A deep slot single-phase capacitance operation linear motor

Abstract

The present invention discloses a deep slot type linear electric motor running with single-phase capacitance. The electric motor includes two levels: the primary and the combined secondary, wherein the primary unit is positioned along the transmitting line in an interval distribution modus. The characteristics are: 1) four deep grooves are positioned on each primary iron core, wherein the ratio of the highness and the width of the groove is 6~12 and the windings are layered in the groove; 2) the primary main winding is unsymmetrical with the secondary winding which is connected to a capacitor C in series, and the turn number is not identical to the line radius, and the main winding is connected to the secondary winding which is connected to a capacitor C in series in parallel and is connected to the electric power source gate through a controllable switch; 3) the secondary winding is in a single phase running relative to the primary and has a cuprum-iron compound structure. The linear electric motor drives the load directly and has a simple structure, a small starting current, a low noise, a high efficiency and a high reliability. The single-phase running of the linear electric motor satisfies the requirement of the physical distribution conveying line and is adaptable for the production and the situation in which the physical distribution line in commercial use is running in a straight line of any types of linear electric motors and is especially adaptable for the physical distribution lines in supermarket or medicine use of common people.

Description

technical field [0001] The invention belongs to single-phase linear motors. In particular, a deep-slot single-phase capacitor-operated linear motor. Background technique [0002] In many occasions such as logistics conveyor lines that require linear motion, it is usually realized by a rotating motor plus an intermediate conversion mechanism such as a sprocket and a belt. The system structure is complex, the noise is large, the efficiency is low, and there are problems such as lubrication pollution. [0003] The single-phase linear motor used in the logistics conveyor line needs to be started frequently, and the running time is extremely short. It is quite unfavorable to use the existing single-phase linear motor operated by a capacitor. For this reason, a single-phase linear motor with direct drive mode is proposed, especially a linear motor with deep groove single-phase capacitor operation: its structure is simple, and because of its small s...
