However, the traditional order analysis methods require the tachometers to obtain the speed information. This paper proposes a novel tacholess OA method for brushless direct current motor (BLDCM) ...

The main contribution is a detailed description of the algorithm design process applied to BLDCM for commutation torque ripple minimization, which points out that the optimal conduction status is ...

无刷直流电机（Brushless Direct Current Motor，简称BLDCM）由电动机主体和驱动器组成，是一种典型的机电一体化产品。无刷电机是指无电刷和换向器（或集电环）的电机，又称无换向器电机。这是模型中除了有刷电机以外用的最多的一种电机，无刷直流电机不使用 ...

In this paper, the Benettin–Wolf algorithm to determine all Lyapunov exponents for a class of fractional-order systems modeled by Caputo’s derivative and the corresponding Matlab code are presented.

0 引言 无刷直流电机(以下简称BLDCM)用电子换相器取代机械换向器，根除了电刷和换向器接触磨损所导致的寿命周期短、电气绝缘低、火花干扰强等诸多缺陷;同时永磁材料的高磁性能使无刷直流电机具有起动转矩大、调速范围广、运行效率高等优点，在各个工业 ...
