Machines
The Simple Brushless DC Machine is a model of a permanent magnet synchronous machine with trapezoidal back EMF.
The machine operates as a motor or generator; the sign of the mechanical torque determines the mode of operation (positive for motoring, negative for generating). In the component icon, phase a of the stator winding is marked with a dot.
The electromagnetic torque is:
Mechanical rotor speed:
Mechanical and electrical rotor angle:
The output vector "m" contains the following 6 signals:
