- The motors do not require speed encoders so there is no need for speed encoder feedback (lower component/installation/assembly/cabling costs).
- The speed accuracy of single-motor and multi-motor drives is directly proportional to the frequency of the power supply system of the inverter.
- The motors in multi-motor drives run synchronously without additional electronic overhead.
- This principle results in low losses of the rotor and excitation, and this leads to a high level of efficiency comparable with other motors, and savings on operating and energy costs.
- Constant torque in the defined frequency range
- Load-independent speed over the frequency range
- Electrical braking, holding torque at standstill possible with DC
- Demagnetization-proof motor design
- High degree of protection
