DC drives
Advantages of electrically-controlled DC drives:
- Wider speed adjustment range
- Precise smooth running of motor shaft
- Good control features with simple control structure
- Highly dynamic performance
The DC speed controllers feature integrated power regeneration when it comes to generator operation. Owing to these characteristics the electronic DC drives are versatile variable-speed drives for almost all applications. The commutator design and the carbon brushes guarantee a long brush service life.
Direct current motors for DC speed controller operation make high demands on commutation.
The following characteristics of DC motors guarantee non-sparking commutation:
- 4-pole structure with commutating pole
- Main poles in special geometrical arrangement for suppression of armature reaction.
They also ensure high carbon brush service life (up to 15,000 h) � even with increased starting and braking torque.
