Koopman, Electric Motors Supplied by Nonsinusoidal Voltages, 1966. The report covers a study to represent electric motors on analog computers, with the representation being usable when the motor is supplied by nonsinusoidal voltages. Such a representation is of particular interest when matching characteristics of static inverters and motors powered from them.
