品牌Parker派克產(chǎn)品類型永磁同步電動機 型號ST 系列永磁無刷伺服電機極數(shù)12極 額定功率735-3850W額定電壓400VDC（V） 額定轉速30-1500（rpm） 產(chǎn)品認證CCC 應用范圍對轉矩和功率要求較高的場合，且要求非常低的速度和重量的情況下

stk系列力矩電機

力矩電機的顯著特點就是能夠在較低轉速時產(chǎn)生大的轉矩。 力矩電機有相對多的級數(shù)，且可以提供空心軸和實心軸兩種選擇。減速機的缺少極大的改進了力矩電機在旋轉應用領域的動態(tài)特性。st和stk兩個系列的力矩電機被廣泛應用于要求旋轉的領域中，作為普通風冷的替換選項，強制風冷和水冷都已經(jīng)成為可能。

stk系列永磁無刷伺服電機采用特殊直接驅動設計（無減速機），特別適合應用在對轉矩和功率要求較高的場合，且要求非常低的速度和重量的情況下。

高度完美的電磁和熱力學優(yōu)化設計，使得電機的額定轉矩、重量比達到14nm/kg(自然冷卻)，31 nm/kg(水冷)。

with the stk range, parker offers a solution for direct driveapplications. examples include:
xx applications needing total integration of the motor within the servomechanism due to volume and/or weight considerations xx applications needing a large-diameter hollow shaft demanding a ring-type technology。

main characteristics

xx continuous torque from 14nm to 2 700nm with natural convection (according to size), and up to 6 100nm with
fluid cooling.
xx six external diameters from 145mm to 800mm.
xx internal diameters from 56mm to 630mm.
xx various windings available from 30rpm to 1 500rpm according to size.
parker’s stk range of permanent magnet brushless motors has been specially designed for direct drive (without a gearbox),particularly in applications needing very low volume and weight in relation to the torque and power re
electromagnetic and thermal optimisation has permitted continuous tor ratios up to 14nm/kg to be achieved with natural convection and up to 31nm/kg with fluid cooling.
the parker stk range of frameless motors addresses very demanding industrial applications, not only in terms of performance(dynamic performance, torque capability and precise rotation at low speed) but also in terms of cost. particular attention has therefore been paid in the design to the combination of technical and economic optimisation.
industrial users can sometimes be dissatisfied with direct drive servo systems because they are fre based on torque motors with limited power and speed capability. with the stk range, parker set out to counter this objection by creating motors that could not only satisfy low-speed applications with their associated speed regulation, but could also address direct drive applications up to 30kw in natural convection at speeds up to 1 500rpm.
the various speed ratings are achieved by having a range of available windings. some of these are illustrated in the catalogue, but numerous winding variations are possible to allow the drive system to be optimised.
