Abstract

The invention discloses a method for reducing horizontal and longitudinal end part effects of a linear induction motor. The method comprises a first method, the longitudinal end part effect is reducedby changing a primary shape, the shape of stator tooth at a primary longitudinal end part employs a right triangle, a bevel edge of the right triangle faces outwards, and the longest one of two right-angle edges faces a secondary side. By the method, the problems of the longitudinal end part effect and the horizontal end part effect of the linear induction motor are solved; by the method for reducing the horizontal and longitudinal end part effects of the linear induction motor, the problems that a primary winding current is asymmetric in three phases, end surface flux occurs at a disconnection part, an electric transient phenomenon is generated through cutting a magnetic field generated by the secondary side by a magnetic field generated by the primary side during the motion process of the linear induction motor and a semi-filling groove is formed in a winding end can be effectively prevented, the fluctuation of output thrust is greatly reduced, the output efficiency of the linear induction motor is improved, the heating quantity of the linear induction motor is reduced, and the service lifetime of the linear induction motor is prolonged.

Description

technical field [0001] The invention relates to the technical field of linear motors, in particular to a method for reducing lateral and longitudinal end effects of linear induction motors. Background technique [0002] Traditional driving devices mostly use rotating motors plus transmission devices (such as gears, rollers, chains, transmission belts, etc.), which no longer meet the increasing demands for high-precision and high-efficiency processing today. Traditional bearings generate friction and heat during work, and worn bearings need to be replaced regularly, and the transmission device is large and difficult to move. Linear motors can improve work efficiency, reduce power consumption, and do not require complicated transmission devices. Obviously, linear motors are used instead of traditional ones. The power system composed of rotating motors and bearings is more economical, convenient, and better able to meet processing needs. The fundamental difference from rotating...
