The invention relates to a linear motor of a cylindrical-type and flat-type hybrid structure. The linear motor comprises a permanent magnet of a flat-type linear motor, a primary winding of the flat-type linear motor, a connecting piece, a brake, a primary winding of the cylindrical-type linear motor and a secondary winding of the cylindrical-type linear motor, wherein the primary winding of the cylindrical-type linear motor is connected with the primary winding of the flat-type linear motor through the connecting piece, and the brake is installed on the connecting piece. The cylindrical-type linear motor is mainly used for improving the primary winding of the flat-type linear motor, and the flat-type linear motor is used for providing a thrust force for a lift platform. The lifting of the lift platform can be completed through the alternating circulating running of the cylindrical-type linear motor and the flat-type linear motor as well as the matching of the brake. By adopting the linear motor with the hybrid structure, the quantity of the primary windings can be greatly reduced, and the system cost can be reduced. The advantage of the linear motor with the hybrid structure is relatively obvious along with the increment of the lifting height.
Description
technical field [0001] The invention relates to a linear motor, in particular to a linear motor with a cylindrical and flat hybrid structure. Background technique [0002] The most prominent advantages of cylindrical linear induction motors are simple structure and low cost, but linear induction motors have low thrust density and low efficiency, and there is a large copper loss in both the primary pole and the secondary pole. When applied to a cordless vertical lifting device, the power required by the motor is very large, and the electromagnetic load is high. If the long primary pole segmented electrification technology is adopted, the mover is a composite secondary pole. The advantage is light weight and simple structure. The disadvantage is that it will It will generate a large amount of heat and cause serious deformation, so it is not suitable for applications with high thrust density; if a long secondary pole structure is used, similar to the form of a linear motor subw...
