无刷电机直接驱动离心机是由电机带转子高速旋转的。过去的电机是带碳刷的直流电机,离心机运转时碳刷磨损,带来火花与噪声甚至振动,且有寿命,届时要更换碳刷再行运转。更严重的是碳刷的磨损带来碳粉尘的污染,不仅污染离心机,还会污染周围环境,这种污染对卫生行业是不合适的。
当转子高速旋转时,空气摩擦生热,转子温度会上升,试管中的样品温度也会升高。由于生物学样品对温度敏感。一般要求离心实验中温度保持4℃。没有电脑控制的智能化技术,是不可能做到这样精度的。因此,用制冷机对离心腔冷却,而达到冷却转子、冷却样品温度的目的。但测量旋转中的转子的实际温度极为困难,都采用在离心腔底部离转子较近处埋设温度传感器,间接测量转子温度。血型离心机T补偿又与转子的类别、转速及运行时间有关。
无刷电机离心机性能:
以前模拟技术典型的表现形式为旋钮选择操作参数(如转速、温度与时间等),以表盘的指针来显示数据。现在运用数字技术,典型的表现形式为界面友好、键盘操作、数字化显示、可编程操作的全电脑控制,其核心为智能化控制,是由电脑来实现的。离心机操作所需要一切参数(如转速、温度、时间、加减速率档等),键盘操作输入,并以数字显示出来,因此选择操作参数与读取数误差极小。其缺点为:选择参数与数据的读数值受操作人与读数人的人为干扰多,控制精度差。而且每次操作都要这样,重复性差。有的离心机虽数字显示(如旋钮选值而数字显示),虽在读数上有改进,但取值原理未变仍属模拟技术又由于是可编程操作,可把一组操作参数编成号码,可存取使用。

1 科学调整
直流机电作发电运行时,电枢由原念头驱动而在磁场中旋转,在电枢绕组的两根有用边中感应出电动势;而当电念头运行时,将直流电源接在两电刷之间而电畅通流畅进电枢绕组,其工作原理基本分歧。发机电的电磁转矩是阻转矩,它与电枢转动的标的目的或原念头的驱动转矩的标的目的相反;而电念头的电磁转矩则是驱动转矩,它使电枢转动,有着本质的区分。是以,电念头的电磁转矩必需与机械负载转矩和空载消耗相平衡。一般来说,当轴上的机械负载发生变化时,则电念头的转速、电动势、电流和电磁转矩将自动进行调整,以顺应负载的变化,连结新的平衡。但当电念头使用时间较长或受负载发生急剧变化时,应当进行人工调整,以避免负载突然加年夜或失衡,致使电念头长时间运行而损坏。
