Abstract: Electrostatic motor is a kind of energy conversion device using static electricity as energy source,with the advantages of simple structure and high no-load speed, which plays an important role in promoting the development of national economy and military technology. The existing electrostatic motor has a complex structure and needs position detection elements to change the motor operation state. The proposes a new capacitive electrostatic motor structure based on the working principle of electrostatic motor. The commutator brush structure reduces the complexity of the motor design and size,improves the motor output torque and energy conversion efficiency,and facilitates the rapid response and precise control
of the motor. In addition,the stator and rotor parts of the electrostatic motor do not have permanent magnets and excitation windings,which solves the problem of demagnetization of permanent magnets due to high temperature during high-speed operation.

Key words: electrostatic motor with brush construction,new structure,variable capacitance,efficiency
