A deep slot single-phase capacitance operation linear motor

Abstract

The invention discloses a deep-slot type single-phase capacitor running linear motor. It includes a primary and a composite secondary, and the primary units are arranged along the conveying line in a spaced distribution manner. It is characterized by: 1) Each primary iron core is provided with 4 deep grooves, and the ratio of the groove height to the groove width is 6~ 12. The windings in the slot are placed in layers; 2) The primary main winding and the secondary winding are asymmetrical, the number of turns and wire diameter are not equal, the secondary winding is connected in series with a capacitor C, and the primary winding is connected in parallel with the secondary winding after the series capacitor. The control switch is connected to the power supply; 3) The secondary operates in one direction relative to the primary, and the secondary is a copper-iron composite structure. The linear motor directly drives the load to run, with simple structure, low starting current, low noise, high efficiency, no need for lubrication, and high reliability. Its one-way movement meets the requirements of logistics conveyor lines, and is suitable for various types of production and commercial logistics lines in linear motion occasions, especially in supermarkets, pharmaceutical and civil logistics lines.

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 starting current, small impact, h...
