摘要： The invention provides a synchronous electric motor (10) comprising a rotor (2) with poles, mounted on an axis, separated by an air gap (7) from surrounding poles of a stator (4). The poles of the rotor (2) are magnetised alternately, and on the poles of the stator (4) windings (5) connected in series or in parallel are wound, which magnetise the stator (4) in a direction depending on a direction of current flow in the windings (5) of the stator (4).
The object of the invention is also a power supply system for the electric motor (10) which comprises an AC generator (16) placed on a shaft (12) connected by a control coupling (15) to a shaft (11) on which the rotor (2) of the electric motor (10) is placed. Additionally, in a supply circuit, there is a magnetic amplifier (13) connected in series to the generator (16) and to the motor (10).

摘要： The invention relates to a device for providing a motor that delivers a larger amount of produced energy than the amount required for the operation thereof, eliminating the need for a primary energy supply. The device consists of electromagnets produced with coils of incomplete turns arranged in a stator and permanent magnets arranged in a rotor. When an electric current is applied to the coils of incomplete turns, a force is generated in the magnets, causing the rotor to rotate and generate mechanical energy. The coils of incomplete turns are characterized in that, when the rotor rotates, they allow the magnets of the rotor to pass continuously through said coils.

摘要： Provided is a slim type stator that is used to make a BLDC (Brushless Direct-Current) motor having a stator of a division core structure and a double rotor for use in a drum-washing machine, a slim type motor having the same, and a direct drive apparatus for use in the drum-washing machine. The stator includes: an annular division stator core assembly that is assembled in an annular form by winding a three-phase coil on a number of bobbins that are molded on respective outer circumferences of a number of division cores to thus surround a middle portion of each bobbin wherein each bobbin includes first and second flanges formed at one side of the bobbin and the other side thereof, respectively, and a coupling protrusion and a coupling groove that are formed at both side ends of the first flange that is disposed inward, and wherein the coupling protrusion and the coupling groove are mutually coupled between adjoining division stator bobbins; and a stator holder that molds the division stator core assembly that is formed in an annular form by winding the coils on the bobbins by an insert molding that uses a thermosetting resin, excepting inner and outer side surfaces of each division core of the division stator core assembly.

摘要： An electric machine includes a stator (12) and a coil (18) operable with the stator (12). The rotor (14) includes at least one pole section, the pole section defining a direct axis in a flux barrier having a first end and a second end. Each of the first (60) and second (62) ends are positioned proximate to the stator (12). The first end (60) defines a first angular position relative to the direct axis and the second end (62) defines a second angular position relative to the direct axis. The first angular position is different in magnitude than the second angular position to reduce a torque ripple or torque oscillation of the electric machine.

摘要： A motor case part (30) having a stator (36) and a gear case part (50) having a reduction mechanism (SD) are integrally formed of the same material. In this manner, heat is directly dissipated from the motor case part (30) to the outside without the gear case part (30). Therefore, a brushless wiper motor (20) can be improved in heat radiation performance so as to enhance strength in high temperature can be realized. By manufacturing the motor case part (30) and the gear case part (50) from aluminum, while sufficient radiation performance is secured, a thickness thereof is made thin and lack in rigidity can be overcome. Furthermore, It is unnecessary to manufacture the motor case part (30) and the gear case part (50) individually and it is also unnecessary to perform pressing to a steel plate like the conventional art. Therefore, workability of the motor case part (30) and the gear case part (50) can be improved.
