Abstract
The invention discloses a permanent magnet motor which comprises a shell, a stator, a rotor, a front end cover, a rear end cover, a bearing end cover, cooling fins and a condenser. The stator and the rotor are installed in the shell. The front end and the rear end of the shell are provided with the front end cover and the rear end cover respectively. A bearing is arranged in the front end cover and the rear end cover, the outer side of the bearing is provided with the bearing end cover, and the cooling fins are installed in the stator and the shell. The cooling fins are communicated with the external condenser, and an oil sealing groove is formed among the bearing end cover, the front end cover and the rear end cover. According to the permanent magnet motor, the cooling fins are installed on the stator and the shell, the cooling fins are connected with the condenser, circulation cooling of the motor is achieved, and due to the oil sealing groove among the front end cover, the rear end cover and the bearing end cover, the dustproof effect is greatly improved.
Description
Technical field
The invention belongs to machine field, relate in particular to a kind of magneto.
Background technology
Present stage, the type of cooling of high-power permanent magnet motor is water-cooled and natural air cooled, but water-cooling pattern security reliability is low, be eliminated gradually, and although air cooling way can play the cooling effect when low temperature, but when the motor short time, temperature rise was too high, air-cooledly do not have a rapidly cooling effect, heat build-up is in motor, very easily to magneto, bring the harm such as loss of excitation, and magneto in use has higher requirement to surrounding environment, if particularly the dust particle in environment enters magneto inside in a large number, tend to cause equipment fault.
Summary of the invention
The object of the present invention is to provide a kind of magneto, be intended to solve existing magneto cooling effect and the bad problem of dust-proof effect.
The present invention is achieved in that a kind of magneto comprises housing, stator, rotor, front end housing, rear end cap, bearing (ball) cover, cooling fin, condenser; Described stator and rotor are arranged on enclosure interior, housing front-end and back-end are separately installed with front end housing and rear end cap, bearing is arranged in front end housing and rear end cap, bearing (ball) cover is installed in bearing outside, cooling fin is arranged on stator and enclosure interior, cooling fin is communicated with outside condenser, is provided with oil seal groove between bearing (ball) cover and front end housing and rear end cap.
Further, described cooling fin comprises that arc is on chip and cylindric, and arc-shaped flaky cooling fin is arranged on stator, and cylindric cooling fin is arranged on housing.
Further, described stator arranged outside has the cooling fin mounting groove consistent with arc-shaped flaky cooling fin structure.
Further, on the fin of described hull outside, be provided with the through hole that cooling fin is installed.
Further, described front end housing and the oil seal groove on rear end cap are the seal groove with spacing convave trough of annular, are provided with the space protrusion matching with spacing convave trough on bearing (ball) cover.
effect gathers
Magneto of the present invention by installing cooling fin on stator and housing, and cooling fin is connected with condenser, realizes the circulating cooling to motor, and the oil seal groove by between front end housing, rear end cap and bearing (ball) cover, has improved dust-proof effect greatly.
