Winding-free end-part spiral-motion induction motor

Abstract

The invention discloses a winding-free end-part spiral-motion induction motor which comprises a shell. The shell is internally provided with stator winding straight-line part stator iron cores and stator winding end part stator iron cores; the stator winding straight-line part stator iron cores and the stator winding end part stator iron cores are provided with stator windings; a rotating shaft is provided with a rotor of the motor; the surface of the rotor of the motor is provided with a conducting layer of the rotor; and the rotating shaft is movably connected with the shell through a sliding bearing. The winding-free end-part spiral-motion induction motor adopts a set of stator windings, the straight line parts of the stator windings can generate a rotating-motion magnetic field, two end parts of the stator windings can generate a linear-motion magnetic field, and the two magnetic fields jointly act on the rotor of the motor to directly drive a load to do spiral motion. The invention omits the end parts of the traditional motor, two end parts of the stator winding, which can generate linear motion magnetic field, are completely symmetric to stator iron cores on two ends of the motor in space, the radial force can be eliminated, and the wear of the bearing can be reduced. The invention is simple in structure, low in manufacturing cost and small in volume, is easy to implement and is convenient to use.

Description

technical field [0001] The invention relates to a motor, in particular to a helical motion induction motor without a winding end. Background technique [0002] In the production and processing industry, the drive motors of devices such as auger drilling machines, screw conveyors, screw compressors, plastic extruders, and screw pumps all need to drive the shaft to perform screw motion. The traditional technology realizes the helical motion of the drive shaft through the mechanical combination of multiple motors. The solution in the traditional technology is not only quite complicated in the control method, but also requires a lot of expensive, bulky and cumbersome mechanical transmission devices. In addition, since the transmission components and bearings bear large axial force, the mechanical wear of these components is quite large, and the equipment loss is serious.

AI Technical Summary

Problems solved by technology

The stator windings of the rotary motor and the linear motor of the device are arranged on a pot-shaped outer rotor. Since the outer rotor directly drives the output shaft, the moment of inertia is large and the bearing wear is serious

At the same time, the disclosed invention patent also has the disadvantages of complicated mechanical structure, high processing cost, large device volume and inconvenient use.
