A mover driving shaft is provided with a rare earth permanent magnet. A stator is a three-phase winding, and the stator winding is connected with a three-phase output end of a frequency governor, can vibrate at a range of 0.2 Hz to 400 Hz, and control the vibration displacement and the exciting force of the motor via the frequency governor by information provided by a displacement sensor and a pressure sensor. The three-phase vibrating motor can be directly connected with a three-phase motive power supply to form a mechanical vibration power source of 50 Hz.

Description
The utility model is a kind of motor that AC energy is converted to vibration mechanical energy.
This motor belongs to the moving-magnetic type vibrating motor, fixing permanent-magnet steel on driving shaft, the alternating current by certain frequency in the coil of stator winding, promptly produce alternating magnetic fields, interact with permanent-magnet steel, on driving shaft, produce the electromagnetic force of an alternation, make the driving shaft double vibrations." oscillating motor " chapter 5 of Beijing Publishing House's publication in 1991 has been introduced the moving-magnetic type vibrating motor.On the driving shaft of motor, fix a permanent-magnet steel, stator winding is one group of single phase winding, provide the blow-up time-dependent current as power supply by power amplifier, the maximum displacement and the exciting force of vibrating motor are controlled by displacement transducer and power transducer and test macro thereof, control system.This cover power supply and control system cost are higher, are not suitable for making the above powerful motor of 10KW, more can not directly connect the three-phase electrical source of power and constitute powerful 50Hz vibrating motor.
The purpose of this utility model provides a kind of moving-magnetic type vibrating motor with three phase windings, making it can be that power supply and control system constitute the three-phase vibratory motor systems with the variable-frequency governor, perhaps directly connects the vibrating motor that the three-phase electrical source of power constitutes 50Hz.
The purpose of this utility model is achieved in that installs three blocks of permanent-magnet steels on the driving shaft of motor, at the stator position of every block of permanent-magnet steel a winding coil is arranged, totally three windings, the input of one of them stator winding and output, reverse with the input/output terminal of other two winding coils, make 60 ℃ of electromagnetic force that this phase winding produces and other two-phase inequality, the stack of three-phase electricity magnetic force just produces the axial alternating electromagnetic force that peak value is two times of single-phase actuating forces on driving shaft, make the frequency double vibrations of driving shaft by power supply.
The utility model is because adopted the threephase stator winding, so it is easy to connect to form a complete three-phase moving-magnetic type vibratory motor systems with three-phase output end of variable-frequency governor, its vibration frequency can be controlled the maximum displacement and the vibration force of vibration by variable-frequency governor simultaneously from changing between the 0.2Hz to 400Hz.Because variable-frequency governor development at present is quite ripe, commercial degree height, thus the utlity model has the reliability height, easy to operate, be convenient to control, the characteristics that price is low also are convenient to make the above powerful vibrating motor of 10KW.As only needing the vibration of 50Hz, as long as this motor directly is connected with the three-phase electrical source of power, and can control its amplitude and exciting force by adjustable transformer, system is simpler, and cost is lower.
The concrete structure of utility model is provided by following embodiment and accompanying drawing.
Native system is dimeric, i.e. motor body and variable-frequency governor.
Motor body comprises with the lower part, be driving shaft (8), on driving shaft, fix three blocks of permanent-magnet steels (13), (14), (15), driving shaft is by first group of coil (5), (7), second group of coil (3), (4) are supported in two springs (11), (16) up and down, the 3rd group of coil (1), (2), wherein have one group of coil and other two groups reverse, be made as first group of coil in the present embodiment, (6), (12) are iron cores.When three-phase alternating current passes through three groups of coils of motor, every group of magnetic field that coil produced will produce the sinusoidal alternating electromagnetic force with its permanent-magnet steel, phase difference between the three-phase current is 120 ℃, because the phase place of first group coil has been fallen 180 ℃, therefore the electromagnetic force of the leading second group of coil of electromagnetic force of first group of coil is 60 ℃, lag behind 60 ℃ of the 3rd group of coils, the electromagnetic force of such three coils making a concerted effort on driving shaft is a sinusoidal alternating power, its peak value is two times of one group of electromagnetic force wherein, and driving shaft vibrates with the frequency of power supply.
Variable-frequency governor (17) is converted to the electric energy of three-phase 50Hz power supply (18) three-phase alternating current of the required frequency of motor, supply with vibrating motor, and, control the size of the maximum displacement of the size of vibration force of motor and vibration by the signal that power transducer (9) and displacement transducer (10) are provided.
