Description
Technical field
The present invention relates to permanent-magnetism linear motor technical fields, and in particular to a kind of lift-on/lift-off type is without track linear motor.
Background technique
Current linear motor is largely pellet type load, i.e. load is mounted on mover top.But some special
Application, such as trussing, power window etc., need load be lifted on mover in the following, this sliding system is proposed it is very high
Requirement, often require to use the sliding block for capableing of multi-panel stress and guide rail to do sliding system, system cost caused to rise.Together
When, the linear motor of all manufacturer's productions, is required to spread the track being made by alternate permanent magnet on stator at present.The spy
Sign causes motor cost to increase, reduced lifetime, and security risk is big.In order to meet the needs in low cost lifting market, expand straight line
It is particularly necessary without track linear motor to design a kind of simple and convenient lift-on/lift-off type for the application range of motor.
Summary of the invention
In view of the shortcomings of the prior art, object of the present invention is to be to provide a kind of lift-on/lift-off type without track straight-line electric
Machine, it is reasonable in design, use cheap wheel as sliding support system, and without placing permanent magnet on stator；
Low in cost, installation and transportation are simple, and security risk is small, use easy to spread.
To achieve the goals above, the present invention is to realize by the following technical solutions: a kind of lift-on/lift-off type is straight without track
Stator, motor right side stator and hoisting connecting piece, motor on the left of line motor, including shell sectional bar, electric mover, wheel, motor
Stator is embedded in shell sectional bar on the right side of the Stator and electrical machine of left side, and hoisting connecting piece is placed between two stators, wheel installation
On electric mover, electric mover and stator are kept at a distance by wheel support, and hoisting connecting piece is fixed on electric mover, electricity
There is no permanent magnet on stator on the right side of Stator and electrical machine on the left of machine, using no track structure.
Preferably, the shell sectional bar is adopted as aluminum hull, steel shell or plastic housing.
Preferably, the wheel material uses plastic-steel, nylon, polyacrylamide or polyvinyl lactam.
Preferably, stator, motor right side stator are made of permeability magnetic material on the left of the motor, permeability magnetic material includes
There are silicon steel sheet, pure iron, electrical sheet, permalloy.
The invention has the following advantages:
(1) present invention uses lift-on/lift-off type structure, and hoisting connecting piece can be stretched out below mover, is suitable for lifting operation；
(2) present invention reduces the raw material and production processing cost of motor using no track stator, while it is difficult to reduce protection
Degree, reduces electromagnetic interference, so that the motor more secure and reliable, longer life expectancy；
(3) present invention realizes other linear motors and is difficult to together by combining by hoisting structure and without track stator feature
When have low cost and lifting operation advantage, have boundless prospect in linear motion system.
