paper is the presentation of LSIPMSM braking performance characteristics and the feasibility<br />
of its usage in passive brake systems, based on experimental data.<br />
Experiments were conducted on LSIPMSMs with symmetrical three-phase and two-phase<br />
phase stator windings, and by using with the same rotor. The full paper is going to present an<br />
in-depth analysis of current- and speed-dependant as well as current- and position-dependant<br />
characteristics of the tested LSIPMSMs, thus emphasizing important LSIPMSM braking<br />
performance attributes.<br />
Fig. 2 presents the phase A voltage, current, electrical output power and total electrical output<br />
power variation in dependence of the tested three-phase LSIPMSM braking torque.<br />

larger than the tested LSIPMSM rotor inertia) in dependence of the tested three-phase<br />
