Series and parallel DC machines for classical and low cost drive systems.
Squirrel cage and wound rotor induction machines are the workhorse in industry. Various models exist ranging from industry applications to generators in wind turbines.
Easy to use models allow the parametrisation using name plate data, while other models are modeled using the classical Ls Lr and Lm parameters and even allow inclusion of saturation.
Both synchronous motors as well as generators are available.
The Hydro and Turbo generator models allow for modeling of active and reactive power, control of speed and field for control in power system generation simulations.
Synchronous reluctance machines are included in the library where Ld and Lq can be modeled independently.
Permanent Magnet Synchronous Machines PMSM
Both outer rotor and interior PMSM IPM motors for servo and traction drive systems are modeled.
Saturation and harmonics can be included in the Brushless AC machine model.
The classical brushless motor for servo applicaiotn is available, including HALL sensors.
The bipolar and unipolar stepper motor model can be used in single, half and microstepping drives..
The SRM motor model is defined for various configurations, being it 10/8, 12/8, 6/8, 8/6 and 6/4.
