motulator: Motor Drive Simulator in Python

This open-source software includes simulation models for an induction machine, a synchronous reluctance machine, and a permanent-magnet synchronous machine. The machine models are simulated in the continuous-time domain while the control methods run in discrete time. The default solver is the explicit Runge-Kutta method of order 5(4) from scipy.integrate.solve_ivp. A number of control methods are provided as examples. The example methods aim to be simple yet feasible.
