modelDCBase
Base DC machine
Extends from Ports.Port_p (One port, 'positive').
Information
Contains the pole-pair transformation
pp*airgap.phi = phi_el; airgap.tau = -pp*tau_el;
between the 'electrical' variables phi_el and tau_el and the 'mechanical' variables airgap.phi and airgap.tau.
The connector 'airgap' transfers the electromagnetic rotor-torque to the mechanical system.
