Description
Technical Field
The invention relates to the technical field of magnetic coupling transmission, in particular to a hybrid excitation eddy current speed regulation device.
Background
The traditional mechanical transmission structure mainly comprises a gear structure, a belt pulley mechanism, a chain structure, a worm gear and worm, and the like, and the transmission mechanisms are directly and rigidly connected with a load, so that friction wear, vibration, noise and the like exist in the transmission process. The research and application of the magnetic coupler have wide space and value. For example, a permanent magnet eddy current governor is a non-contact type speed regulating device developed based on the principle of electromagnetic induction, and mainly functions to realize the motion and power transmission between a motor driving shaft and a load output shaft in a motion system. The working principle is that when the input shaft drives the permanent magnet disc to rotate, the input shaft and the output shaft form a rotation speed difference, the copper disc cuts a magnetic induction line sent by a permanent magnet in the permanent magnet disc to generate induced electromotive force and generate eddy current in the copper disc, the eddy current generates a counter-induction magnetic field, the counter-induction magnetic field interacts with a magnetic field generated by the permanent magnet, so that torque transmission between the copper disc and the copper disc is realized, the output shaft is driven to rotate, and the rotation speed and the torque of the output shaft are controlled by changing the size of an air gap between the copper disc and the permanent magnet. Another application of permanent magnet drive technology is the electrically excited eddy current drive, which uses magnetic material, which is a feature of the device. The hysteresis material is distinguished from the permanent magnet material in that the former is easily changed in polarity, so that torque is easily adjusted, providing excellent workability, and is widely used at present. But its rated torque is small because at rated torque, the clutch begins to slip, the hysteresis material absorbs energy from the system, and the kinetic energy becomes heat due to the change of magnetic poles, and this part of heat should be dissipated and cooled in time. The torque regulation control of the electrically excited eddy current transmission is provided by the field coil, requires a dc power supply and a control system, which is the best choice in an automatic control system. The integration of the magnetic device with the sensor and microprocessor may be automated for certain processes. For example, when the diameter of the winding machine is increased, the torque is changed correspondingly by controlling the change of the exciting current, so as to ensure that constant tension is obtained.
The permanent magnet transmission has no excitation consumption, but the air gap is adjusted by a mechanical mode or a servo mechanism, so that the use and the operation are inconvenient. The electric excitation transmission is convenient to adjust, but the electric excitation power consumption is large. In addition, most of the traditional permanent magnetic transmission adopts a claw type structure or a disc type structure, although the speed regulation can be realized, the speed regulation efficiency is low, the speed regulation range is small, the speed regulation is not stable enough and the like,
