摘要： Provided is a cooled casing type electric motor, which is cooled by dipping the casing of a stator frame (2) in a coolant. A thermally conductive member layer (15) is formed in a clearance (13) between the back of a stator iron core (1), which is obtained by bringing an electromagnetic steel plate (11) into contact with the inner wall face of the stator frame (2) to fix the plate in the laminated state, and the inner wall face of the stator frame (2). The thermally conductive member layer (15) is made mainly of a graphite sheet, and may be mounted on either the back of the stator iron core (1) or the inner wall face of the stator frame (2). The clearance (13), which might otherwise exist between the back of the stator iron core (1) and the inner wall face of the stator frame (2) so that it would obstruct the radiation of the heat generated in the operation by the stator iron core (1) and transferred to the stator frame (2), thereby to drop the cooling performance of a stator winding (3), can be eliminated to provide the cooled casing type electric motor having an excellent cooling performance.

CONSTITUTION:Metal vapor 10 vaporized toward a different direction from a substrate in a vacuum vessel of the vacuum vapor depositing apparatus, is stuck to the vapor recovering plate 21 and the formed vapor deposited film 13 is heated, melted and recovered. The above vapor recovering plate 21 set symmetrically to right and left directions inclined from a upper part to a diagonal lower part of the substrate is divided into plural small area zones 22 toward a direction with a right angle to the inclining surface. In each zone 22, a heater is independently set and electric source output is periodically varied with control means so as to be possible to control at different temp. By periodically varying the temp. of heater according to recovering time, the temp. distribution in each zone 22 is varied to high temp. low temp. intermediate temp. high temp. Therefore, as the melting zone in the vapor deposited film 13 is shifted to the inclining direction in order, the vapor deposited film 13 stuck to the vapor recovering plate 21 can surely be recovered without detaching and falling down.

摘要： PROBLEM TO BE SOLVED: To provide a motor with high cooling performance by reducing contact thermal resistance between the inner-periphery surface of a cooling jacket and the back surface of a stator iron core. SOLUTION: A rotor 5 and a stator iron core 6 faced each other via a clearance, and the rotor 5 and a stator 4 are covered with a frame 3. A cooling jacket 8 for passing a refrigerant for cooling the stator iron core 6 is formed between the frame 3 and the stator iron core 6. Through a inbt pipe 16 passing through the frame 3, a contact surface between the inner-periphery surface of the cooling jacket 8 and the back surface of the stator iron core 6 is injected with a charging material. Thus a gap is eliminated at the contact surface between the inner-periphery surface of the cooling jacket 8 and the back surface of the stator iron core 6, thereby enhancing heat conduction.

摘要： PROBLEM TO BE SOLVED: To increase rotational torque in a rotating-electric machine and moreover the strength of a rotor is ensured. SOLUTION: A rotor 3 in a rotating-electric machine includes a rotor core 4 with a magnetic pole part 6 as a core part projected outside in a radial direction, and a ring member 5 for covering the outer circumferential part of the rotor core 4. At this time, the projected core parts of the rotor 3 are jointed through the ring member 5, so that the strength of this part against centrifugal force can be ensured even when the thickness of the ring member 5 corresponding to an inter-pole bridge part is made small as compared with the conventional one. Since the ring member 5 is made thin, the quantity of leakage in q-axis magnetic flux into an adjacent inter-pole part through the bridge becomes small and the magnetic resistance of the inter-pole part 7 can be increased to improve the output thereof.
