Spiral stepping motor stator and rotor mechanism and spiral stepping motor

Abstract

Disclosed is a spiral stepping motor stator and rotor mechanism. A rotor comprises a central shaft and a plurality of rotor blocks, the rotor blocks are evenly arranged on a central circumference, adopting the central shaft as the shaft center and adopting one cylindrical post spiral line as a reference line, continuously or at intervals. A stator comprises a plurality of stator blocks, partitions and a cover plate. The stator blocks and the rotor blocks remain same distance radially, the operation surface axial width of the stator blocks is consistent with that of rotor blocks, and the stator blocks are flushed with the rotor blocks. When the motor operates, a dynamic spiral magnetic field is generated between the stator blocks and the rotor blocks, under the effect of the spiral magnetic field, the rotor blocks and the stator blocks perform non-friction linear and circumferential movements. The spiral stepping motor allows two components to perform circumferential movement and linear movement respectively and simultaneously or one component to perform circumferential movement and linear movement simultaneously.

Description

technical field [0001] The invention relates to a motor, in particular to a helical stepping motor in which a stator and a rotor can simultaneously move in different modes. Background technique [0002] Most of the existing motors are single moving parts. When two parts in the system need to move in different modes at the same time or the same part needs both circular motion and linear motion, it must be converted through an intermediate mechanism, resulting in complex structure and bulky equipment. Huge and expensive. The rotary motor must go through the intermediate link to achieve its linear drive capability. Although the linear motor has advantages in linear drive, it is expensive. Moreover, they have one characteristic in common: only one moving part. [0003] Although there is an electric motor that can satisfy the two parts to perform different movements at the same time, and also integrates the power and the transmission mechanism, its positioning accuracy is low a...

Problems solved by technology

[0003] Although there is a motor that can satisfy the two parts to perform different movements at the same time, and integrates the power and transmission mechanism, its positioning accuracy is low and the production cost is high.

[0004] Therefore, there is such a problem in the structure of the known motor: it is impossible to have two moving parts and at the same time, it must have high positioning accuracy, low production cost and integrate power and transmission mechanism.
