Electric motors are widely used in many home electric system that produce actuating task such as home appliance vacuum cleaner. The main problems for vacuum cleaner is large noise when at high-speed rotation. Therefore many researchers and companies are developed new technology for suppressing motor noise. Generally speaking, it is very difficult to suppress noise, since the motor noise is generated by various factors. In this paper, we focus on characteristics of human perception from ears. Instead of suppress motor noise, we control motor noise spectrum according to human perception. To control motor noise spectrum, motor control driver that may control motor rotational speed and motor noise spectrum independently is necessary. In order to confirm the basic idea of proposed motor control driver, we develop basic prototype and validate simple experiments.
