Abstract

The invention discloses a frameless combined type permanent magnet synchronous motor. The frameless combined type permanent magnet synchronous motor comprises a stator pedestal, the stator pedestal is internally provided with a cooling cyclic water pipe, the outer side of the stator pedestal is provided with an adjustment plate, the stator pedestal is provided with a stator assembly, the stator assembly is provided with an upper support, the inner side of the stator assembly is provided with a rotor assembly, and the frameless combined type permanent magnet synchronous motor further comprises an encoder, and the encoder is installed at an inner-side axle center of the rotor assembly through the upper support. The frameless combined type permanent magnet synchronous motor has the following advantages: the apparatus is flexible in structure and convenient to install; the motor is easily organically integrated with a driving apparatus for realizing direct driving; and the bottleneck of difficultly in manufacturing a large-power and large-diameter motor is eliminated.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a frameless combined permanent magnet synchronous motor. Background technique [0002] It has been more than 100 years since permanent magnets were used as magnetic potential sources to manufacture motors. The world's first motor invented by Barlow in 1831 was a permanent magnet motor. The magnetic properties of early permanent magnet materials were very low, and permanent magnet motors were quickly replaced by electric excitation motors. In the 1930s and 1950s, the emergence of AlNiCo (AlNiCo) with high remanence Br and ferrite (Ferrite) permanent magnet materials with higher coercive force Hc brought vitality to permanent magnet motors. . However, the Hc value of AlNiCo is very low, and it is easy to lose magnetism. The Br value of Ferrite is very small, which cannot provide high working magnetic density for the motor, and power electronic devices such as inverters have not be...
