A rotary motor driven by liquid metal

Abstract

The invention discloses a rotating electric machine driven by liquid metal, which includes a stator module, a rotor module, a power supply module and a bearing, wherein the stator module is composed of an upper motor frame, a lower motor frame and an annular water tank. The upper motor frame and the lower motor frame provide structural support for the rotating motor driven by liquid metal; the outer ring water tank of the annular water tank is filled with electrolyte solution to provide a solution environment for the liquid metal droplets in the rotor module. The rotor module consists of a motor shaft, a rotor frame, graphite electrodes, and liquid metal droplets. The liquid metal droplets in the liquid metal storage chamber on the rotor frame move to the high potential direction under the action of the driving electric field provided by the graphite electrodes, pushing the motor shaft to rotate. The power supply module is a dual-channel liquid metal conductive slip ring embedded in the motor to realize the external power supply of the motor. The rotating electric machine driven by liquid metal in the present invention is a new high-efficiency and low-cost torque output device, which has wide applicability and versatility, especially in the case of a locked rotor, the motor will not be burned due to overheating of the rotor coil.

Description

technical field [0001] The invention belongs to the technical field of electromechanical equipment, and relates to a continuous torque output device, specifically a liquid metal-driven rotary motor capable of continuously converting electrical energy into rotary mechanical energy. Background technique [0002] Motors are the core of electromechanical equipment and are widely used in social development. At present, the most widely used electric drive method is electromagnetic drive, which converts electrical energy into mechanical energy by using the principle that a universal wire is stressed in a magnetic field. However, electromagnetic motors require complex current reversing mechanisms or circuit control systems, and when the rotor frame is locked, the motor will overheat or even burn out. In addition, among the traditional motors, the electrostatic motor is a motor that realizes the rotation of the rotor through the Coulomb force between charges. It has the characterist...
