| in the palette | on the schematic |
The block is designed to simulate a simplified electric drive or generator described by the equations:
where:
- T – torque, Nm
- K – converter gain, V·s/rad
- I – current, A
- U – voltage at the converter, V
- ω – relative angular speed, rad/s
The relative angular speed is calculated by the formula:
where ωC and ωR – angular speeds at ports "C" and "R", respectively, rad/s
The torques at the block ports are defined as:
TC and TR – torques transmitted to ports "C" and "R", respectively, Nm.
The positive direction of current and voltage is taken as the direction from port "+" to port "-". In the electric drive mode, the voltage and current have the same signs, in the generator mode – the opposite.
