Single-phase brush rotary type electrostatic motor based on capacitance variable principle

A single-phase brush rotary type electrostatic motor based on a variable capacitance principle comprises a motor shell, four stator pole plates, a rotor pole plate, a commutator and an insulator rotating shaft, and is characterized in that the four stator pole plates are fixed in the motor shell after being subjected to insulation fitting treatment; the four rotor polar plates are fixed on the rotating shaft after being subjected to insulation fitting treatment, air gaps are reserved between the stator polar plates and the rotor polar plates, the electrostatic motor is driven by a high-voltage power supply, charges carried by the polar plates after being electrified interact to generate Lorentz force, and compared with a common electromagnetic motor, the electrostatic motor is mainly characterized in that the electrostatic motor does not have a process of generating magnetism by electricity, and the cost is reduced. Therefore, ferromagnetic loss does not exist, torque is directly generated by electrostatic fo
