Abstract
The apparatus includes a laminated core that has frontal end faces and slots with a winding extending in the slots. An electrical insulating end plate is provided adjacent at each frontal end face and adjacent to the winding heads of the winding. At least one of the end plates has a connecting box with a plurality of clamps for the ends of the windings and the terminal of a motor protection device.
Claims14
An electrical machine, comprising a laminated core having winding slots and frontal faces, at least one winding extending at least in part in said slots and having winding heads and winding ends, electrical connecting wires having ends, each winding end being of an elongated length, an electrically insulating end plate adjacent to each core frontal face and a winding head, and a connecting box joined to one of the end plates and having the electrical connecting wires and winding ends extended therein, the connecting box having a clamp for each winding end to receive the respective end after the introduction of the winding end into the connecting box, each clamp having insulation-piercing contacts, the insulation-piercing contacts comprising two cutting edges that converge with increasing depth for contacting the winding end.
An electrical machine, comprising a laminated core having winding slots and frontal faces, a winding extending at least in part in said slots and having winding heads and winding ends, electrical connecting wires having ends, an electrically insulating end plate adjacent to each core frontal face and a winding head, a connecting box integrally joined to the end plate and having the electrical connecting wires and the winding end extended therein, a motor protection device between box and one of the winding and the laminated core and having a terminal, the connecting box having a first clamp for engaging the winding end and a second clamp for the motor protection device terminal, a retaining arm for holding the motor protection device against at least one of the winding and the laminated core, said retaining arm extending into the connecting box, and a short circuiting link providing a short circuit between the first and second clamps, the short circuiting link being connected to the retaining arm.
