper support can be adjusted by adjusting the pressing connecting member and positioning connecting member, so that the axial distance between the reading head and the magnetic ring can be adjusted to a predetermined value, the processing accuracy of related parts on the dimensional chain is reasonably reduced, and the processing cost is reduced too, and the relative distance between the reading head and the magnetic ring is easy to adjust when the robot joint is assembled and debugged, thus achieving good technical results.

A system (100), electromagnetic actuator (102) and track (101) for braking are provided. The actuator (102) includes pole portions (109) extending from back-iron portions. Respective longitudinal axes (104) of the pole portions (109) are arranged about parallel to one another and about perpendicular to a common movement axis (104). A pole pitch of the pole portions (109) is selected to induce eddy currents in a segmented track (101), such that the eddy currents are present in a skin depth at more than one surface of segments (105) of the segmented track (101) when the pole portions (109) are moving at given speeds. Eddy current generated losses occupy about an entirety of a volume of a segment (105) of the track (101) below a given intermediate speed, and the eddy current generated losses occupy at least one third of the volume of the segment (105) at a given maximum speed greater than the given intermediate speed. Individually controllable electrical windings are around respective pole portions (109).

An axle driving apparatus with an electric motor is used in a work vehicle that travels by driving right and left wheels with a common electric motor. An axle case for accommodating an input shaft, a gear mechanism, a first axle, and a second axle has an input shaft support. An inverter case is mounted on an end surface of the motor case that is fixed to the input shaft support. The inverter case has a base end mounted on the end surface of the motor case and a terminal end which is on the opposite side with respect to the base end. The terminal end protrudes radially outwardly from the outer circumferential surface of the motor case in a direction not facing the first and second axles.
