An electric machine having a rotor with a ventilation port and a rotor coupling with at least one air disturber.

The present invention provides a driving unit for an analog meter. The size of the driving unit is modified into a column shape, so that the first tape and second tape of the stator unit can be placed in double layers, guiding more pins of the input terminal from the same side. The driving unit can simplify the manufacturing process, and the size of the components of the driving unit are greatly reduced, making assembly more flexible or emptying more space for other components. The more concentr...

A modular permanent-magnet electric motor assembly having a predetermined maximum power output for a submersible pump assembly, a stator having a plurality of electric coils adapted to be energized to create a magnetic field, and a rotor assembly disposed about a rotor shaft. The rotor assembly comprises a predetermined number of rotor modules sufficient to achieve the predetermined power output and a pair of bearing carriers separated by the rotor modules. Each rotor module comprises a rotor co...

A rotor core is provided with a pole piece portion holding a magnet and a balance weight portion, wherein said hub fitting hole is inserted a metal hub having a tapered axis hole and part fitting portion so as to be fixed each other, and said rotor core is coated with synthetic resins, thereby the use of metal can be limited only to parts where mechanical strength is required so that the whole rotor weight can be reduced and can be assembled easily, and be allow various parts can be fitted stabl...

Highly selective and high yield process for producing antitumor agent 1-phthalidyl-5-fluorouracil derivatives of formula (I) which comprises reacting a phthalidyl compound (II) with an amine (III) to yield the quaternary ammonium salts (IV), and reacting the latter with 5-fluorouracil. ##STR1## [wherein X is leaving group; ##STR2## is triethylamine, N-methylmorpholine, N-ethylmorpholine, and the like; R.sup.4 and R.sup.5 each is hydrogen, trialkylsilyloxy, alkoxy, nitro, cyano, carboxy, or alkox...

A permanent-magnet generator is provided that has a bowl-shaped fly wheel integrally formed with a boss part by casting or hot forging, that reduces rotational imbalance and the quantity of balance correction processing such as drilling. The permanent-magnet generator has a bowl-shaped fly wheel produced by casting or hot forging, having a circumferential wall part and a bottom wall part, and having a boss part for supporting a rotating shaft, the boss part being integrally formed at the center ...

A frequency transmitter for producing signals to control the brake force at the wheels of motor vehicles, which includes a rotating toothed arrangement secured at the circumference of each output shaft of the differential gear cooperating with a stationary tooth arrangement disposed in an insert member arranged in the bearing cover of the differential gear between the tapered roller bearing assembly for the axle drive bevel wheel or the differential gear housing and a retaining ring providing an...

The present invention is a methodology for assembling a magnet onto a rotor for an energy storage apparatus. The methodology includes the step of mounting a magnet onto a mandrel. The methodology also includes the step of turning an outer diameter of the magnet to a predetermined size. The methodology further includes the step of turning a rim section of the rotor for receiving the magnet to a predetermined size. The methodology still further includes the step of attaching the magnet to the rim ...

The invention relates to a plug connector arrangement with a two-part mating halves (1, 29), in which a first mating half (1) can be joined to a second mating half (29) via a plug-in control (7). The plug-in control (7) has a lever arm (2) pivotally mounted on a mating half (1) that controls a gearing region (9, 36, 37), forcibly actuating the mating halves (1, 29). The lever arm (2) is provided on one side on the mating half (1) and in addition to its pivot movement (8) is mounted via a pivot s...

The transducer includes a permanent magnet with opposite poles on a pair of opposite face surfaces thereof, a pair of inductive coil assemblies operatively positioned with corresponding ends thereof adjacent one of the magnet poles, a rotatable magnetic disc with a plurality of uniformly spaced teeth thereon, and elongate pole pieces operatively engaging the remaining pole of the magnet and the other ends of the coil assemblies. The pole pieces are positioned in opposed relation with the magneti...
