摘要:
 摘要:针对多定子永磁直线同步电机(PMLSM)运行过程中绕组切换故障可能引起的失步问题,
研究了绕组切换故障特性。在分析PMLSM推力功角特性的基拙上,研究了频率对稳定运行区间
的影响规律,建立了考虑出入端效应的多定子PMLSM推力模型,研究了绕组切换故障对稳定性的
影响规律,利用样机进行了实验研究,得到了一台及两台绕组切换故障时,电机运行频率、运行方式
对运行特性的影响规律。研究结果表明:低速PMLSM的电阻效应不能忽略,动子所受正向推力作
用空间变小,负向推力作用空间增大。相同数量的绕组失电,提升运行时较易失步。失电绕组越
多,剩余电机承担电流越大,越易引起失步。
Abstract:
 Abstract:Since the windings of multi-primary permanent magnet linear synchronous motor(PMLSM)
switching failure may cause motor lose step,characteristics of windings switching failure was researched.
On the analysis of thrust power angle characteristic of PMLSM,the influence of frequency on stable oper-
anon area was researched. The thrust model with entry and exit effect of multi-primary PMLSM was con-
structed and the influence of windings switching failure on stable characteristic was researched. A multi-
primary PMLSM prototype was applied to experiments. The influence of motor operating frequency and
operation mode on running characteristics was obtained when one or two primary windings switching fails.
The research results show that the impact of primary resistance is not negligible when the operating fre-
quency of PMLSM is low. The forward thrust stable operation region is reduced and downward stable op-
eration region is increased. If the stator windings switch failed when going upward,the motor is easy to
out of step. The more number of switching failure windings is,the greater current of residual windings is,
and the easier of the PMLSM is out of step.
