Abstract
The utility model relates to a high- efficiency permanent-magnetic frequency-variable speed-regulating three-phase synchronous motor, comprising a casing mounted on a pedestal. A front end cover and a rear end cover are respectively arranged at the front end and the rear end of the casing, and are respectively equipped with a first bearing oil-filling hole and a second bearing oil-filling hole; and a motor shaft is installed in the casing, and a rotor is installed on the motor shaft. The motor is characterized in that multiple grooves whose end surface is of a bending shape are arranged in the rotor along the axial direction of the rotor, and are uniformly distributed along the circumferential direction of the end surface of the rotor; a permanent magnet is arranged in each groove; a hanging ring is arranged in the upper of the casing, and a conjunction box is arranged on a casing body of the casing; and foot holes are arranged in the pedestal. The motor has the advantages that the rotor adopts the permanent magnets, and the magnetic field strength is strong, therefore, the starting torque is large, the starting current is small and the speed adjustment range is wide; and neither the copper loss nor the iron loss exists on the motor rotor, so that the efficiency of the motor is higher than the efficiency of the frequency-variable motor with identical capacity.
Description
Technical field
The utility model relates to a kind of motor, especially a kind of high-efficiency permanent magnetism variable-frequency control three-phase synchronous motor.
Background technology
The Nd-Fe-Bo permanent magnet material that come out the eighties in last century causes the extensive concern of domestic and international academia with its superior magnetic property.Compare with traditional asynchronous machine, adopt neodymium iron boron as the permagnetic synchronous motor of excitation source, its efficient, power factor (PF) all improve a lot, and energy-saving effect is fairly obvious, is a kind of up-and-coming energy-efficient product.At the nineties initial stage in last century, China has successfully developed permanent magnetic material, originally because the factor of the each side such as technology, the first generation of exploitation, second generation permanent magnet product are because its magnetic property is relatively poor, maximum magnetic energy product (BH) is quite low, therefore the exploitation that is used for motor product only is confined to micromachine or control machine field, and is but a dream for the exploitation of large-scale magneto.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of high-efficiency permanent magnetism variable-frequency control three-phase synchronous motor is provided, have copper loss and iron loss to solve existing synchronous machine, and existing synchronous machine efficient ratio is with the low problem of capacity adjustable frequency motor.
The technical scheme that provides according to the utility model, a kind of high-efficiency permanent magnetism variable-frequency control three-phase synchronous motor, comprise the casing that is installed on the base, the forward and backward two ends of casing arrange respectively front end housing and rear end cap, are respectively equipped with clutch shaft bearing tank filler sleeve and the second bearing oiling hole at front end housing and rear end cap; The mounted motor axle is installed rotor at motor shaft in described casing; Feature is: the axis direction in the inside of described rotor along rotor arranges the cell body that a plurality of end faces are bending, and cell body evenly distributes along the circumferencial direction of rotor end-face, and permanent magnet is set respectively in each cell body.
Top at described casing is provided with suspension ring, is provided with terminal box at the housing of casing.
Be provided with the footing hole at described base.
The beneficial effects of the utility model are: motor rotor described in the utility model adopts permanent magnet, and magnetic field intensity is large, so its detent torque is large, starting current is little, speed-regulating range width; Not only without copper loss but also without iron loss, its efficient is than high with the capacity adjustable frequency motor on the rotor described in the utility model.
