Bundled linear motor actuator

Abstract

The invention discloses a bundled linear motor actuator, and belongs to the technical field of motor applications. A plurality of linear motors are connected in parallel into a combined linear motor actuator capable of synchronously outputting motion and power according to a specific rule and structure. The bundled linear motor actuator comprises an outer frame, a mover core, n groups of linear motion guide mechanisms and an automatic locking mechanism, wherein the section of the outer frame is a 2n-sided polygon; n spaced side walls are taken as stator mounting plates; two ends of the outer frame are fixedly connected with a top cover plate and a bottom plate respectively; stators are arranged on the stator mounting plates; the mover core is coaxially arranged inside the outer frame; the section of the mover core is a 2n-sided polygon; movers are arranged on side walls, which are opposite to the stator mounting plates, of the mover core; at least one end of the mover core is fixedly connected with an output shaft; the n groups of linear motion guide mechanisms are arranged between the mover core and the outer frame; the automatic locking mechanism is arranged on a side wall of the outer frame; and locking of the mover core and the outer frame is realized through the automatic locking mechanism. Through adoption of the bundled linear motor actuator, relatively great thrust force can be output, and the characteristics of high dynamic performance and greater output thrust force of a small motor are considered.

Description

technical field [0001] The invention belongs to the technical field of motor application, and in particular relates to a bundled linear motor actuator. Background technique [0002] Linear motor is a kind of transmission device that directly converts electrical energy into mechanical energy of linear motion without any intermediate conversion mechanism. Due to the adoption of "zero transmission", it has obvious advantages over traditional transmission methods, such as simple structure, no contact, no wear, low noise, fast speed and high precision. In recent years, with the continuous improvement of industrial processing quality and motion positioning accuracy, linear motors have received extensive attention. At present, the continuous thrust of Siemens SIMOTICS L-1FN3 series water-cooled linear motors reaches 8100N, and the maximum thrust can reach 20700N. However, compared with the hundreds of tons of thrust easily achieved by the hydraulic system, a single linear motor i...

Problems solved by technology

But as far as the current situation is concerned, the price of linear motors is still high, and the thrust quality is relatively small, so it is not practical and cost-effective in high-thrust low-speed occasions.
