Abstract

Provided is a noise remover of a PWM motor without a frequency control filter in a PWM control motor, and more particularly, the noise remover includes a micom formed in a vehicle terminal and converting to and transmitting the frequency avoiding the radio frequency; a frequency filter for suppressing the noise converted by the micom; a motor part for transmitting the frequency that the frequency filter outputs to a vehicle motor, and operating the motor; and a pulse modulation / demodulation control part for controlling the rotation amount of the vehicle motor inside the motor part, which are divided roughly as four, and rotate a rotor of the motor part without noise by selectively applying the frequency which is not overlapped with radio frequency to a first FET, a second FET, a third FET, and a fourth FET.

Description

technical field [0001] Embodiments of the present invention relate to a noise remover for a PWM motor without a frequency control filter, and more particularly, to a noise remover for a PWM motor without a frequency control filter, which includes: a microcomputer in a mobile terminal , which transmits the frequency after converting to a frequency avoiding radio frequency; a frequency filter, which converts the noise converted by the microcomputer; a motor part, which sends the frequency output from the frequency filter to the moving vehicle motor to operate the motor ; and a pulse width modulation (PWM) control section for controlling the amount of rotation of the vehicle motor within the motor section, which is divided into four sections so as to control the motor section by selectively applying a frequency that does not overlap with the radio frequency to the motor section The first FET, the second FET, the third FET and the fourth FET are used to rotate the rotor of the mot...
