重慶長基科技有限公司（簡稱BTL），公司科研團(tuán)隊經(jīng)過多年對空心杯電機(jī)核心部分——空心杯繞組技術(shù)的研發(fā)，已開發(fā)出大尺寸空心杯繞組全自動繞線機(jī)，打破了國外空心杯電機(jī)生產(chǎn)企業(yè)對此項(xiàng)技術(shù)的長期壟斷，是目前國內(nèi)大尺寸空心杯電機(jī)生產(chǎn)企業(yè)唯一掌握此技術(shù)的制造商，科研團(tuán)隊在此基礎(chǔ)上研發(fā)出一套精確的空心杯電機(jī)計算方法，所設(shè)計研發(fā)的無刷空心杯電機(jī)已達(dá)國際領(lǐng)先技術(shù)水平。

公司現(xiàn)階段主要研發(fā)與生產(chǎn)大尺寸（外徑16mm—100mm）、大功率、多極數(shù)、高轉(zhuǎn)速（可達(dá)12萬轉(zhuǎn)/分鐘）、最高效率可達(dá)93%的無刷空心杯電機(jī)，其產(chǎn)品已廣泛運(yùn)用到軍工、醫(yī)療、智能裝備、機(jī)器、新能源汽車、電動工具等領(lǐng)域。我們以“科技報國”為使命，致力于打造成空心杯電機(jī)自動化生產(chǎn)技術(shù)的引領(lǐng)者、空心杯電機(jī)民族品牌的領(lǐng)導(dǎo)者。

Chongqing Changji Technology Co., Ltd. (BTL) has developed a large-sized coreless motor, which represents a breaking of long-term technical monopoly by the counterparts overseas. Our company stands for the only manufacturer holding this patent in China, due to years of our R&D team’s effort on researching coreless motor winding technology. Our brushless coreless motor, adopting a new algorithm, also meets the advanced international standard.

We now focus on developing and producing large-size(O.D 16mm-100mm) and high-power brushless coreless motors which feature multipole mode 、high speed(up to 120thousand r/min) and top to 93% efficiency. It has widely used in military, medical, AI and machinery industry, as well as new energy vehicles, electric tools, etc.

Committing to ”serving our homeland by innovation”, our company aims to build an influential national brand leading in coreless motor technology and automatic production of it both at home and abroad.
