英國(guó)帕瓦魯斯PARVALUX已有將近六十五年的歷史,公司一直致力于生產(chǎn)和研發(fā)減速馬達(dá)的解決方案，在各地都大量的OEM客戶。擁有超過(guò)1800萬(wàn)齒輪馬達(dá)的現(xiàn)貨庫(kù)存，作為英國(guó)的分馬力電機(jī)的制造企業(yè)之一，Parvalux為客戶提供廣泛和可靠的定制直流和交流電機(jī)而獲得了良好的聲譽(yù)。
英國(guó)帕瓦魯斯PARVALUX伺服電機(jī)（PARVALUX servo motor ）是指在伺服系統(tǒng)中控制機(jī)械元件運(yùn)轉(zhuǎn)的發(fā)動(dòng)機(jī)，是一種補(bǔ)助馬達(dá)間接變速裝置。伺服電機(jī)可使控制速度，位置精度非常準(zhǔn)確，可以將電壓信號(hào)轉(zhuǎn)化為轉(zhuǎn)矩和轉(zhuǎn)速以驅(qū)動(dòng)控制對(duì)象。在自動(dòng)控制系統(tǒng)中，用作執(zhí)行元件，把所收到的電信號(hào)轉(zhuǎn)換成電動(dòng)機(jī)軸上的角位移或角速度輸出。分為直流和交流伺服電動(dòng)機(jī)兩大類，其主要特點(diǎn)是，當(dāng)信號(hào)電壓為無(wú)自轉(zhuǎn)現(xiàn)象，轉(zhuǎn)速隨著轉(zhuǎn)矩的增加而勻速下降。
近年來(lái)矚目共睹的是Parvalux在銷(xiāo)售和生產(chǎn)電機(jī)和齒輪箱上不斷加速。其中基礎(chǔ)的變化是把客戶的意見(jiàn)納入我們決策過(guò)程。不再是簡(jiǎn)單的生產(chǎn)減速電機(jī)的工程公司，我們正在變成一個(gè)‘客戶’的公司－碰巧是生產(chǎn)減速電機(jī)的企業(yè)。 英國(guó)PARVALUX交流伺服電機(jī)的控制精度由電機(jī)軸后端的旋轉(zhuǎn)編碼器保證，由于驅(qū)動(dòng)器內(nèi)部采用了四倍頻技術(shù)，驅(qū)動(dòng)器每接收一個(gè)命令=131072個(gè)脈沖，相當(dāng)于PARVALUX電機(jī)轉(zhuǎn)一圈，PARVALUX交流伺服電機(jī)運(yùn)轉(zhuǎn)非常平穩(wěn)，即使在低速時(shí)也不會(huì)出現(xiàn)振動(dòng)現(xiàn)象。其交流伺服系統(tǒng)具有共振抑制功能，可涵蓋機(jī)械的剛性不足，并且系統(tǒng)內(nèi)部具有頻率解析機(jī)能（FFT），可檢測(cè)出機(jī)械的共振點(diǎn)，便于系統(tǒng)調(diào)整。PARVALUX交流伺服電機(jī)具有較強(qiáng)的過(guò)載能力。其轉(zhuǎn)矩為額定轉(zhuǎn)矩的三倍，可用于克服慣性負(fù)載在啟動(dòng)瞬間的慣性力矩。PARVALUX交流伺服驅(qū)動(dòng)系統(tǒng)為閉環(huán)控制，驅(qū)動(dòng)器可直接對(duì)電機(jī)編碼器反饋信號(hào)進(jìn)行采樣，內(nèi)部構(gòu)成位置環(huán)和速度環(huán)，一般不會(huì)出現(xiàn)步進(jìn)電機(jī)的丟步或過(guò)沖的現(xiàn)象，控制性能更為可靠。
英國(guó)帕瓦魯斯PARVALUX公司主要產(chǎn)品有：PARVALUX電機(jī)、PARVALUX伺服電機(jī)、PARVALUX微型電機(jī)、PARVALUX驅(qū)動(dòng)器、PARVALUX控制器、ARVALUX減速機(jī)、PARVALUX小馬達(dá)、PARVALUX交流直流減速調(diào)速電機(jī)、PARVALUX減速馬達(dá)、齒輪減速電機(jī)、減速步進(jìn)電機(jī)、PARVALUX可逆同步電機(jī)、伺服步進(jìn)電機(jī)、永磁直流電機(jī)、PARVALUX離合制動(dòng)電機(jī)、力矩電機(jī)、二極電機(jī)、電動(dòng)機(jī)、PARVALUX震動(dòng)馬達(dá)、PARVALUX微電機(jī)、PARVALUX交流電機(jī)等。
The name ‘Parvalux’ derives from the latin ‘parvulus’ and ‘lux’ and means ‘young light’, alluding to the hopes that founder Leslie J. Clark had for the Romford-based business where he first began selling motor rewinds in 1947.
After relocating to Bournemouth in 1957, the company moved from simply re-winding motors to designing and manufacturing complete gear-motor units for industrial applications.
Parvalux prospered for forty years through continued expansion of its product offer to cover a broad range of AC/DC electric motors and gearboxes, enabling the business to sell into a diverse range of markets and applications ― all over the world.
In 2003, Steven Clark took over as Chief Executive. With over twenty years experience within Parvalux, Steven was keen to see the business prosper, therefore recruited a professional management team.
In 2008 Parvalux acquired rival firm and DC motor application specialist EMD Drives Systems of Halstead, thereby creating the UK’s largest privately-owned manufacturer of sub 1kW electric motors and gearboxes.
Until that time EMD had shared a similar history to Parvalux, initially winning recognition in the 1960s as volume AC motor supplier to household names such as Qualcast and Hotpoint, but then moved exclusively into DC products by the 1980s where they would compete directly with Parvalux for some 30 years.
EMD was relocated in its entirety to the Bournemouth headquarters during early 2009. The team was strengthened with key members of the EMD team relocating to join the newly merged business.
The integration allowed Parvalux to offer geared motor solutions in much higher quantities than previously possible. To cement this unique position a first class ‘product development and design’ function (PDD) was created.
Today, Parvalux remains a privately owned, professionally managed business with distributors in 21 countries.
