Linear motor

The utility model discloses a linear motor, through having offered transverse water channel on the iron core, the vertical water course in the collection stream block of transverse water channel rethread both sides links to each other, forms currenting direction inside, in time distributes away moving the heat that subcoil produced through currenting direction inside, avoids the heat to influencethe improvement of motor thrust. 本实用新型公开了种直线电机，通过在铁芯上开设有横向水道，横向水道再通过两侧集流块内的纵向水道相连，形成循环水道，通过循环水道及时把动子线圈产生的热量散发出去，避免热量影响电机推力的提高。
