Design and manufacture of electrical machines
The ERNEO team has expertise in the design and manufacturing of all types of electrical machines, from the most conventional to the most innovative. We offer kit electric motors that can be integrated into actuators or fully assembled electric motors.
Mastering the different types of electrical machines
Electrical machine types:
- Cylindrical machines (radial flux) with internal or external rotor
- Discoidal machines (axial flux) with single or double rotors, and single or double stators
- Linear machines
Electrical machine technologies:
- Permanent magnet synchronous (AC or DC Brushless)
- Non-salient (round) or salient poles
- Asynchronous
- Synchro-reluctance (SynRM)
- Permanent magnet assisted synchronous reluctance motor (PMA-SynRM)
- Variable reluctance
- Wound rotor
- Hysteresis
- Polyphase
