Physical Peculiarities of Corona-Discharge Motors

Resumo

This work is aimed at the study of the corona-discharge motor (CDM), whose torque is produced due to the electric dipole moment, which appears at the corona discharge. The physical mechanisms and features of the CDM operation that allow us to form a calculation base for the design and construction of the CDM, are identified and discussed. The motor power consumption, dipole moment generation, rotor torque as well as some specific effects inherent to this type of motor, arising from numerical calculations which take the pulse character of the supply voltage of the corona discharge into account, are considered. It is found that the motor rotation at a constant angular rate and a synchronous rotation with the torque are impossible. The obtained results can be used as a prerequisite for engineering calculations of the corona-discharge motors.
