摘要： The invention relates to a rotor for an electric motor, particularly an electric line-start motor, comprising axially accommodating spaces (4 to 6) for conductor rods, and axially extending receiving spaces (10, 11) for permanent magnets (14, 15), which are-designed and located in such a way that they generate a permanent magnet field with a magnet axis (22) and a neutral axis (23). The aim of the invention is to ensure that the rotor runs as regularly as possible during the operation of the electric motor. To this end, the diameter of the rotor along the magnet axis is larger than that along the neutral axis (23).

摘要： The invention provides an electrical line-start motor comprising with a stator and a squirrel cage rotor adapted for rotation around a centre axis. The rotor comprises a squirrel cage winding in which a current is induced by corresponding windings of the stator, and a set of permanent magnets. To protect the magnets from excessive heat, the rotor comprises thermal barriers e.g. in the form of cavities located between the squirrel cage winding of the rotor and the magnets. Due to the thermal barriers, the thermal conductivity in a path between the windings and the magnets are reduced and the magnets are protected.

摘要： The invention provides a method of making a squirrel cage rotor for an electrical motor, and to a rotor for such a motor. The rotor comprises a rotor stack of a magnetically conductive material and a squirrel cage of an electrically conductive material. At least one of the short circuit rings are made by compression and sintering of a powder in which a solid element is embedded. The solid element facilitates manufacturing by increasing strength of potentially weak areas of the rotor, e.g. around openings into the shaft bore, rotor slots etc.

摘要： The invention provides a rotor for an electrical motor, a tool for making a rotor core and a method of making the rotor. The rotor could be incorporated e.g. in a line-start motor and comprises a squirrel cage and magnet located in a rotor core. The magnets are, in one end of the rotor, secured by an end plate with apertures which are larger than the magnet openings, and the end plate is indexed relative to the magnet slots such that a first portion of openings into the magnet slots is in communication with the aperture and such that a remaining, second, portion of the magnet slots is covered by the end plate. In one aspect, the end plate forms an integrated part of the rotor core and comprises openings cooperating with conductor slots to form through-going passages for conductors of the squirrel cage. In that way, the end plate is held in a completely fixed position by the squirrel cage which is moulded directly onto the core and into the conductor slots.

摘要： The invention provides a rotor for an electrical motor, e.g. a line-start motor. The rotor comprises a magnet located in a cavity in a rotor core. The core is laminated from sheets of magnetically conductive material and the magnet is secured in the cavity by an end plate which covers the end face. To avoid short circuiting of the magnet, an aperture is provided in the end plate such that a first portion of the opening into the cavity is in communication with the aperture and such that a remaining, second, portion of the cavity is covered by the end plate to secure the magnet in the cavity independently upon the orientation of the end plate around the center axis.
