Asynchronous electric drive with enhanced survivability

摘要

The invention relates to electrical engineering, namely to the devices for controlling the number of revolutions of the motor and can be widely used in induction motors with adjustable survivability feature when repeated multiple failures. Asynchronous electric drive with high survival is based on n-sectional electric motor, each section of which is mounted on the same shaft and includes n-phase asynchronous electric motors whose phases through the respective current sensors are connected to respective three-phase frequency converters, the output of current sensors and inputs of all three-phase inverters connected to the microcontroller, which is connected to a speed sensor mounted on the shaft of asynchronous motors. Technical result: Control n-sectional three-phase electric motor with provision of its increased survivability in the event of single or multiple failures. 1 yl.
