Electrical machines
3-phase induction
Explore how a rotating magnetic field produces torque in a squirrel-cage rotor.
Open simulator →Interactive engineering lab
See electricity in action.
Open a component, change its electrical conditions and observe the physics through an interactive 3D model and characteristic curves.
Electrical machines
Brushed DC
Explore how brushes and a commutator keep the armature torque rotating in one direction.
Open simulator →Electrical machines
Brushless DC
Observe how the inverter energizes three-phase stator windings in sequence to rotate a permanent-magnet rotor.
Open simulator →Semiconductors
N-channel MOSFET
See how gate voltage creates a conductive channel and controls drain current between source and drain.
Open simulator →Semiconductors
P–N junction diode
See how the depletion region enables forward current, blocks reverse current and changes during breakdown.
Open simulator →Transformers & magnetics
Transformer
Observe how alternating magnetic flux transfers energy from the primary winding to the secondary winding.
Open simulator →Passive components
Resistor
Observe how resistance limits current, drops voltage and converts electrical energy into heat.
