Abstract
The utility model relates to a motor design technical field, concretely relates to closed loop motion type control permanent-magnet machine rotor punching aims at solving among the prior art low-speed torque fluctuation big, leads to the problem that control stability is low, control response is slow, and its technical essential lies in: including towards the piece iron core, be provided with a plurality of groups along the magnet steel groove of circumference array towards on the piece iron core, every group the magnet steel groove is provided with two respectively, two with the group the magnet steel groove is the V type setting to the directional periphery edge towards the piece iron core of V type opening, each the magnet steel groove with be provided with the round hole towards between the piece iron core neighboring. Through setting up multiunit magnetic steel groove and round hole for under the intensity condition that does not influence the towards piece structure, reduced the torque ripple of motor effectively, and improved the control stability and the response speed of motor.
Description
Technical Field
The utility model relates to a motor design technical field, concretely relates to closed loop motion type control permanent-magnet machine rotor punching.
Background
The motor is an electromagnetic device which realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. The electric motor is also known (colloquially called motor) and is indicated in the circuit by the letter "M" (old standard is indicated by "D"). Its main function is to generate driving torque as power source of electric appliance or various machines. The existing motor devices are various, the technology of the existing direct current or alternating current motor is mature, and the principle is that the rotor rotates and does work through magnetic induction. The permanent magnet motor is a new motor, and has the advantages of small volume, low energy consumption, easy control and the like, so the permanent magnet motor is gradually widely applied.
The original permanent magnet motor can cause certain torque pulsation when running at low speed due to the torque fluctuation characteristic, and the control stability is low and the control response is slow when the motor is used as a motion type control application.
SUMMERY OF THE UTILITY MODEL
Therefore, the to-be-solved technical problem of the utility model lies in overcoming the low-speed torque fluctuation in the prior art big, leads to the low, slow defect of control response of control stability to a closed loop motion type control permanent-magnet machine rotor punching is provided.
The above technical purpose of the present invention can be achieved by the following technical solutions:
the utility model provides a closed loop motion type control permanent-magnet machine rotor punching, includes towards the piece iron core, be provided with a plurality of groups along the magnet steel groove of circumference array towards the piece iron core, every group the magnet steel groove is provided with two respectively, two with the group the magnet steel groove is the V type setting to the directional periphery edge towards the piece iron core of V type opening, each the magnet steel groove with be provided with the round hole towards between the piece iron core neighboring.
In some embodiments of the present application, the diameter of the circular hole is 5mm, and the distance between the circular hole and the rotor outer wall and between the magnetic steel grooves is 1.5mm, respectively.
In some embodiments of the present application, eight sets of magnetic steel slots are provided, and the sharp angle of the V-shaped on the magnetic steel slot points to the circle center of the stamped iron core.
The application provides a closed loop motion type control permanent-magnet machine rotor punching for under the intensity condition that does not influence the structure of punching, the torque ripple of motor has been reduced effectively through setting up multiunit magnetic steel groove and round hole, and the control stability and the response speed of motor have been improved.
