Problems solved by technology

The former increases the requirements for the levitation force of the levitation electromagnet (that is, the excitation magnetic potential) and the dynamic response of the levitation, which affects the efficient use of the traction force.
The latter increases the friction of the wheel and rail and reduces the traction efficiency

Abstract

The invention discloses a tractive carrying device of straight line inductive motor, which adopts single-side short junior straight line inductive motor to provide suspending / unloading and tractive power, wherein the single-side short junior straight line inductive motor consists of overlapping ferric core [31] and junior [3] of winding [32] in the ferric core grove on two sides of bulk; when the surface of junior [3] faces upwards, the low grade fixed on two sides of rail; when the surface faces downwards, it opposites the surface of motor junior [3]; the low grade is made of aluminium or copper long reacting board [4] with back displaying excellent magnetic conductive steel board [5]; the reacting board and steel board are fixed on the rail beam [6].

Description

technical field [0001] The invention belongs to the field of motors, in particular to a linear induction motor carrying device used in the carrying field. Background technique [0002] The use of linear motors can save the necessary gear mechanism when using rotary motors, and directly realize linear drive. Therefore, it is widely used in mechanisms that require linear motion. In the field of rail transportation, compared with the wheel-rail transportation system driven by rotating motors, the transportation system driven by linear motors has the advantages of low noise, strong climbing ability, small turning radius, and low construction and operation costs. Compared with other motors such as linear synchronous motors, the unilateral linear induction motor system has the characteristics of simple structure, low cost, less maintenance, reliable operation, and easy realization of frequency conversion control. Therefore, the unilateral induction linear motor has been actively...
