In this chapter, authors suggest an approach to the shaft load simulations and
calculations of the electrical machine efficiency with the use of OrCAD PSpice
Designer Software, and in particular, visual programming of analogue component
blocks. Also, a method for modifying the EM dynamic model is put forward. This
method enables researchers and designers to acquire data for plotting static mechanical,
electromechanical and performance curves vs the angular speed of the rotor. These data
are obtained by modifications to the block-diagram of the motion equation of the drive
where the instantaneous values of the electromagnetic torque of the motor and the load
torque are equal by absolute values and opposite to each direction.
Keywords: Analog component, Dynamic Model, Efficiency, Electrical Machine, Equation of Motion, load Torque, PSpice, Simulation, Static Curve.
