Title:
LONG-STROKE MOTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/048309
Kind Code:
A1
Abstract:
A long-stroke motion system, comprising: a stator (1) which comprises a stator base (11), and a permanent magnet array unit (12) and a transmission unit (13) that are arranged on the stator base (11), wherein the transmission unit (13) and the permanent magnet array unit (12) are both arranged according to a preset trajectory; at least one mover (2) which is slidably arranged with the stator (1) along the preset trajectory, and comprises a mover base (21), a coil array unit (22) and a plurality of sliding contact units (23); and a main control unit (5) which is connected to the transmission unit (13) and controls the mover (2). The sliding contact unit (23) comprises: a fixing member (231) which is arranged on the mover base (21); a conductive member (232) which is electrically connected to the coil array unit (22) and abuts against the transmission unit (13), wherein the conductive member (232) is operably electrically connected to and communicates with the transmission unit (13) when same abuts against the transmission unit (13); and a biasing member (233) which biases the conductive member (232) in a direction away from the fixing member (231). The long-stroke motion system has a simple structure and can stably run for a long time.
