The brushless dc machine has constant torque and constant power operation with field weakening up to high speeds due to reluctance torque. It has larger torque for the same peak current and voltage as its competitors. Low inertia, no maintenance, and no heat producing components on the rotor are also attractive benefits when used for ISG. The main drawbacks are due to the PM: high costs, magnet corrosion and demagnetisation. This type of motor needs to be rated for higher power than IM for the same speed range and higher stator current over the field weakening region. Honda uses such machines in its advanced integrated motor assist (IMA) systems installed in small passenger cars. 无刷直流电机有一个恒定的转矩输出和恒功率输出在高速段利用弱磁可以升速，与其他电机相比之下它在相同的电流电压下拥有更大的转矩。很低的惯性，免维护，转子上不会发热，这些都是无刷电机用作ISG时的优势。但是它的最大的缺点就是磁钢：磁钢很贵，磁钢的腐蚀和去磁的危险。这样的无刷电机与同速度段的异步机相比需要更大的功率，而且在弱磁区域需要更大的定子电流。本田使用这样的电机在他的先进的集成电机辅助系统中，叫做小型旅行车。 Machines based on the principle of variable reluctance offer a cheap and robust alternative to conventional polyphase machines. Reluctance machines have salient poles within the rotor and the stator. Therefore the inductance of the direct axis differs from that of the quadrature axis. The torque is developed due to the principle of the minimisation of the energy stored within the air-gap. The rotor has no excitation and is magnetised by the stator. Even at high speed the machine can be switched off electrically. High temperatures surrounding the machine have less or no effect [10]. 可变电感的电机与多相电机比较起来拥有更便宜和更强大的能力。磁阻电机在转子和定子中都有隐藏的磁极。所以电机的直轴和交轴的电感不相等，产生转矩的原理就是基于减少气隙中储存的磁能的原理。转子没有激励源而是通过定子的磁场进行铰链，在高速段电机可以被电子
