Electric table turntable driven by circular magnetic field

Abstract

The invention relates to a dining table electric rotary disk based on driving of a toroidal magnetic field. The dining table electric rotary disk comprises a base and a rotary disk body. A rail ring is arranged between the rotary disk body and the base. A plurality of evenly distributed steel balls are arranged on the rail ring. The rotary disk body is arranged above the base through the steel balls and can rotate on the base through the steel balls. A plurality of annular concave iron cores are arranged on the inner side of the rail ring and located on the base. Three-phase coil windings are embedded in the annular concave iron cores and are electrically connected with a rotary controller, and the rotary controller is electrically connected with a switch. A salient pole type permanent magnet with alternate N poles and S poles is arranged above the annular concave iron core and is fixedly installed on the lower surface of the rotary disk body. The rotary controller controls the conduction of the three-phase coil windings through on-off signals inputted through the switch so as to enable the applying force generated through matching between the three-phase coil windings and the permanent magnet to push the rotary disk body to rotate on the base. The dining table electric rotary disk is simple and compact in structure, low in using cost, high in rotating control accuracy, wide in application scope, safe, and reliable.

Description

technical field [0001] The invention relates to a table turntable, in particular to an electric table turntable driven by an annular magnetic field, which belongs to [0002] It is used in the application field of electromagnetically driven dining table electric turntable technology. Background technique [0003] The existing table turntables are basically pushed by hand, and among the few electric table turntables, no matter what method is used, a DC or AC motor is used as an actuator to directly or indirectly drive the turntable to rotate. Due to the addition of the motor, many design methods make the turntable larger, unsightly and practical, and more importantly, different design ideas have different requirements for the rotating motor, thus increasing the cost. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies in the prior art and provide an electric table turntable driven by an annular magnetic field, which has a...
