The principle and effect of this basic scheme lie in:

1. compared with the prior art, the utility model discloses a hold the frame and hold the box with first holding box and second and fix the one side at the motor, first holding box and second hold the box and be used for adorning decoder and driver respectively, need change or overhaul decoder and driver when only need hold the box with first holding box and second and open and take out decoder and driver can, solved current integration PMSM owing to with the driver and the inconvenient driver of the integrated installation of motor and decoder and the problem of change.

Further, permanent magnet synchronous motor body one side symmetry rigid coupling has a plurality of bases, and equal rigid coupling has the double-screw bolt on the base, holds frame circumference equipartition and has a plurality of connecting blocks, all opens the through-hole on the connecting block, and the through-hole is worn out respectively to the double-screw bolt and equal threaded connection has fixation nut. The connecting block on the containing frame is connected with the base on the permanent magnet synchronous motor body by using the fixing nut, so that the containing frame can be easily installed or detached.

Further, the first box that holds and the second holds the box lateral wall rigid coupling and has a plurality of connecting rods, the free end of connecting rod all with hold frame inner wall rigid coupling. A plurality of connecting rods hold the box with first and the second holds the box and fix and hold the frame, and a plurality of connecting rods play the effect of the gravity of sharing decoder and driver, all have the space between a plurality of connecting rods simultaneously, are favorable to the heat dissipation.

Further, one side circumference rigid coupling that PMSM body was equipped with the base has the fixed strip, holds the frame and is close to fixed strip one side rigid coupling and has the card strip, all is equipped with the draw-in groove that can supply card strip card to go into on the fixed strip. The clamping strip card on the containing frame is clamped into the clamping groove, so that the stability of the containing frame on the permanent magnet motor is improved, and the permanent magnet motor body is prevented from shaking.

Furthermore, a plurality of radiating fins are uniformly distributed on the accommodating frame. The heat dissipation can be accelerated to the fin that holds on the frame, and the operation of permanent-magnet machine body is influenced to heat accumulation between permanent-magnet machine body, decoder and the driver.
