Inductance

Inductance

Inductance. Al Penney VO1NO. Inductance. Inductance is the property of an electrical circuit that opposes a change in current. In a DC circuit inductance has an effect only when the DC starts , or when attempts are made to stop it.

Motor Operation. DC motors are built the same way as generators Armature of a motor connected to a dc power supply When switch is closed a large current flows through the armature winding due to its low resistance Armature is within a magnetic field A force is exerted on the windings

Today’s agenda: Induced Electric Fields.

Today’s agenda: Induced Electric Fields. You must understand how a changing magnetic flux induces an electric field, and be able to calculate induced electric fields. Eddy Currents. You must understand how induced electric fields give rise to circulating currents called “eddy currents.”
