- the control circuit 570 detects the zero crossing point (ZCP) of the counter electromotive force according to the terminal voltage of each phase (U, V, W) detected by the terminal voltage detector 560 to obtain position information of the rotor.
- ZCP zero crossing point
- the control circuit 570 performs an overall inverter 530 control algorithm.
- the PWM signal generator 580 generates a pattern of the PWM signal by the output of the control circuit 570 and supplies it to the inverter 530.
- FIG. 14 is a graph showing a controller output signal and a motor voltage application for operating the rotor clockwise and counterclockwise in the present invention.
- the control objective of the rotor position detection in the Schmish motor 400 of the present invention is an ideal control without torque ripple, and for this purpose, both the voltage and the current may be a sine wave.
- an initial driving algorithm is required because the magnet position of the rotor is not known at any initial stage, and in this case, the induction electromotive force is obtained because the rotor starts to rotate once.
- a separate initial run algorithm is required.
- This initial driving algorithm is a known technique that is already used in all of the BCD motor 400 control, and in this case also uses a well-known forced alignment method is omitted in detail.
- the induced electromotive force is generated by synchronously rotating the rotor in a predetermined order until the rotation frequency reaches a constant speed. From this section, sine wave control is entered.
- the driving method generally uses the same PWM control method as the sinusoidal control method of the AC induction motor.
- the carrier frequency may be applied to various methods such as triangular wave, sawtooth wave method or perspective method.
- a zero crossing point (ZCP) through which the induced electromotive force of each phase obtained by the rotation of the rotor passes through the zero cross is detected, and the phase is switched based on the zero crossing point (ZCP) information to output a PWM driving signal.
- ZCP zero crossing point
- the current waveform has a sinusoidal waveform since it is driven by three-phase energization.
- the brush for washing the face 600 is vibrated while programming the control circuit to rotate the brushless electric motor 400 forward and reverse.
- the rotor of the brush lead electric motor 400 rotates by a predetermined angle, and then checks the position by using induced electromotive force, and then rotates the rotor reversely, and rotates the rotor forward and reverse as described above.
- By repeating the cleansing brush 600 is to repeat the forward and reverse rotation.
- the spring 800 is coupled to the holder 700 of the brushless electric motor 400, the spring 800 is deformed as the holder 700 rotates forward and backward.
- the spring 800 is made of a material having an elastic restoring force, when the spring 800 is bent due to the rotation of the electric motor 400 and the holder 700 is rotated, the point at which the rotation of the electric motor 400 ends. The strong torque is applied at, and the restoring force is maximized.
- the washing brush 600 in the present invention is a very fast forward and reverse rotation is made.
- the spring 800 is in a state of maximum bending, and when the reverse rotational force of the electric motor 400 is applied, the spring force is added and the reverse rotation is performed quickly. At the end of the reverse rotation, the spring 800 returns to its original position and then bends back to the maximum in the other direction, so that the rotation is performed while rapidly turning in the forward direction while the maximum torque is applied.
- the program code of the control circuit for forward and reverse rotation of the rotor of the electric motor 400 within a predetermined angle range can be stored in various devices, can be input to the control circuit to drive the bar, the computer-readable recording medium Examples include ROMs, RAMs, CD-ROMs, magnetic tapes, floppy disks, optical data storage devices, and the like, and also include those implemented in the form of carrier waves (eg, transmission over the Internet).
- the computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion. And functional programs, codes and code segments for implementing the present invention can be easily inferred by programmers in the art to which the present invention belongs.
- the present invention applies a brushless electric motor, but sets the operation mode so that the rotor of the brushless electric motor rotates forward and backward at a predetermined angle, and also generates a strong torque by the spring force, thereby making face cleansing more perfect. It provides advantages that can be done conveniently.
