高速电动机发电机

高效率和功率密度

Calnetix Technologies designs, develops and manufactures a wide range of high-speed permanent magnet (PM) motor generators for a variety of applications and industries. Our high-speed motors and high-speed generators are designed based on a flexible modular structure, developed using technologically advanced engineering methods.

我们开发自定义系列电动机和发电机OEM manufacturers that make their products more innovative and competitive. Calnetix’s permanent magnet motors are the preferred choice for large compressor, blower and vertical pump applications. We are also a key supplier of subminiature PM motors used in artificial hearts and other blood pumps. Calnetix’s permanent magnet generators are used in small auxiliary power units (APUs), as well as large industrial power generations systems.

Advantages

由于旋转速度较高,磁轴承的使用,CalNetix的高速电机和高速发电机提供较小的占地面积,重量较轻,效率更高,可靠性更高,维护更高,而不是传统的齿轮机。我们的电动机和发电机的范围从兆瓦到兆瓦的功率水平,速度范围为4,000 rpm至450,000 rpm。CALNETIX的高速电机发电机提供以下优点:

高速电机运行

当电机可以比60 Hz电力系统施加的3,600 rpm限制更高的速度操作,具有更小的效率。固态逆变器消除速度限制。给定机器的功率额定值直接增加速度,直到达到结构,热或​​动态稳定性限制。良好的高速设计是这些限制与和谐相处的地方。

通过交易速度的扭矩,固态变频器具有独特的改变能力的频率使得能够实现以下优点:

  • 能够大大降低电机的大小,复杂性和重量

  • 能够使用不需要隔热绕组,滑环和滑动触点(刷子)的更强大的转子

  • 能够容纳高达3,000 Hz的频率

高效率和高温电机运行

专有的设计过程和材料选择用于满足客户应用的需求,包括效率和温度要求。好处包括:

  • Reduced losses at the component level through the use of special coatings and manufacturing methods

  • 通过使用热管理和高性能封装技术,在恶劣环境环境中运行高达90˚C的能力

High Power Density Motor Performance

For applications where light weight is of utmost importance, such as in aerospace and motorsports, Calnetix’s high-speed motors and generators are designed to provide maximum power density while maintaining high operating efficiency and good thermal performance consistent with design requirements. An example of a power dense machine that we have designed and manufactured is rated at 100 kW and weighs 7.7 kg in a 2.3-liter volume, which is equivalent to a machine power density of 13 kW/kg and 43 kW/liter. Calnetix is able to achieve such high-power density due to the following:

  • 电磁设计优化,包括磁化拓扑

  • 优化机器的L / D(长度直径)纵横比

  • 优化磁路

  • 材料的选择,包括磁铁等级,定子叠片及其厚度,磁体保持套管和其他材料

Calnetix High Power Density

Optimized Performance by Application

Calnetix’s high-performance motors and generators can be designed along with magnetic bearings and high efficiency variable speed drives (VSD) completely in-house. This enables us to achieve the most compact, optimized solution for each application without compromising any inherit benefits, such as high-speed, high-efficiency operation and zero maintenance requirements. The special construction features and fabrication of our high-performance stators and rotors provide some unique benefits, including:

  • Optimized stator configuration due to utilizing in-house tools, such as fill factor, end-turn bundle and neutral termination techniques

  • High back EMF per magnet volume with high magnetizing efficiency due to the rotor’s ability to magnetically couple to the stator with minimal flux fringing in the axial and transverse directions

  • 由于表面安装技术导致的最小转子谐波电流,其保持循环电路被隔绝而不会损失电磁或结构完整性

  • Minimal rotor air gap and air gap cooling requirements due to high strength composite sleeve that has near-zero losses from harmonic eddy currents

  • 由于CALNetix的PM转子的专有技术,高级电磁效率,转子尖端速度和行业领先的电力密度
