Australia has the world's second largest reserve (after China) of high energy-density permanent magnet (neodymium-iron-boron) material for the IPM motor. The present limitation of the machine to be driven sensorless over a wide speed range with field weakening is believed to be holding back its widespread use in applications other than servo-type which requires high-resolution mechanical sensors. Extension of the motor speed range by a combination of magnetic system design (for large field weakening range), and sensorless position and flux estimation with sufficient accuracy for fast dynamic control should lead to large scale adoption of this motor, and hence to significant improvement in energy efficiency and market share for Australia.

澳大利亚拥有世界第二大IPM电机用高能量密度永磁（钕铁硼）材料储备（仅次于中国）。目前的限制的机器被驱动传感器在一个广泛的速度范围内与磁场减弱被认为是阻碍其广泛使用的伺服类型以外的应用，需要高分辨率的机械传感器。通过磁系统设计（用于大的磁场减弱范围）和具有快速动态控制的足够精度的无传感器位置和磁通估计的组合来扩展电动机速度范围应导致该电动机的大规模采用，从而显著提高澳大利亚的能源效率和市场份额。
