试用计划使机器建筑商评估无刷PM电机

Novatorque,Inc。一家位于Sunnyvale CA的高效率,具有成本效益,永久磁铁电动机的生产商,为原始设备制造商(OEMS)提供了无需成本的机会,以评估和测试Novatorque的新Gen 2.0 PremiumPlus+™电动机。

需要合格的OEM才能填写评估系统请求表,提供用于跟踪目的的采购订单,参加与Novatorque进行的预审会议,以审查申请和测试计划,并提供估计年度使用的信息。参加该计划的OEM还必须在运输后60天内完成测试,参加测试后会议,讨论结果,并在60天结束时返回或购买该系统。

在可变驱动器的驱动下,Novatorque的Gen 2.0 Premiumplus+™无刷的永久磁铁电动机的额度额定速度效率分别为93.0%和92.0%,分别为3HP和5HP版本,远远超过了诱导电动机所达到的水平。相比之下,3HP和5HP NEMAPremium®感应电动机在可变的频率驱动器驱动时,仅在88.5%至89.0%之间达到仅电动机效率。

“除了在额定点上具有较高的效率外,Novatorque的Premiumplus+™电动机在较大的速度和负载范围内保持高效率。速度降低导致负载减少75.0%。在减少负载下,Novatorque Motors将保持效率约为91%,而NEMA高级效率感应电动机将下降到80%。与之相比,优势更加巨大。当前已安装的感应电动机基地在20%或更多的地方可以实现。” Novatorque销售副总裁Scott Johnson说。

重要的是,由于其独特的专利通量定子和转子轮毂几何形状,Novatorque Motor通过全含力(相对于稀土)磁铁设计产生了这种性能。

"The cost of rare earth (neodymium) magnet material, the basis of most conventional permanent magnet motors, has risen dramatically and is now more than 25 times the cost of ferrite. Further, supply of rare earth magnets, nearly sole-sourced out of China, is increasingly uncertain. The ability to use ferrite magnets allows NovaTorque to price its motors comparable to induction motors. This means OEMs and HVAC systems builders can now economically deliver permanent magnet motor efficiency with their systems" explains Johnson.

NovaTorque PremiumPlus+™ motors are packaged in standard NEMA frame sizes and mounting dimensions for easy substitution. Due to their high power density, NovaTorque motors are available both in the mounting frame size typical for induction motors, as well as one frame size smaller. NovaTorque PremiumPlus+™ motors are compatible with readily available variable frequency drives (VFDs) from most leading manufacturers, including ABB, Yaskawa, Mitsubishi, Fuji, Hitachi, Toshiba and others.
