The radiation generated by the motor is harmful to people

Radiation generated by the motor is minimal, because it is low-frequency 50 Hz emission capacity is weak, coupled with the shielding effect of the grounding of the chassis, so that the formation of that little bit of poor electromagnetic radiation and shielded off, so the motor of electromagnetic radiation is close to zero. There is no damage to the human body, not as bad as the noise generated by the motor on the human hearing damage of one ten thousandth of the big.
