Laminated capacitor motor

Abstract

The invention belongs to the technical field of electrostatic motors, especially relates to a laminated capacitor motor. The laminated capacitor motor comprises a coil and a first rotating shaft fixedly connected with an output shaft. The coil is provided with four current Hall sensors, the first rotating shaft is sleeved with a plurality of layers of capacitor transmission components, the coil isin bridge connection with a first insulated bipolar transistor group, a second insulated bipolar transistor group, a third insulated bipolar transistor group and a fourth insulated bipolar transistorgroup, and the four current Hall sensors are respectively connected with the first insulated bipolar transistor group, the second insulated bipolar transistor group, the third insulated bipolar transistor group and the fourth insulated bipolar transistor group. According to the invention, the larger torque can be output in a smaller volume, and excessive requirements on materials and accurate control on the position of the rotor are not needed.

Description

technical field [0001] The invention belongs to the technical field of electrostatic motors, in particular to a laminated capacitor motor. Background technique [0002] Electromagnetic motors were born more than 100 years ago. Andrew Gordan invented electric bells and electric elastic cars that use the principle of repulsion of same-signal charges and attraction of different-signature charges. This can be regarded as the earliest example of using electrostatic drive. At present, the use of electrostatic motors is relatively small, because the dielectric constant is too small to provide excessive torque. The electrostatic motors currently available on the market or in the literature, such as asynchronous motors that use polarization relaxation, or capacitive synchronous motors have the largest It can reach the torque of Nm level. Nowadays, with the development of microelectronics, micromotors have become one of the current research topics. The above two methods have some sho...

Problems solved by technology

At present, the use of electrostatic motors is relatively small, because the dielectric constant is too small to provide excessive torque. The electrostatic motors currently available on the market or in the literature, such as asynchronous motors that use polarization relaxation, or capacitive synchronous motors have the largest Capable of torque in the Nm range

Nowadays, with the development of microelectronics, micromotors have become one of the current research topics. The above two methods have some shortcomings. Relaxation motors have high requirements for material control and manufacturing processes, and capacitor synchronous motors need to accurately control each The position of the rotor makes it difficult to make
