Embodiment Construction

[0022] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0023] A double-stator through-hole bearing permanent magnet gyro motor includes a stator 2, a rotor 1, a thrust plate 3 and a shaft 4. The innovation of the present invention is that the rotor is composed of bearing sleeve 7, magnetic steel 8, rotor ring 9 and magnetic conduction ring 10, the bearing sleeve is coaxially installed in the rotor ring, and the left and right sides of the rotor ring are symmetrically made into two ring-shaped installations. A ring-shaped magnetic steel is coaxially installed in each annular installation groove. The magnetic steel is a permanent multi-pole integral ring magnetic steel. A magnetic conduction ring is installed between the outer wall of each magnetic steel and the rotor ring. The rotor Both the ring...

Abstract

The invention relates to a permanent magnet gyro motor with double stators and a through-hole bearing. The permanent magnet gyro motor comprises the stators, a rotor, two thrust plates and a shaft, wherein the shaft is coaxially sleeved in a bearing hole of a rotor bearing cover; the two thrust plates are respectively arranged at the left and right ends of the shaft according to a working manner of a hydrodynamic gas-lubricated bearing, and are fixed by inner nuts; the left end and the right end of the rotor are respectively provided with a stator; and the two stators are fixed on a shaft by outer nuts. The permanent magnet gyro motor is scientific in design, and reasonable in structure. According to the technology, the aim that the three-phase permanent magnet gyro motor (with the double stators and the through-hole type hydrodynamic gas-lubricated bearing) of a position-free sensor is applied in the field of gyros can be realized, so that the precision of the gyro and an inertial navigation system can be obviously improved, and the permanent magnet gyro motor is advanced in technology, and fills the technology blank in China.

Description

technical field [0001] The invention relates to the field of gyroscopes, in particular to a three-phase permanent magnet gyroscope motor with double-stator through-hole bearings. Background technique [0002] The traditional permanent magnet gyro motor adopts an outer rotor, a single stator, and a split bearing structure. The rotor is placed outside the stator to meet the moment of momentum required by the gyroscope. The stator is inside the rotor and is fixedly connected with the shaft. Permanent magnets are placed on the rotor, and winding coils are placed on the stator. The stator winding passes the three-phase current to form the stator armature magnetic field, which interacts with the rotor permanent magnetic steel magnetic field to generate rotational torque, so that the motor rotates and achieves a synchronous state. The existing traditional permanent magnet gyro motor mainly has the following defects: 1. The stator is processed by glass-ceramics, and the coil is d...
