Description
Technical field
The utility model relates to a kind of stator of motor, particularly relates to a kind of torque motor stator.
Background technology
Traditional motor stator punching adopts the silicon steel sheet of annular, adds and adopts the full circle punching out man-hour, and the silicon steel sheet waste is seriously during the stator punching punching molding like this.Because torque motor mostly is greatly permagnetic synchronous motor, thereby has cogging torque, this can cause torque pulsation, in addition, and when torque motor is operated in defectives such as going back the ubiquity poor heat radiation under the slow-speed of revolution, the large torque operating mode.
Summary of the invention
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, provides a kind of and can not only greatly save raw material, and work as machine operation under the slow-speed of revolution, large torque operating mode, has the torque motor stator sector piece of excellent heat dispersion performance.
For solving the problems of the technologies described above, the utility model adopts a kind of like this torque motor stator sector piece, comprise the fanning strip body, exterior arc surface at described fanning strip body is provided with some the mounting bar slots that are used for inserting mounting bar, be provided with some the coil slots that are used for inserting motor coil at the inner arc surface of described fanning strip body, be provided with some the coolant pipe slots that are used for inserting coolant pipe at the end face of described fanning strip body.
As a kind of preferred implementation of the present utility model, described mounting bar slot is evenly distributed on the exterior arc surface of described fanning strip body, and the cross section of described mounting bar slot is inverted T-shape.
In the utility model, the upper opening width of described inverted T-shape mounting bar slot and the ratio of lower openings width are preferably 7 ︰ 11.
In the utility model, described coil slot is evenly distributed on the inner arc surface of described fanning strip body, and the width of rebate of described coil slot opening part is 7.3mm.
In the utility model, the cross section semicircular in shape of described coolant pipe slot, and the coolant pipe slot is connected with described coil slot.
After adopting said structure, the utlity model has following beneficial effect:
Because stator punching of the present utility model adopts fanning strip, thereby has greatly saved raw material.
Because the exterior arc surface at the fanning strip body is provided with some the mounting bar slots that are used for inserting mounting bar, the cross section of described mounting bar slot preferably is inverted T-shape, can will insert mounting bar behind some fanning strip closed assemblies like this, only need to be screwed at the mounting bar two ends nut can be fixed into the fanning strip of closed assembly the fanning strip group, thereby has saved welding sequence.
Because the end face at the fanning strip body is provided with some the coolant pipe slots that are used for inserting coolant pipe, the preferred semicircular in shape of the cross section of described coolant pipe slot, and the coolant pipe slot is connected with described coil slot, so when mounted, coolant pipe can be packed into by in the strip coolant pipe slot that forms behind some fanning strip closed assemblies, coolant pipe is with after the external refrigeration device is connected, passing into cooling fluid in coolant pipe can take the heat that motor internal produces out of, thereby has greatly improved the heat-sinking capability of motor.
Because the width of rebate of coil slot opening part of the present utility model is preferably 7.3mm, can effectively weaken cogging torque like this, reduce the motor output torque pulsation.
