e+a motor elements are airborne
For the all-electric aircraft e-Sling, which was developed and built as part of a student project at ETH Zurich, e+a acted as sponsor for the electromagnetic and mechanical design as well as the production of the motor elements for the aircraft propulsion system.
With a take-off power of 110 kW at 2300 min-1, the power-to-weight ratio of the air-cooled motor is 5 kW/kg.
NEW - More than 1 million acceleration cycles for IPM synchronous rotor
To investigate the fatigue strength of IPM synchronous rotors with internal magnets, e+a carried out an acceleration test and achieved more than 1 million acceleration cycles.
The test rig used for this purpose is scalable and can be used for extended investigations. Contact us, we will be happy to advise you on the choice of the right motor element for you.
NEW - VPA-Voltage Peak Analyser
e+a has developed the VPA-Voltage Peak Analyser measuring device to analyse the entire drive system consisting of converter, motor element and peripheral devices and is now offering:
- VPA voltage peak analyser
- Determination of the e+a load index for assessing the overall system consisting of inverter, motor element and peripheral devices
- Supplementary training on the subject
- Measurement services in the context of commissioning
e+a will be happy to advise you and provide further information if you are interested. Contact our engineers.
