Principle

An electromotor can also be operated with an electromagnet as a field magnet. If armature coils and field coils are connected in series, then this is called a series-wound motor. The properties of this motor are studied by observing the direction of rotation and measuring the electric current.

Benefits


Demonstrative experiment due to large instruments

Easy and sturdy setup

Display of measuring range, kind of current and unit also on the back side


Tasks


Observe the number of revolutions and the current when changing the operating voltage.

Observe the direction of rotation when reversing the polarity of voltage and various connections.

Observe the number of revolutions and the current when applying load.
