Dynax是一种由永磁体转子和带轴向绕组的爪极式定子组成的电机。其中含永磁体镀层的玻璃纤维转子属于首创,其并未使用护铁。该电机可以显著提高输出转矩并扩展电机的速度运行范围。它具有比较高的漏感和低短路电流,从而使其在宽速度范围内的弱磁运行成为可能。由于其典型的极对数多的特点,逆变器和电机的控制需承受较高的基波频率。本文对其优点,特别是在交流起动机和电动汽车中的应用作了着重介绍,同时也介绍了在电机控制中的一些特殊要求。 Dynax is a motor consisting of a permanent magnet rotor and a claw-pole stator with axial windings. Which contains the permanent magnet coating glass fiber rotor is the first, it did not use back iron. The motor can significantly increase the output torque and extend the motor’s speed operating range. It has a relatively high leakage inductance and low short-circuit current, making it possible to operate a weak field over a wide range of speeds. Due to its typical pole-to-pole count, inverter and motor control must withstand higher fundamental frequencies. This article focuses on its advantages, particularly in AC starters and electric vehicles, and introduces some special requirements in motor control.
