Problems solved by technology

However, multiple motors working at the same time not only increase the complexity of the system, but also increase the cumulative error, reducing the reliability and sensitivity of the system; for motors that can output shaft power or torque to any angle, there is still a blank state in the market.

Abstract

The invention provides a universal motor, namely a space three-degree-of-freedom spherical motor which comprises a permanent magnet rotor, a stator coil, an annular base, a spherical crown bearing, aHall sensor, a chip servo system and a relay, the permanent magnet rotor is located above a stator, a spherical crown bearing structure is arranged between the permanent magnet rotor and the stator, and the gravity support is fixedly connected with the stator base; the top of the permanent magnet rotor is in rigid connection with a rotor shaft, the rotor shaft and the permanent magnet rotor are ofan integrated structure, and multiple sets of spiral grid type wires / coils are arranged on the stator base. The chip servo system comprises an IC chip and a relay / current adjusting unit electricallyconnected with the IC chip. The universal motor is used for solving the technical problems that in the prior art, when shaft power or torque is output in multiple directions, a plurality of motors need to be matched with a servo system to work at the same time, the system complexity is increased, and the system reliability and sensitivity are reduced.

Description

technical field [0001] The invention relates to the field of chip servo motor systems, in particular to a universal motor, especially a spherical universal motor with three degrees of freedom in space. Background technique [0002] The motor is an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. Its main function is to generate driving torque as a power source for electrical appliances or various machines. The existing motor technology has formed a relatively complete and sound system after hundreds of years of development. Its working mode is mainly to continuously output shaft power or torque in a fixed direction. When it is necessary to output shaft power in multiple directions, it often requires multiple The two motors work with the servo system at the same time. However, multiple motors working at the same time not only increase the complexity of the system, but also increase the a...
