Description
Technical field
The present invention relates to a kind of permanent magnet motor magnetic pole mechanical fixed structure, belong to technical field of motors.
Background technology
Advantage such as permagnetic synchronous motor and servo system thereof are little because of its volume, efficient is high and dynamic response characteristic is good is widely used in fields such as industrial drives and SERVO CONTROL.From the electric machine structure form, permagnetic synchronous motor can be divided into inner rotor core and outer-rotor structure two classes.Compare with outer-rotor structure, the permagnetic synchronous motor of inner rotor core has the following advantages:
The winding of inner rotor motor and stator core are installed in the rotor outside, so the cooling surface area of motor is relatively large, the hot property of motor is better; The moment of inertia of inner rotor motor is less relatively, is suitable for the servo system higher to dynamic response requirement; Inner rotor motor rotor surface linear velocity is less relatively, so motor speed can be higher; Inner rotor motor is simple in structure, installs more convenient.
In the inner rotor motor structure, in order to reduce torque fluctuations, usually magnetic pole is bonded in the outer surface of rotor yoke, owing to be subjected to action of centrifugal force, magnetic pole comes off easily in the process of rotor rotation.Adopt at present usually binding strap binding magnetic pole or prevent coming off of magnetic pole in the method that the magnetic pole outer surface is installed protective sleeve; though can protect magnetic pole not to be subjected to the influence of centrifugal force like this and come off; but installation process complexity; be not suitable for producing in batches, and can't stop magnetic pole to be subjected to tangential stress to act on the slip of circumferencial direction effectively.
Less than 1 magneto,, there is certain space each other for pole embrace,, can has the insecure problem of installing and locating if it is directly installed on the rotor yoke because each magnetic pole is not close to.The solution that adopts is magnetic pole positioning sleeve of additional designs at present, though can satisfy the requirement of magnetic pole positioning accuracy like this, installation process is extremely loaded down with trivial details time-consuming, makes electric machine structure complexity and processing time consuming simultaneously.
Summary of the invention
The rotor magnetic pole that the objective of the invention is to solve the internal rotor permanent-magnetic synchronous machine is located insecure problem, and a kind of permanent magnet motor magnetic pole mechanical fixed structure is provided.
The present invention includes rotating shaft and rotor yoke, rotor yoke is socketed on the outer round surface of rotating shaft, and it also comprises two annular rotor pressing plates and P magnetic pole,
Two annular rotor pressing plates are fixedly connected on the two ends of rotor yoke respectively, and form groove with the outer surface of rotor yoke, and P magnetic pole is evenly distributed in the described groove along the rotor circumference direction,
The outer ring surface of described each annular rotor pressing plate dashes respectively has P spacer pin and P to protruding pin, P spacer pin is evenly distributed on the excircle of annular rotor pressing plate, P spacer pin on two annular rotor pressing plates is oppositely arranged, axially relative a pair of spacer pin and closely contacts with described magnetic pole between adjacent two magnetic poles;
The bilateral symmetry of each spacer pin a pair of protruding pin that distributes, this forms the V font to protruding pin, and described protruding pin is used to press solidly the end of the magnetic pole that is adjacent.
Advantage of the present invention is: it is unreliable that the present invention can effectively solve the rotor magnetic pole location of internal rotor permanent-magnetic synchronous machine, and the problem of complex installation process.It is by being provided with the mode of spacer pin and protruding pin, the shallow storage space of magnetic pole on rotor yoke is separated out, guaranteed magnetic pole fixedly laying on rotor yoke thus, make the installing and locating precision of magnetic pole accurate, the rotor magnetic pole that has solved the internal rotor permanent-magnetic synchronous machine effectively comes off owing to being subjected to centrifugal action in running, or owing to be subjected to the tangential force effect and problem of slip, the present invention simultaneously is simple in structure, easy to implement, can reduce the installation difficulty of magnetic pole to a certain extent, and then the effective working (machining) efficiency that improves motor of meeting, be easy in servo field, apply.
