Abstract

A miniature size electrostatic induction motor have been constructed and studied by applying a three phase ac power source with a maximum voltage of 5 KV and a variable frequency ranged 0.0 - 150 Hz. A maximum no load speed of the motor tested was about 7600 RPM at the applied voltage of 4330 volt and the frequency of 130 Hz for the case of the rotor surface material of polyprophylene sheet screen-printed $TiO_2$ powder on it. It is found that there are 3 different regions of the motor operation, a rotor stop region, a stable operation region and a high speed abnormal region. And it is also found that the motor speed is influenced greatly by the charge relaxation time constant of the rotor surface materials, which however was changed by the means of vapour-deposited Ti or Ni and screen-printed $TiO_2$ powder on the surface of the rotor material, polyprophylene.
