Description
Technical field
This utility model relates to motor technology field, particularly relates to a kind of threephase asynchronous.
Background technology
Make the threephase asynchronous machine of motor running. The rotating speed of three-phase asynchronous motor rotor is lower than the rotating speed of rotating excitation field, and rotor windings produces electromotive force and electric current because there is relative motion between magnetic field, and produces electromagnetic torque with magnetic field interaction, it is achieved energy conversion.
Compared with monopole asynchronous motor, threephase asynchronous runnability is good, and can save various material. By the difference of rotor structure, threephase asynchronous can be divided into cage and Wound-rotor type two kinds. The Induction Motor Structure of cage rotor is simple, reliable, lightweight, low price, is widely used, and it major downside is that speed governing difficulty. The rotor of wound three-phase asynchronous motor is the same with stator to be also provided with three-phase windings and is connected with outside rheostat by slip ring, brush. Standardsizing rheostat resistance can improve the startability of motor and regulate the rotating speed of motor.
In prior art, motor is in long playing process, it is easy to be heated, cause inside electric wire be burned out so that whole motor is scrapped, thus design a kind of improve heat radiation one after another threephase asynchronous very urgent.
Summary of the invention
In view of this, it is necessary to a kind of threephase asynchronous improving heat radiation one after another is provided.
This utility model is realized in, a kind of threephase asynchronous, including motor casing, also include metal cap, cooling dome, cooler, water pump and baffle plate, it is peripheral that described metal cap is wrapped in described motor casing, and there is between metal cap and motor casing certain gap, form the cooling chamber sealed, described cooling dome is arranged on the outer wall of described metal cap, seal between cooling dome and described metal cap and install, described baffle plate is fixed on the outer wall of motor casing, and extend in the inner chamber of cooling dome, the inner chamber of described cooling dome is become the first annular seal space and the second annular seal space by described barrier partitions, described first annular seal space connection is in the cooling chamber on the left of described baffle plate, described second annular seal space connection is in the cooling chamber on the right side of described baffle plate, it is interconnected between first annular seal space and the second annular seal space, described cooler and water pump are each attached on the outer wall of described cooling dome, and cooler is in the first annular seal space, water pump is in the second annular seal space, described cooling chamber, aqueous solution it is full of in first annular seal space and the second annular seal space.
Further, the water inlet on described water pump connects with described second annular seal space, and outlet connects described cooling chamber.
The advantage of a kind of threephase asynchronous that this utility model provides is in that: this utility model is rational in infrastructure simply, during use, starting mode of pump, aqueous solution inside is pumped in the cooling chamber on the left of baffle plate, water detours in the cooling chamber entered on the right side of baffle plate for a week along motor casing, in the process detoured, aqueous solution absorbs the heat in motor, enter in the first annular seal space, in the first annular seal space, aqueous solution is carried out cooling process by cooler, it is again introduced in the second annular seal space, it is pumped in the cooling chamber on the left of baffle plate again through water pump, so move in circles, substantially increase the cooling effectiveness of motor, and environmental protection, make motor in long playing process, not easily damaged burn, economize on resources very cost, and extend the service life of motor.
