The series motor (with the demonstration generator system)

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

1. Observe the number of revolutions and the current when changing the operating voltage.
2. Observe the direction of rotation when reversing the polarity of voltage and various connections.
3. Observe the number of revolutions and the current when applying load.
