| DESCRIPTION (english): | EMRAX motor is a completely new type of pancake axial flux brushless synchronous three phase AC (Alternating Current) electric motor. It can also work as a generator - technical data are the same - either EMRAX is used as a motor or as a generator.We achieved our objective and built a high-powered, high torque, extremely light, direct drive, low RPM, low noise electric motor, which efficiency is up to 96%. Because of the high torque EMRAX engine can achieve high power also at relatively low rotation speeds.The motor has much higher power-to-weight ratio compared to other brushless AC motors. We produce 9 different motor types: EMRAX 207; EMRAX 228 and EMRAX 268 - each type has 3 more subtypes High Volatage; Medium Voltage and Low Voltage. |
