Abstract
The utility model relates to a wound stator for a servo motor, which achieves simple structure and lower cost. The wound stator for the servo motor comprises a stator shell, a plurality of stator cores and a plurality of coils, wherein the stator cores are respectively fixed at intervals in an inner circle of the stator shell to form a tooth shape, the coils are respectively arranged in the intervals to surround the stator cores, and the spaces around the coils are filled with epoxy. The spaces around the coils as well as the gaps between the coils and the stator shell are filled with the epoxy so that the structure of the wound stator for the servo motor can be simplified by utilizing the good thermal conductivity of the epoxy, thereby reducing the production cost.
Description
Technical field
The utility model relates to field of motor manufacturing, and in particular, the utility model is about improving a kind of servomotor wire-wound stator of servomotor heat radiation.
Background technology
At present, the servomotor extensive use is to the also raising day by day of requirement of servomotor.As requiring high-power, high-revolving servomotor, its volume but will reduce; Concerning the servomotor wound stator, cause the heat radiation difficulty of stator.
Patent Office of the People's Republic of China has announced a CN201466881U document on May 12nd, 2010, name is called the alternating current impression servomotor, this servomotor comprises electric machine main shaft, rotor, front end housing, rear end cap and stator core, front end housing and rear end cap are installed in the two ends of stator core respectively, rotor is rotatable to be sleeved in the stator core, electric machine main shaft is fixedly set in the rotor, and the two ends of electric machine main shaft are sleeved on front end housing and the rear end cap by bearing is rotatable respectively; Described stator core outer surface is provided with at least one groove radiator structure that extends vertically.The shortcoming of this servomotor is a complex structure, causes manufacturing cost bigger.
Summary of the invention
The utility model makes the stator structure complexity cause the bigger problem of manufacturing cost for solving the servomotor wound stator heat radiation difficulty that exists in the prior art, provides a kind of simple in structure, lower-cost servomotor wire-wound stator.
The technical scheme that its technical problem that solves the utility model adopts is: the utility model comprises stator case, some stator cores, some coils, stator core fixed interval respectively forms dentation at the inner ring of stator case, in coil is separately positioned at interval and around stator core, around coil, be full of epoxy.Epoxy have good thermal conductivity, electric insulating quality, very low shrinkage and weather resisteant and solidify after machinability; Epoxy fully infiltrates the slit in the coil; good insulation performance protective effect and thermolysis have been played; make the motor product noise after finishing reduce, improved degree of protection, under high temperature, salt fog, mould, corrosive gas and conductivity dust atmosphere, coil is played a protective role.
As preferably, epoxy also is full of the space between coil and stator case.Epoxy directly contacts with stator case, utilize the good thermal conductivity of epoxy directly to pass on the stator case heat of the enamelled wire in the stator, improved the heat dispersion of motor, also just improved the output torque of motor, the output torque of process testing of electric motors can improve 10%-20%.
As preferably, stator case and stator core are connected as a single entity.Stator case and stator core are made one can further increase radiating effect.
As preferably, stator core is a T shape.Stator core is designed to T shape can reduces magnetic gap between stator core and rotor, reduce magnetic loss, thereby reduce the caloric value of stator.
The beneficial effects of the utility model are: being full of epoxy around the coil and in the gap of coil and stator case, utilize the thermal conductive resin of epoxy, the wire-wound stator structure of servomotor is simplified, reduced manufacturing cost.
