Description
Technical field
The utility model relates to a kind of novel finite corner motor, belongs to the electrical micro-machine manufacture technology field.
Background technology
On automated machine equipment, adopt a kind of finite corner motor through regular meeting, be used for the signal of telecommunication is transformed into angular displacement.Require this motor that bigger rotating torque will be arranged, response speed is fast, and inertia is little, after the signal of telecommunication stops, can stopping very soon, guarantees accurately location, and it is little, in light weight so that install also to require this motor should have a volume simultaneously.At present, stator or rotor in the common finite corner motor are generally made enamelled wire on ring-shaped core, such structure have only coil half be arranged in air-gap field, winding utilization is lower than 50%.The output torque is little, and the volume of motor is bigger, and weight is also heavier.Owing to adopt the coiling of going in ring, stator inner hole is unsuitable too small, and root diameter is bigger, and inertia is big; Be difficult to realize high output torque, high response speed and high angular acceleration.Therefore existing finite corner motor still can not satisfy the requirement of use.
The utility model content
The purpose of this utility model is, a kind of novel finite corner motor is provided, and can improve the winding utilization of motor, improves the L/D ratio of motor, can make the little leptosomatic motor of volume; And it is big to have output torque, in light weight, and inertia is little, and response speed is fast, and angular acceleration is very high, the characteristics that positioning accuracy is good, thus overcome the deficiencies in the prior art.
The utility model is to constitute like this: comprise stator and be located at the interior rotor of stator, stator comprises housing, is provided with magnetic conductive tube in the housing, and the inwall of magnetic conductive tube is provided with insulating barrier, and insulating barrier is provided with epoxy resin layer, is inlaid with the setting winding in the epoxy resin layer; Rotor comprises the rotor magnetic pole made from high-performance permanent magnet alloy, and the rotor magnetic pole two ends are provided with not magnetic conduction rotating shaft.
In the above-mentioned novel finite corner motor, the rotating shaft of described not magnetic conduction is bearing on the housing through bearing.
In the aforesaid novel finite corner motor, an end of described housing is provided with back-up ring, and an end of housing is provided with packing ring and end cap; Not magnetic conduction rotating shaft in the end cap is provided with spring and pin.
Compared with prior art, prior art can't continue to dwindle the diameter of motor owing to be subjected to the influence of winding construction, so the motor of prior art can only be made the flat motor of little draw ratio, its inertia is relatively large.The utility model is because the iron core in the stator adopts magnetic conductive tube to make; Stator winding adopts the setting winding, uses epoxy encapsulation on the magnetic conductive tube inwall; The rotor of motor adopts the column type magnetic steel material to make, thus can electromotor diameter do very thin, the L/D ratio of motor is increased, can make the little leptosomatic motor of volume.Because it is very little that stator and rotor can be done, so motor is in light weight, diameter diminishes and can reduce inertia, improves response speed, because the positioning accuracy of inertia small size motor also is improved.Because stator winding of the present utility model adopts the setting winding, is fixed on the magnetic conductive tube inwall with epoxy resin; When making machine operation, stator winding levels limit all is in the air-gap field, and winding utilization can reach 100%, effectively raises output torque.The utility model passes through system performance test, motor of the present utility model can be stable in the finite angle scope input electrical signal is converted to output dtc signal on the axle, the motor torque coefficient of variation is no more than 1%, and maximum output angle acceleration can reach 5 * 10
